The Sensorex S465 and S420 Series’ advanced sensor technology delivers accurate measurement over a range of 0-14 pH or +/-1000 mV for ORP. Sensors use Sensorex’s proprietary polymer sensor reference gel for longer service life. Both series employ a 1/2-inch NPT connection for easy installation. The S465 models are supplied with a BNR connector, while the S420 models are available with a 30-inch or 10-foot cable length. Advanced signal shielding reduces noise for more accurate communication with process control systems. | (714) 895-4344
