The meter has nine user selectable display pressure units: in H2O, mbar, hPa, bar, Pa, kPa, mm H2O, torr and psi. Flexibility is enhanced as additional probes can be connected via 2 user defined probe sockets.

Testo 535 CO2 carbon dioxide meter

testo 535 CO2 (Carbon Dioxide) Monitor

The testo 535 measures CO2 for indoor air quality (IAQ) surveys. Poor air quality in rooms can lead to tiredness, lack of concentration and illness (Sick Building Syndrome)

testo 535 CO2 Carbon Dioxide  Meter

testo 317-3 Carbon Monoxide (CO) Stick

The testo 317-3 CO meter detects the presence of carbon monoxide (CO) in ambient air from gas furnaces, water heaters, and other appliances or equipment. Signals the user of dangerous gas concentrations with both visual and audible alarms.

Teswto 545 light meter

testo 545 Light Meter

The testo 545 light meter checks lighting levels and can quantify the luminous intensity in the workplace, hospitals, offices or schools.  It can verify if the lighting meets specific minimum guidelines and provides information on the uniformity of the lighting.


Digital Manometers

testo 635 Thermohygrometers

testo 625 Thermohygrometers

The testo 625 simultaneously displays temperature and %RH or dew point - suitable for monitoring work-area comfort conditions, IAQ parameters, HVAC and manufacturing areas requiring humidity and temperature control.

Probe configuration options include using the probe head on a cable and extended handle, and a wireless probe.

testo 512-Series Portable Digital Manometers

The testo 512 series has 4 different pressure & velocity meters.

  • display 6 switchable units: hPa/mbar, mm H2O, mm Hg, psi, in H2O, in Hg

  • 2 additional probes can be connected


Testo 465 non-contact optical tachometer

testo 465 non-contact optical tachometer

The testo 465 is a non-contact optical tachometer. Measures rpm by attaching a reflector to the object to be measured, pointing the red light beam at the reflector and measuring. Max/Min and last reading.

testo 470 dual-function non-contact  optical/mechanical RPM tachometer

testo 470 Dual-Function Non-Contact Optical/Mechanical Contact RPM Tachometer

The testo 470 is a combination of optical & mechanical rpm measurement. Optical measurements become a mechanical measurement by simply attaching an adapter for a probe tip or surface speed disk.

Testo 476 Pocket Stroboscope

testo 476 Pocket Strobe™

The testo 476 Pocket Strobe™ handheld stroboscope measures and checks rotation and vibration movements. It facilitates the measurement of very small objects or in hard-to-access places.
