This waterproof pH indicator has been designed to meet the grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. Measurements are highly accurate and can be verified with one or two point calibration. Low batteries and battery changes are no longer a problem thanks to a 12VDC power supply included with the meter. The electrode is interchangeable and has been specially designed to address the needs of growers. Its design guarantees greater clogging resistance in fertilizer solutions with higher concentrations of phosphate, nitrate, etc. THis is a major improvement ensuring longer life of your electrode!

Supplied complete with HI 1293D pH electrode, fixed temperature probe, pH 4 and pH 7 calibration solutions (20mL each), 12 VDC adapter, and instructions
