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