The HI991401 Gro’Chek pH and Temperature Monitor has a large, dual-level backlit LCD to give you instantaneous readings of both pH and temperature, even from a distance. The HI991401 microprocessor provides for automatic calibration, automatic buffer selection and automatic temperature compensation.
This waterproof indicator has been specially designed to meet the grower’s need for equipment suited to the aggressive environments of agricultural and hydroponics applications. Measurements are highly accurate and the meter can be calibrated at one or two points.
Low battery and battery changes are no longer a problem thanks to a 12 Vdc power supply included with the meter.
The HI 1293D pH electrode & the temperature probe have been molded with pipe thread (½’’ NPT), which allows the user to attach them to an in-line system. Moreover, the pH electrode has been specially designed to guarantee greater clogging resistance in fertilizer solutions with high concentrations of phosphate and nitrate.
