BRAND NEW HANNA HI 991401 pH Gro'Chek® pH and Temperature Monitor with Large Backlit LCD

HI 991401 pH Gro'Chek® pH and Temperature Monitor with Large Backlit LCD

This indicator from HANNA® has a large, dual-level backlit LCD to give you instantaneous readings of both pH and temperature, even from a distance. The HI 991401 microprocessor provides for automatic calibration, automatic buffer selection and automatic temperature compensation.

HI 991401's waterproof housing has been designed to meet the grower's need, and 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 interchangeable pH electrode and 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!
