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

Everything the professional needs for testing gas pipes: in addition to the testo 324 leakage measuring instrument, including system case with feeding unit and other accessories, you get an infrared printer for measurement data documentation on site, along with the testo 316-EX gas leak detector.

Perfect for demanding applications: The fast-reacting surface sensor with spring-loaded thermocouple band provides reliable measurements - even at temperatures up to +500 °C.

Set with flue gas analyzer testo 320  (with H2-compensated CO measurement cell and Bluetooth), modular 300 mm flue gas probe, combustion air probe and mains unit

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.

Temperature measurements at radiators; flue gas parameter and pressure measurements at burners; CO measurements in the ambient air: the testo 320 allows you to carry out all measurements in and around heating systems with only one measuring device.

The ideal equipment for heating engineers: with this testo 320 flue gas analysis set, you can carry out your measuring tasks on heating systems quickly and efficiently. Use the flue gas analyzer to measure flue gas, draught, pressure, ambient CO and CO2, differential temperature and also detect gas leaks. In the set you also get practical accessories to help you with 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.

The high-precision testo 521-2 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.

Differential pressure measuring instrument 0 to 2.5 hPa

Ideal for checking pressure in sensitive industrial processes: the testo 526-1 high-precision differential pressure measuring instrument with a measuring accuracy of &plusmn; 0.1% of final value. It also has two probe inputs for additional pressure and temperature probes.

The testo 526-2 high-precision differential pressure measuring instrument is ideally suited for checking pressure in sensitive industrial processes, thanks to a measuring accuracy of &plusmn; 0.05% of final value. Two additional pressure and temperature probes can also be attached.

The testo 645 humidity/temperature measuring instrument automatically indicates the measurement parameters of relative humidity, absolute humidity, dew point, degree of humidity, enthalpy and temperature at the touch of a button.
