Temperature Measuring Instruments

Where it all began ...

Testo started 40 Years ago as one of two manufacturers of digital thermometers in the world. Since then several hundred thousand thermometers from Testo are measuring temperature around the world.

The early experience led to a vast knowledge of all measurement applications. Today Testo is still manufacturing more different types of instruments and probes than any other company in the world.


Handheld Thermometers

A wide wvariety of different thermometers for every application and budget.
 
The Testo 105  Testo has changed the perception of NTC thermomters with the T 105. A wider range  
than ever at an new price level.
The Testo 110  Inexpensive but very accurate NTC Thermistor Instrument (Range of -50° to 150°C  
(-60° to 300°F))
The Testo 720  Precise yet affordable with a wide temperature range of : -100° to 800°C (-150° to 1470°F)
The Testo 950 The Reference Class: Most Accurate Thermometer from testo. Range: -200° to 1760 °C  
(-328° to 3200°F)
The Testo 901 The widest selection of probes for the instrument with the widest temperature range of:  
-115° to 1370 °C (-180° to 2500°F)
The Testo 925  Quick temperature measurements for applications in all sectors of industry. Range: -50° to  
1000°C (-60° to 1850°F)

Handheld Infrared Thermometers

Testo offers two different concepts for your infrared temperature measurement needs. With the Testo 925 a "traditional" thermometer´s probe program is expanded by an infrared probe. The Testo 850 instruments are pure infrared thermometers.
 
The Testo 925  Quick infrared temperature measurements for non-contact temperature measurement.  
An infrared probe allows distance measurement with the range of -20° to 260°C (-4° to 500°F)
The Testo 850 A one-piece measuring instrument for non-contact temperature measurement. Available  
with LED or laser sighting. Range: -30° to 400°(22° to 752°) 
 

Temperature Loggers

Temperature loggers from Testo electronically record temperature over long periods of time and download to a PC. Two performance/price levels are available.

The Testo 171 Series High end mutli-channel datalogger with a battery life up to 5 years. Family of 1 to 4  
channel temperature dataloggers.Range: -35° to 70°C (-50° to 158°F)
The Testo 175 Series Low cost datalogger with three different types to fit applications.
