Product information "HI981405N pH / EC & TDS-Indicator with Electrode GRO'CHEK"
HI 981405N-02 is ideal for agricultural, horticultural and hydroponics applications where pH and EC 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.
This model is equipped with a grounding bar to ensure highly accurate pH readings and longer electrode life.
The HI 981405N-02 is compact and easy to install and use making it ideal for all continuous monitoring applications.
