The HI9814K comes as a complete kit for hydroponics nutrients, allowing you to start taking measurements as soon as you receive it. The HI9814K includes the HI9814 hydroponics meter, specialized 3-in-1 probe, pH/EC Quick Cal calibration sachets, storage solution, agriculture cleaning solution, and shockproof green rubber boot.
- Measure pH, TDS, & temp of your nutrient solution with one simple meter.
- One combined, pre-amplified pH, EC, and TDS (ppm) probe for hassle-free measurements.
- Designed especially for hydroponic, aquaponic, and greenhouse growers.
The HI9814 portable hydroponics 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 +/-0.05 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 0.01 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 measuring hydroponics nutrient levels in water.
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.
