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'.

WQ201 pH Sensor
 

Output: 4-20 mA Range: 0-14 pH Accuracy: 2% of full scale Maximum Pressure: 40 PSI Operating Voltage: 10-30 VDC Current Draw: 5.5 mA plus sensor output Warm Up Time: 3 seconds minimum Operating Temperature: -5° to +55°C Size of Probe: 1 1/4" diameter x 10" long Weight: 1 lb.

WQ301 Conductivity Sensor
 

Output: 4-20 mA Range: 0-5,000, 0-10,000, 0-20,000 Micro Siemens (micro mhos) per cm Accuracy: 1% of full scale Maximum Pressure: 40 PSI Operating Voltage: 12VDC (± 5%) Current Draw: 0.8 mA plus Sensor output Warm Up Time: 3 seconds minimum Operating Temperature: -40° to +55°C Size of Probe: 1" diameter x 12" long Weight: 1 lb. Temperature Compensation: 2% per °C Electrodes: 316 Stainless Steel

WQ401 Dissolved Oxygen Sensor
 

Output: 4-20 mA Range: 0-100% Saturation, 0-8 ppm, temperature compensated to 25°C Accuracy: ±0.5% of full scale Maximum Pressure: 40 PSI Operating Voltage: 10-36 VDC Current Draw: 15.5 mA plus sensor output Warm Up Time: 10 seconds minimum Operating Temperature: -40° to +55°C Size of Probe: 1 1/4" diameter x 11" long Weight: 1 lb. Membrane: 0.001 FEP Teflon (standard) Combined Error: 2% FS

WQ600 ORP/Redux Sensor
 

Output: 4-20 mA Range: -500 to +500mV Accuracy: 2% of full scale Maximum Pressure: 40 PSI Operating Voltage: 10-36VDC Current Draw: 0.2 mA plus sensor output Warm Up Time: 3 seconds minimum Operating Temperature: -40° to +55°C Size: 1" diameter x 10 1/2" long Weight: 1 lb.
