HI 981404N-01

pH & TDS Continuous Indicator

HI 981404N-01 is ideal for agricultural, horticultural and hydroponics applications where pH and TDS levels need to be continuously monitored for optimal plant growth. This instrument continuously monitors and displays the values of a solution on an easy to read set of LCD’s.
The HI 1286 gel filled pH electrode is replaceable and the BNC connector is protected behind a waterproof sleeve. The unique design of the electrode guarantees greater clogging resistance 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.
This model is equipped with a grounding bar to ensure highly accurate pH readings and longer electrode life.

The HI 981404N-01 is compact and easy to install and use making it ideal for all continuous monitoring applications.
