Optical Dissolved Oxygen Electrode for HI510 and HI520 Controllers HI7640-58ZZ

Producer: HANNA Instruments

SKU: HANNA-HI7640-58ZZ Category: Hanna experimental measuring equipment

Optical Dissolved Oxygen Electrode for HI510 and HI520 Controllers

– The HI7640-58 is an optical dissolved oxygen electrode with Smart Caps HI764113-1

– Automatically compensates for atmospheric pressure, salinity (manual setting) and temperature

– Suitable for control and treatment applications in urban and industrial wastewater

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

– Smart Caps are factory calibrated

– NPT 3/4 ” connection thread

– Integrated temperature sensor

– Probe stores model, firmware, serial number and calibration information and Smart Cap data (serial number, installation date)

– Low maintenance requirements (no need to refill electrolyte solution or replace membrane as with membrane DO electrodes)

– Measurement reliability does not depend on flow rate

– Fast response time

– Stable measurement results even at low oxygen concentrations
