Screw in, connect, start measuring – The most compact and fastest of our measuring devices determines various properties of binary and virtually binary gas mixtures.
The gasQS™ static precisely determines heat conductivity using a microthermal sensor. For binary gas mixtures (e.g. biogas), it can derive the percentage of the gases as well as calculate various gas properties such as calorific value and density with high accuracy.
Only minimal interventions into the pipe system and no exhaust line required

A binary gas mixture (BG) is a mixture of two components such as methane and carbon dioxide. These are often found in applications with biogas plants.
Thanks to its high sensitivity, the sensor is highly suitable for tracing changes in gas nature in the case of gas mixtures with more than two components
The gasQS™ static as a process instrument experiences wear from the
conditions of the process in which it is installed. Temperature cycles,
electronic component tolerance shift including the sensor chip and
contamination build up over time on the sensor chip will all contribute to
affecting the accuracy of the instrument. It should therefore regularly
undergo, at a minimum, a calibration check if not a recalibration. But how often?
gasQS™ static does not have specified due dates for calibration. Mems AG designed the device from the very beginning in such a way that the above influences have the smallest possible effect on the long-term behavior of the sensor.
The entrance to the measuring chamber is protected by a double-mesh filter against the entry of dirt particles. The chip sensor has passed its long-term test in several million passenger cars as a mass flow meter of the intake air, but also in household gas meters, over more than 6 years, no reduction in performance of the sensor could be detected. When installed correctly, i.e. in upside-down position, no contamination of the chip, which would impair its function, is to be expected even in long-term operation with non-condensing gases. All electronic components meet the requirements of the strict standards of the automotive industry, so no premature aging effects should occur from this side either.
Mems suggests that gasQS™ static undergoes a calibration check every two years. However, based on the application conditions, and perhaps company quality procedures, each customer must determine when they need to send in an instrument for recalibration.
The easiest way to check is to use one of the gases listed on the "Calibration Documentation" to compare the measured values obtained with those of the initial test. If this is not possible, Mems is happy to take on this task for its customers.
