Sensor launched to measure volatile organic compounds

The new p-type metal oxide sensor, produced by Alphasense, is a broadband total volatile organic compound (VOC) detector with a range of 0–100 ppm (isobutylene) and 10–50 ppb detection limit, depending on the VOC

The new VOC sensor will be of particular interest to manufacturers and developers of instruments and monitoring systems for applications such as process monitoring, occupational safety, leak detection and environmental monitoring. Typical VOCs measured by the sensor include solvents, sterilants and petrochemicals.

Arthur Burnley, Director at Alphasense, said: “This new class of metal oxide sensor will complement our existing range, which also includes PIDs, offering a lower cost alternative that is unaffected by humidity and has low drift.

“There are many factors affecting the choice of VOC sensor. These include target gases, measurement range, sensitivity, power requirement, over gas limit, environmental conditions, response factors, possible interferences and budget. Consequently, there is no one sensor that meets all needs, so we have developed different technologies and different variants for each technology, so that customers can choose the sensor that best meets their requirements.

“However, there is one sensor requirement that is common to all customers and that is reliability; which is why Alphasense invests heavily in product development and a rigorous automated test and validation system. As a consequence, we are able to boast the lowest warranty returns in the industry.”
