The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb.
The EC/TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples.
The design consideration for the HI1285-7 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, and other agricultural applications. The HI1285-7 is designed for use with Hanna’s HI9814 portable multiparameter meter.
