Hanna HI 981401N - pH Gro'Chek Water Resistant pH Indicator


Gro'Chek Water Resistant pH Indicator
  • Water resistant
  • One or two point calibration
  • Electrode clog resistance

The pH indicator HI 981401N has been designed to meet the grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. The housing is water resistant and features a molded eye which allows installation right above the sample to be monitored.

Measurements are highly accurate and can be verified with two point calibration. With a 12 VDC power supply included with the meter, low battery failures are never an issue. The electrode is interchangeable and the connector is well protected behind a waterproof sleeve. The meter is supplied with a stainless steel probe, preventing potential grounding problems and ensuring extended electrode life.

The gel-filled pH electrode has been specially designed to address the needs of growers. Its design guarantees greater clogging resistance in fertilizer solutions with high concentrations of nutrients such as phosphate and nitrate.
