Sensor Cross Sensitivity
Read more about Sensor Cross Sensitivity Cross sensitivity is a sensor’s reacÂtion to other gases which can interfere with how the sensor reacts. Exposing a sensor to a gas that is not the target gas can cause an unwanted effect; this may be a positive response, negative response or inhibition. Positive Response A positive response means that sensors respond to not just the target gas but another gas as well.blog... Read More
Gas Sampling Tips
Read more about Gas Sampling Tips Using a pumped gas detector to sample the air inside a confined space is crucial to ensure worker safety. Before taking air samples using a portable gas detector, here are some tips to consider. Perform a bump test on the instrument before you begin Keep the tube length as short as possible. Allow sufficient time for air sample to reach the sensor (allow at least 4 seconds per meter of tubing) Remember to use Teflon tubing for reactive gases such as chlorine, ammonia, hydrogen sulphide and hydrogen chlorideblog...

Sensor Life Expectancy
Read more about Sensor Life Expectancy Given the importance of gas detection equipment, it's crucial to ensure that it is working correctly. Sensor life expectancy can vary depending on the gas that it is being exposed too. The sensors for more exotic gases(for example chlorine or ozone) tend to have shorter life spans than sensors monitoring the more common gases (Carbon Monoxide, Hydrogen Sulphide for instance). For example, standard Oxygen sensors usually last up to two years, with long-life options available. The sensors inside of gas detectors can be affected by various circumstances. - Ambient temperature - Humidity levelblog... Read More
