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