Overview
A Simple Sensor Design
Measure monochloramine without having to deal with
messy reagents or expensive sample conditioning
systems.
Integral Pt-100 RTD allows for automatic temperature
compensation.
Operates in samples up to 50 °C (122 °F).
Measures 0 to 15 ppm monochloramine.
Ease of Maintenance and Installation
1 in. MNPT process connections suitable for mounting in a
low flow cell installed in a sidestream sample or directly in
a chlorine contact basin.
Replacing the membrane and electrolyte solution is fast
and easy and requires no special tools or fixtures.
Variopol (VP6) cable connection option, for quick cable-
to-sensor release, eliminates cable twisting.
