  • free chlorine sensor

    Now Available with optional MODBUS/RS485 Interface

    Chlorine exists in different chemical forms in solution, including free chlorine (hypochlorite ion and hypochlorous acid) and combined chlorine. Free chlorine is the only form that can perform disinfection, so knowing free chlorine concentration is critical for applications like water and wastewater treatment. FCL free chlorine sensors from Sensorex provide a direct measurement of free chlorine in parts per million (ppm). Using field tested amperometric technology, our FCL sensors perform continuous monitoring without any additional reagents. With a direct 4-20mA analog or MODBUS/RS485 digital output, the FCL sensors can be used with any PLC or SCADA.
    • Direct free chlorine measurement in parts per million (ppm)
    • No reagents requried
    • Direct 4-20mA output or optional MODBUS/RS485

  • blind pH transmitter

    Now Available with optional MODBUS/RS485 Interface

    The EM802-EC is our most cost-effective solution for connecting our S8000 series Contacting Conductivity sensors to a PLC or SCADA system. This small electronic module functions as a blind transmitter with a 4-20mA or MODBUS/RS485 output. No additional instrumentation is required to condition the sensor signal to be read by your PLC or SCADA. It can also be used to pair Sensorex sensors with any controller that has a 4-20mA or RS485 input card. Easily connects to our CS8300TC Modular Contacting Conductivity Sensor Package to form a complete monitoring solution.
    • Blind 4-20mA or MODBUS/RS485 transmitter for connecting conductivity sensors to PLC or SCADA
    • Small form factor saves valuable panel space
