2-Ring Cell Conductivity and Temperature Industrial Smart Probe

Works with Universal Process Controllers (HI510 and HI520)

HI7630-28 is a conductivity and temperature probe that is designed to be paired with the HI510 or HI520 Universal Process Controller.

The probe is recommended for a wide range of water applications, especially pure and ultrapure water. Two-electrode probes can be calibrated using a standard with a value close to the measurement value.

An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation standards:

• Linear: appropriate when it is assumed that the temperature coefficient of variation has the same value for all measurement temperatures.
• Standard: appropriate for high-purity water measurements and documented in ASTM Standard D5391-14. This setting should be used for resistivity measurements.
• Natural: appropriate for natural ground, well, or surface water (or water with similar composition) in accordance with ISO7888 standard.
