Product details

HK-1309pHEComputational typepHOnline monitoring device, which can be calculated by measuring the specific conductivity and positive conductivity of ammonia based pure waterpHIt can simultaneously monitor the specific conductivity and hydrogen conductivity of the sample waterpHAmmonia contentEDIMultiple targets such as traffic. Mainly used for monitoring the water quality of condensed water, deaerator inlet feedwater, economizer inlet feedwater, saturated steam, superheated steam, and heat network heater drainage in the water vapor cycle system of thermal power plants.

This product comes with hydrogen conductivity electro deionization(EDI)The module utilizes electrodialysis technology and ion exchange technology to achieve directional migration of ions in the sample water under the action of an electric field, thereby achieving the removal of cations in the sample water. Fundamentally solving the problems of tedious resin replacement and fault measurement in traditional measuring devices.
