GroLine Hydroponic Waterproof pH/EC/TDS/Temperature Portable Meter - HI9814
The HI9814 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single amplified probe. The meter operation is simplified with two buttons. One is used for on/off and for calibration while the other is used to switch between the measurement modes. The HI9814 has advanced features including a selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm).
- 3 in 1 amplified probe with pH, EC/TDS and temperature sensors
- Quick Cal Mode to calibrate pH and EC/TDS with one solution
- EC to TDS Conversion factor selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
The HI9814 portable meter features a large multi-level LCD which displays both pH, EC or TDS and temperature readings simultaneously. The pH readings are displayed with a 0.01 resolution and an accuracy of +/-0.01 pH while the EC and TDS readings are displayed with a 0.01 mS/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. The EC range of the HI9814 is from 0.00 to 6.00 mS/cm and TDS is from 0 to 3000 ppm using the 0.5 conversion factor. The EC to TDS conversion factor is selectable 0.5 (500) and 0.7 (700 ppm). A built-in temperature sensor allows for automatic temperature compensated measurements of EC and TDS. The HI9814 has many advanced features that are found in more expensive portable instrumentation including automatic calibration, buffer/standard recognition and temperature compensation. The LCD screen has indicators for calibration status and stability, as well as on-screen tutorial messages. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The supplied HI1285-7 is a polypropylene body, amplified pH electrode with a built-in EC/TDS and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and sources of electrical noise include circulating pumps, motors, and ballasts for grow lights. The HI9814 is a versatile meter designed for hydroponics, greenhouse, and agriculture applications.
Simplified one button calibration
One or two point pH calibration is automatic to a pre-programmed buffer set (4.01, 7.01 and 10.01) or single point pH and EC calibration with the Hanna Quick Cal calibration solution. To perform a quick cal calibration, simply press and hold the left power/mode button while in measurement mode for three seconds and let go to enter calibration mode. Once both pH and EC are calibrated "CAL OK" is displayed and the meter returns to measurement mode.
HI1285-7 polypropylene body amplified pH electrode with built-in EC/TDS and temperature sensors
The HI9814 is supplied with an amplified polypropylene body pH/EC/TDS/temperature probe. The built-in amplifier will reduce the effects of electrical noise on the high impedance pH measurement. Examples of sources of electrical noise include circulating pumps, motors, and ballasts for grow lights.
