The HI981404N is ideal for growers that need to monitor pH and TDS for optimal plant growth. This meter continuously monitors and displays the values of a solution on an easy-to-read set of LCDs.
HI 981404N is ideal for agricultural, horticultural and hydroponics applications where pH and TDS levels need to be continuously monitored for optimal plantgrowth.
HI 981404N continuously monitor and display the pH and TDS values of a solution on an easy to read set of dual LCD’s.
The HI 1286 gel filled pH electrode is replaceable and the BNC connector is protected behind a waterproof sheath. 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. Both models are equipped with a grounding bar to ensure more accurate pH measurements and longer electrode life.
The HI 981404N are compact and easy to install and use. This makes them ideal for all continuous monitoring applications.
