Hanna® GroLine Waterproof pH/EC/TDS/Temperature Combo Meter 

(Model HI 9814)

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.

HI9814 is supplied with HI1285-7 multi-parameter probe, HI50036-0 Quick Cal buffer solution sachet (3), HI700661 pH electrode cleaning solution sachet for agriculture (3), 1.5 AAA batteries (3), and instructions.
