GroChek Hanna PH Continuous Meter HI-981401
GroChek Hanna PH Continuous Meter HI-981401
Continuous Read, Water-resistant pH Indicator with Alarm The innovative pH GroChek has been designed to meet the growers need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. The water-resistant monitor has a molded eye for easy installation right above the sample to be monitored. Customized setpoints are user-adjustable and a red LED will alert the user as soon as an abnormal situation arises. Measurements are highly accurate and can be verified with your choice of one or two point calibration. Low batteries and frequent battery changes are no longer a problem as the pH GroChek is equipped with a 12 VDC power supply. The probes are interchangeable and the connectors are well-protected behind a waterproof sheath. 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 phosphate, nitrate, etc. This is a major improvement ensuring longer life for your electrode and none of the hassles such as frequent calibrations and electrode changes. pH spot checks and continuous monitoring have never been this easy. pH measurement range of 0 - 14 with 99.8% accuracy. Alarm setpoint is adjustable between pH range of 3.0 and 7.0. Manual two-point calibration at 4.0 and 7.0. Includes HI 1286 double junction, Teflon® diaphragm pH electrode with 2 m (6.6') cable and BNC connector (included). Comes complete with starter calibration solution. Additional calibration solutions below. Two-year limited manufacturers warranty.
