Recommended for gas detectors with sticky gas sensors (Cl2, O3, HCl) installed in wash down or wet environments
This specially designed Splash Guard is an optional accessory that can be added to CETCI gas detectors that have a sticky gas sensor and need protection in wet and/or wash down environments, such as commonly occurring equipment cleaning, sanitization or outdoor applications.
Sticky gases such as Chlorine, Ozone and Hydrogen Chloride can be difficult to monitor because they adhere to many types of surfaces. For example, our conventional Splash Guard is made of a material that adsorbs sticky gases which blocks the flow of gas from reaching the sensor. If used, this would produce inaccurate or no gas measurement readings. This new Splash Guard for sticky gases 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.
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.
