GENERAL DESCRIPTION

HI 98127 and HI 98128 are waterproof pH and temperature meters. The housing has been completely sealed against humidity and designed to float. All pH readings are automatically temperature compensated (ATC), and temperature values can be displayed in C or F units. The meters can be calibrated at one or two points with auto-buffer recognition and against five memorized buffer values. Measurements are highly accurate with a unique stability indicator right on the LCD. These meters are also provided with battery level indication at start-up, and with a low battery symbol which warns the user when the batteries need to be replaced. In addition the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low voltage level by turning the meter off. The HI 73127 pH electrode, supplied with the meters, is interchangeable and can be easily replaced. The stainless steel encapsulated temperature sensor facilitates faster and more accurate temperature measurement and compensation.

CALIBRATION

For better accuracy, frequent calibration of the instrument is recommended. In addition, the instrument must be recalibrated whenever: a) The pH electrode is replaced. b) After testing aggressive chemicals. c) Where high accuracy is required. d) At least once a month. Calibration procedure From normal measuring mode, press and hold the /MODE button until OFF on the secondary LCD is replaced by CAL. Release the button. The LCD enters the calibration mode displaying pH 7.01 USE (or pH 6.86 USE if the NIST buffer set was selected). After 1 second the meter activates the automatic buffer recognition feature. If a valid buffer is detected then its value is shown on the primary display and REC appears on the secondary LCD. If no valid buffer is detected, the meter keeps the USE indication active for 12 seconds, and then it replaces it with WRNG, indicating the sample being measured is not a valid buffer. For a single-point calibration with buffers pH 4.01, 9.18 or 10.01, the meter automatically accepts the calibration when the reading is stable; the meter displays the accepted buffer, with the message OK 1. After 1 second the meter automatically returns to the normal measuring mode. If a single-point calibration with buffer pH 7.01 (or pH 6.86) is desired, then after the calibration point has been accepted the /MODE button must be pressed in order to return to normal mode. After the button is pressed, the meter shows 7.01 (or 6.86) - OK 1 and, after 1 second, it automatically returns to the normal measuring mode. Note: It is always recommended to carry out a twopoint calibration for better accuracy. For a two-point calibration, place the electrode in pH 7.01 (or pH 6.86) buffer. After the first calibration point has been accepted, the pH 4.01 USE message appears. The message is held for 12 seconds, unless a valid buffer is recognized. If no valid buffer is recognized, then the WRNG message is shown. If a valid buffer (pH 4.01, pH 10.01, or pH 9.18) is detected, then the meter completes the calibration procedure. When the buffer is accepted, the LCD shows the accepted value with the OK 2 message, and then the meter returns to the normal measuring mode. Note: When the calibration procedure is completed, the CAL tag is turned on.

To quit calibration and to reset to the default values After entering the calibration mode and before the first point is accepted, it is possible to quit the procedure and return to the last calibration data by pressing the /MODE button. The secondary LCD displays ESC for 1 second and the meter returns to the normal measuring mode. To reset to the default values and clear a previous calibration, press the SET/HOLD button after entering the calibration mode and before the first point is accepted. The secondary LCD displays CLR for 1 second, the meter resets to the default calibration and the CAL tag on the LCD disappears.
The pH electrode can be easily replaced by using the supplied tool (HI 73128). Insert the tool into the electrode cavity as shown below.
Rotate the electrode counterclockwise.

Setup mode allows the selection of temperature unit and pH buffer set. To enter the Setup mode, press the /MODE button until CAL on the secondary display is replaced by TEMP and the current temperature unit (E.g. TEMP C). Then: for C/F selection: Use the SET/HOLD button. After the temperature unit has been selected, press the /MODE button to enter the buffer set selection mode; press the /MODE button twice to return to the normal measuring mode. to change the calibration buffer set: After setting the temperature unit, the meter will show the current buffer set: pH 7.01 BUFF (for 4.01/7.01/10.01) or pH 6.86 BUFF (for NIST 4.01/6.86/9.18). Change the set with the SET/HOLD button, then press /MODE to return to normal measuring mode. Insert a new pH electrode following the above instructions in reverse order.

OPERATIONAL GUIDE

To turn the meter on and check the battery status Press and hold the /MODE button until the LCD lights up. All the used segments on the LCD will be visible for 1 second (or as long as the button is pressed), followed by the percent indication of the remaining battery life (E.g. % 100 BATT). Taking measurements Submerge the electrode in the solution to be tested while stirring it gently. The measurements should be taken when the stability symbol on the top left of the LCD disappears. The pH value automatically compensated for temperature is shown on the primary LCD while the secondary LCD shows the temperature of the sample. To freeze the display While in measurement mode, press the SET/HOLD button. HOLD appears on the secondary display and the reading will be frozen on the LCD (E.g. pH 5.78 HOLD). Press any button to return to normal mode. To turn the meter off While in normal mode, press the /MODE button. OFF will appear on the secondary display. Release the button.

BATTERY REPLACEMENT

The meter displays the remaining battery percentage every time it is switched on. When the battery level is below 5%, the symbol on the bottom left of the LCD lights up to indicate a low battery condition. The batteries should be replaced soon. If the battery level is low enough to cause erroneous readings, the meter shows 0% and the Battery Error Prevention System (BEPS) will automatically turn the meter off. To change the batteries, remove the 4 screws located on the top of the meter.

pH ELECTRODE MAINTENANCE

When not in use, rinse the electrode with water to minimize contamination and store it with a few drops of HI 70300 storage solution in the protective cap. DO NOT USE DISTILLED OR DEIONIZED WATER FOR STORAGE PURPOSES. If the electrode has been left dry, soak in storage solution for at least one hour to reactivate it. To prolong the life of the pH electrode, it is recommended to clean it monthly by immersing it in the HI 7061 cleaning solution for half an hour. Afterwards, rinse it thoroughly with tap water and recalibrate the meter. Once the top has been removed, carefully replace the 4 batteries located in the compartment while paying attention to their polarity.
Replace the top, making sure that the gasket is properly seated in place, and tighten the screws to ensure a watertight seal.

About 1.1 Klx for 12 hours per day are necessary simply to maintain plant quality for one year and at least 2.1 Klx for 12 hours per day are necessary for foliage plants to manifest any benefit from fertilization. While lack of sufficient light results in poor plant growth, too much light can also be harmful. Shade plants cannot tolerate excessively high light levels. When a plant receives too much direct light, the leaves bleach or scald, sometimes dying. This often happens after moving a plant outdoors in direct light. Any changes in light intensity should be gradual.

Plant Nutrition

The three elements that are most needed by plants are nitrogen (N), phosphorous (P) and potassium (K). This is the reason why they are called macronutrients and should be given to plants.
Phosphorous is an important element in the composition of DNA and RNA, the regulators of the energetic exchange (ATP & ADP), as well as the reserve substances in seeds and bulbs. It contributes to the formation of buds, roots, blooming, and lignification.
A lack of phosphorous results in: stifling of plant, slow growth, a reduction of production, smaller fruits and a lower expansion of the roots. Even if Potassium is not a constituent of important compounds, it plays a remarkable role in many physiological activities like the control of cellular turgor and the accumulation of carbohydrates. It increases the size of fruits, their flavor, as well as yielding a positive effect on the color and fragrance of flowers. Potassium also makes plants more resistant to disease.
Nitrogen is indispensable for the plants life and is a key factor in fertilization. Nitrogen allows the
development of the vegetative activity of the plant, in particular, causes lengthening of trunks and sprouts and increases the production of foliage and fruits. An excess of nitrogen weakens the plants structure creating an unbalanced relationship between the leaves and the stalks. In addition, the plant becomes less resistant to diseases.
