HI 991401-01
Gro’Chek pH and Temperature Monitor
This indicator from HANNA has a large backlit LCD to give users instantaneous readings of both pH and temperature that can be easily read in dim light. The HI 991401-01 provides automatic calibration, automatic buffer selection and automatic temperature compensation.
HI 991401-01’s waterproof housing has been designed to meet the growers’ need for an indictor that is well suited to withstand the aggressive environments found in agricultural and hydroponics applications. Measurements are highly accurate and can be verified with one or two point calibrations. With a 12 VDC power supply included with the meter, low battery failures are never an issue.
The pH electrode has been specially designed to address the needs of growers. It’s design guarantees greater clogging resistance in fertilizer solutions with high concentrations of phosphate, nitrate, etc. to ensure longer electrode life.
