Company Information

Optec Environmental was born from an opportunity to design and manufacture our own low cost particulate monitor, the Parmon 1025.

The Parmon particulate is based on a MCERTS optical sensor, together with our own developed software that allows you to view, plot and download your particulate data from a cloud based server.

The engineers at Optec Environmental have been in this industry for many years, specializing in the measurement, maintenance and repairs of air quality monitoring analyses.

With the establishment of Optec Environmental, we are taking this one step further. We have designed and manufactured our own, truly LOW COST particulate monitor to measure pm1, pm2.5, pm4 and pm10. Our monitor is MCERTS approved compares with the cost of dust buckets to monitor particulate matter.

Our name represents this new development in our history and literally means OPtical TEChnology.

Caring for our environment through optical technology.
