HANNA HI 981401 GroChek pH Monitor / Indicator (HI981401 HI981401N HI981401-01 HI981401-02 HI 981401-01 HI 981401-02)
Hanna Instrument's innovative 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 the molded eye allows installation right above the sample to be monitored. Measurements are highly accurate and can be verified with one or two point calibration. This pH tester includes a 12 VDC power supply, large easy to read LCD screen, and pH electrode. The electrode is interchangeable and the connector is well-protected behind a waterproof sheath. This pH indicator is supplied with a stainless steel probe to prevent potential grounding problems ensuring extended electrode life. The gel-filled pH electrode has been specifically designed to address the needs of growers. Its design guarantees greater clogging resistance in fertilizer solutions with high concentrations of phosphate, nitrate, etc
