The HI-1285 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 utilises 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 HI-1285 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, environmental monitoring, water treatment, and boilers and cooling towers.

• Pre-amplified pH electrode
• Amperometric EC/TDS sensor
• Built-in temperature sensor
• Designed for use with Hanna’s HI-9813, HI-9812, and HI-9811 portable multiparameter meters.
