Galvanic Dissolved Oxygen Electrode for HI510 and HI520 Controllers HI7640-18ZZ

SKU: HANNA-HI7640-18ZZ Category: Hanna experimental measuring equipment

– The HI7640-18 is a galvanic membrane dissolved oxygen probe designed for use with the HI510 and HI520 controllers.

– The probe is suitable for continuous measurement of dissolved oxygen in water.

– An integrated temperature sensor measures the water temperature and adjusts the probe signal within the specified temperature range

– Suitable for municipal and industrial wastewater control and treatment applications.

– The probe can be installed directly in the pipe, immersed in a tank, or in a measuring cup.

– Easy to replace HDPE membrane

– Durable, chemical resistant PVDF (Kynar®) body

– NPT 3/4 ” connection thread

– Maximum pressure 3 bar

– Built-in temperature sensor for DO measurement and compensation

– Digital probe stores model, firmware, serial number and calibration information
