HANNA HI 981404 pH/TDS Monitor for Agriculture with Range up to 1990 ppm (mg/L)
HANNA HI 981404 pH/TDS Monitor for Agriculture with Range up to 1990 ppm (mg/L), HI981404N, HI 981404, HI981404 HI981404-01, HI981404-02 Indicator
HI 981404N and HI 981405N are both ideal for agricultural, horticultural and hydroponics applications where pH and TDS or pH and EC levels need to be continuously monitored for optimal plant growth. HI 981404N and HI 981405N continuously monitor and display the pH and TDS or pH and EC values of a solution on an easy to read set of dual LCD's.
The HI 1286 gel filled pH electrode is designed with the BNC connector protected behind a waterproof sheath and when exhausted is replaceable. The unique design of the electrode guarantees greater resistance to clogging in fertilizer solutions with high concentrations of phosphate, nitrate, etc. TDS measurements are performed using the 4-4-2 conversion factor of 0.7 so you do not need to convert the readings. Both models are equipped with a grounding bar to ensure more accurate pH measurements and longer electrode life.
HI 981404N and HI 981405N are compact and easy to install and use. This makes them ideal for all continuous monitoring applications.
