Key Features

  • Specifically designed for use with sticky gas sensors
  • Protects sensor and interior of enclosure from water and dust
  • Ideal for wash down, water spray, wet environments or outdoor applications
  • Factory installed
  • Comes with a Calibration Adapter Slide Cap for accurate calibration
  • The Calibration Adapter Slide Cap is a contrasting colour so it is easier to remember to remove it after calibration


A specially designed, optional Splash Guard that is factory installed at the time of order. It is specifically designed for CETCI gas detectors that have a sticky gas sensor and need protection in wet and/or wash down environments such as frequent equipment cleaning, sanitization or outdoor applications. 

Sticky gases like Chlorine, Chlorine Dioxide, Hydrogen Chloride, Hydrogen Cyanide, Ozone and Phosphine can be difficult to monitor because they adhere to many types of surfaces. Option -SN Splash Guard is made of a proprietary material that does not attract the sticky gas, allowing it to reach the sensor during normal operation.

The Splash Guard comes with a specialized Calibration Adapter Slide Cap, made of the same material that can be easily attached to the end of the guard during the calibration process. To ensure a successful calibration, this cap must be used, along with a Teflon lined tube so the sticky gas doesn’t adhere to the tubing and cause an inaccurate calibration. The length of the Teflon tubing should be no more than 61 - 91 cm / 2 - 3 ft so the gas flow concentration doesn’t lessen over the distance from the gas cylinder to the sensor.

NOTE 1:The Calibration Adapter Slide Cap MUST be removed during normal operation so the size of the opening to the sensor is adequate for measuring any potential gas in the area.

NOTE 2: If a splash guard is required for cGas Detector model CGAS-D-LCO-NO2, must use Option -SN.
