Overview
HANNA HI981402-02 is a Wall-Mounted waterproof pH measurement controller with LCD display and alarm LED lights. HI1286PEI acidity pH Electrode with chemical corrosion resistance and PTFE anti-clogging dialysis membrane protective sleeve design ensures measurement accuracy and extends Electrode life. Supports manual two-point calibrating and alarm functions for continuous monitoring applications.
Features
1. Appearance design, LCD screen display, simple and convenient operation
2. Manual two-point calibrating (pH4.01, 7.01)
3. Alarm function, alarm point setting range is 3-11pH
4. Designed for continuous measurement, with good waterproof performance
5. Equipped with HI1286PEI material acidity pH Electrode, chemical corrosion resistance
6. Unique PTFE anti-clogging dialysis membrane protective cover design to ensure accurate measurement and prolong Electrode service life
Principle
The pH measurement controller detects the pH value in the solution through HI1286 custom plastic acidity composite Electrode, which is designed with PEI material and PTFE anti-clogging dialysis membrane protective cover to ensure stable measurement. When the measurement reading exceeds the set alarm point +/- 0.5pH, the red LED alarm light flashes to alert.
Applications
Hydroponics, greenhouses, horticulture
Steps
1. Install the device and connect HI1286 Electrode
2. Perform manual two-point calibrating (using pH4.01 and 7.01 standard buffers)
3. Set the alarm point (range 3-11 pH)
4. Start continuous monitoring of ph value
Notice
• The alarm setting range is 3-11pH, and the red LED light will flash when the setting value is exceeded +/- 0.5pH
• Operating Ambient Temperature 0~ 50ºC
• relative humidity must not exceed RHmax 95% non-condensing
• Use dedicated HI1286 Electrode and calibrated point
Make sure the Power Adapter matches (230VAC/12VDC)
