This continuous reading meter 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 LCDs.

The 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. It is compact and easy to install and use, making it ideal for all continuous monitoring applications.
