Product Introduction
1. Description of UK Detectronic Water Quality Sensor MMs-d010:
The ORAKEL series residual chlorine analyzers, residual chlorine controllers, and residual chlorine monitors are membrane devices that are insensitive to pH changes, require no reagents, are extremely stable, and reduce maintenance and lifecycle costs.
The thin-film amperometric chlorine sensor incorporates a third reference electrode to eliminate zero drift. Its unique design means pH correction is typically not needed at all, completely eliminating reagents.
In addition to advanced potentiostatic amperometric free chlorine and total chlorine sensors, the ORAKEL series residual chlorine analyzers have all the features you need, and more.
