New PPM and PPB wide range sensors aimed at lower explosive limit of VOCs for environmental and safety applications

In a key strategic move designed to further increase its share of the global photoionisation detector (PID) market, ION Science has launched exciting new MiniPID 2 parts per million (PPM) and parts per billion (PPB) Wide Range (WR) sensors which can be incorporated into both fixed and portable instruments for the detection of volatile organic compounds (VOCs).

ION Science’s new MiniPID 2 PPM WR sensor offers a measurement range up to 10,000 ppm and is aimed at detecting the lower explosive limit (LEL) of VOCs, as well as leak detection and repair (LDAR) applications. The MiniPID 2 PPB WR sensor boasts a measurement range of 20 ppb to 200 ppm making it suitable for industrial health and safety and fugitive emissions.

Pete Morris, ION Science’s Business Unit Manager for Sensors comments: “During the past few years, we have focused on expanding our range of sensors for the accurate and reliable detection of VOCs. The two new MiniPID 2 WR models will plug the remaining gap in our portfolio, open up new global markets and allow us to target previously untapped business.

He adds: “Many VOCs have an LEL above 4000 ppm and LDAR method Environmental Protection Agency (EPA) 21, which is defined as ‘determination of volatile organic compound leaks’, dictates you have to measure up to 10,000 ppm. Before launching the MiniPID 2 PPM WR sensor we couldn’t fully access these markets.

“In addition, prior to introducing the MiniPID 2 PPB WR we did not have a sensor optimised for detecting VOCs in industrial environments that have threshold levels between 40 and 200 ppm. It will also help our customers adhere to legislation in the USA which requires fugitive emission measurements of VOCs, including benzene, up to 200 ppm.”

Like all ION Science’s MiniPID 2 sensors, the new WR models offer patented humidity resistance and an anti-contamination design aimed at fast detection of VOCs within even the most challenging environments.

The sensors also incorporate ION Science’s next generation 10.6 eV long-life lamp, which provides exceptional stability and long-term performance, ensuring robust and repeatable sensing for 10,000 hours. Plus, the PPM WR sensor boasts a lamp out diagnostic.
