HI-981404N Waterproof pH/TDS Meter with Smart Electrode information

Hanna's extended description

The HI-981404N 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.

This meter is supplied with the HI-1286 replaceable gel filled pH electrode with BNC connector, protected behind a water resistant sleeve. The unique design of the electrode guarantees greater clogging resistance in fertiliser 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.

The HI-981404N is compact and easy to install and use making it ideal for all continuous monitoring applications. This meter is equipped with a grounding bar to ensure highly accurate pH readings and longer electrode life.
