Product Description

Global Water’s Water Quality Sensors are rugged, industrial grade sensors designed for direct immersion or insertion into water streams.  Most sensors are powered by 10 to 36 VDC and all sensors have a linear 4-20mA output.  25′ cable lengths are standard, with optional cable lengths to 500′.
