The CO<sub>2</sub> probe (in conjunction with the appropriate measuring instrument) helps you to detect carbon dioxide in indoor room air.

Savršeno za zahtjevne primjene: Brzo reagirajući površinski senzor s termoelementom s oprugom pruža pouzdana mjerenja – čak i na temperaturama do +500 °C.

You can carry out all the necessary tests on gas heating systems as well as water and gas pipes with the testo 312-4 electronic differential pressure measuring instrument. Preset measuring processes, for example for load and tightness tests as well as serviceability testing on gas pipes, provide you with ideal support for your work.

Professional pressure/leak detector for installation, maintenance and service of gas and water pipes. Specially designed to carry out reliable leak tightness checks, load tests, serviceability tests, temperature measurements in accordance with existing rules and regulations.

Testo proudly presents the world’s first portable exhaust gas analyzer for diesel ship engines: the testo 350 MARITIME! The groundbreaking exhaust gas analyzer measures emissions at diesel ship engines in compliance with MARPOL Annex VI and NOx Technical Code 2008.

You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.

The high-precision testo 521-1 differential pressure measuring instrument is ideal for accurate differential pressure measurements in air conditioning and ventilation technology, for instance for pressure drop on filters, checking fans and extractors or for Pitot tube measurements.
