Product Details

GNST-ORP 226 online sensorThe analyzer adopts platinum ring glass electrochemical method, corrosion-resistant shell, built-in NTC temperature sensor, and uses RS485 interface and standard Modbus protocol.

Application field

The instrument is widely used in industries such as environmental surface water, municipal sewage, industrial wastewater, industrial process water, swimming pools, etc. and has received high praise from a large number of users.

GNST-ORP 226 online sensorProduct Principle

The ORP sensor uses platinum electrode as the indicator electrode, and the Ag/AgCl reference electrode is combined with the water sample to form the primary battery. Measure the oxidation-reduction potential of platinum electrode relative to the saturated Ag/AgCl reference electrode using an electronic millivoltmeter, and then convert the oxidation-reduction potential of the composition relative to the standard hydrogen electrode as the report result.

And = End + Up

Where:

En - oxidation-reduction potential of the tested water sample, mV；

Eind - measured oxidation-reduction potential of water sample, mV；

Eref - measure the potential of saturated Ag/AgCl sensor at temperature, mV；。
