Precision measurement instruments for emissions, flue gas, thermal imaging and industrial monitoring. Available through Gastech.

Nearly seven decades of measurement engineering distilled into instruments that are consistently, reliably right.
Testo has been engineering precision measurement instruments since 1957. That’s nearly seven decades of refinement, and it shows in the instruments they make. In flue gas analysis, emissions monitoring, thermal imaging and industrial measurement, Testo is the name professionals reach for when accuracy matters.
The Testo range available through Gastech covers more ground than most people realise. The testo 350 is the benchmark for industrial emissions measurement. It’s a modular analyser that measures up to six gases at once, including CO, NO, NO2, SO2, H2S and CO2, built for power stations, industrial furnaces, gas turbines and large combustion processes where emissions compliance is a legal requirement. The testo 340 brings that industrial capability into a compact, portable analyser, with up to four gas sensors, for commissioning and servicing industrial burners, stationary engines and thermal processes. For heating and HVAC work, the testo 300 offers a large touch display, instant start up, and reports created on site and emailed straight away.
Beyond emissions, the Testo thermal imager range helps maintenance teams find thermal faults in electrical and mechanical systems before they become failures. The cameras are used across mining, oil and gas, utilities and industrial maintenance to reduce unplanned downtime and extend asset life, with images analysed in testo IRSoft or on a phone through the Testo apps.
Gastech is an authorised distributor for the full Testo range, providing sales, service, calibration and technical support from our offices in WA, NSW and QLD.
