The HI1285-7 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. 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.

The HI1285-8 multiparameter probe measures pH, EC/TDS, and temperature in one convenient, rugged probe. Use with the HI981420 GroLine Monitor to provide around-the-clock, continuous monitoring of pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions.

The HI9813-61 and HI9810-61 are supplied with the HI1285-61 pH/EC/TDS/temperature probe with CAL Check^™. The pH, EC, TDS, and temperature sensor are housed in a single body that connects to the meter with a DIN connector.
