SR-W-MP75C Replacement MICROpeL Combustible (LEL) Sensor

Keeping your gas monitor running smoothly and accurately is a vital task that ensures your safety. By routinely checking your sensors to verify that they are responding to gas is crucial. If you find that your LEL sensor is failing calibration or responding slowly you should immediately replace it. Combustible sensors are often contaminated by various substances in the environment and weaken over time. If this occurs please replace your sensor immediately.

SR-H-MC Replacement MICROceL Hydrogen Sulfide (H2S) Sensor

Make sure your monitor is protecting you by routinely changing your H2S sensor. Hydrogen Sulfide is one of the most potent dangers in today's working environment. Always bump check to make sure you are getting accurate readings. If your sensor is slow to respond or doesn't respond at all then replace immediately. Changing the sensor is a fast and easy process, simply open your monitor, slide out the existing sensor, and plug in the new one. Once it is installed you will need to re-calibrate your instrument before use.

SR-W04-SF Combustible (0-100% LEL) Sensor (with heavy duty silicone filter)

One of the main problems with catalytic style combustible sensors is their penchant for becoming poisoned by various environmental contaminants. One of the most frequent contaminants is Silicone. Combustible sensors operate using two pellistors, one which is reactive to gas, and the other which is not. When the sensors come into contact with silicone it coats the pellistors and prevents the gas from reaching them. Once this has occurred the only solution is to install a new sensor. Symptoms of a sensor that has been poisoned is slow response to gas or no response. This special version is fitted with a heavy duty silicone filter that helps to prevent silicone from reaching the internals of the sensor. Use this sensor in environments that have a known concentration of silicone in the work environment.
