testo 905-T2 – surface thermometer with a large measuring range

The measuring device was specially developed to enable precise temperature measurement on a wide variety of surfaces. With its spring-loaded thermocouple probe, it is particularly suitable for demanding measurement tasks in the heating, plumbing and refrigeration trades, for example when measuring valves or pipes. Anyone who appreciates fast and reliable results will find a practical and robust solution here compared to similarly equipped products such as the testo 810 – Infrared thermometer.

Performance features and special features

Thanks to its design with an adaptable measuring head, this surface thermometer achieves particularly short response times. It can also be positioned perfectly on uneven surfaces without the result being distorted by tilting. The short-term measurement up to +500 °C creates a remarkably wide range of applications. The device is also very easy to use: a rotatable display makes it easy to read the measured values and an automatic switch-off function after a long period of inactivity supports everyday routine operation. Similar devices, such as the testo 810 – Infrared thermometer, also offer high precision, but this model scores points with its spring-loaded probe, especially in situations where the surface is rough, uneven or difficult to access.

Detailed features

– Measuring range: -50 to +350 °C (briefly up to +500 °C)
– Accuracy: ±1 °C ±1 % of the measured value
– Response time: t99 = 5 seconds
– Resolution: 0.1 °C
– Weight: 80 g
– Dimensions: 220 x 40 x 70 mm (LxWxH)
– Sensor length: 150 mm (tip 40 mm)
– Power supply: 3 AAA microcells (battery life approx. 1000 hours)

In addition, the housing is made of durable ABS and can be used at ambient temperatures between 0 and +40 °C. With a storage range of -20 to +70 °C, the device is well protected even in harsh operating environments or on the move. As a CE 2004/108/EEC-approved product, it meets important safety standards that are required in many industrial sectors.

Typical areas of application

In heating technology, the precise surface thermometer is indispensable for monitoring boilers, pipes and hot water systems, for example. It has also proven its worth in the plumbing trade for checking fittings, flange connections and valves. As the thermocouple tape reacts quickly to temperature fluctuations, users benefit when maintaining hot and cold water pipes when the temperature changes in a matter of seconds.
– Measurement on metallic surfaces of various pipe dimensions
– Temperature testing on valves, flanges and screw connections
– Function check on boilers and heat exchangers
– Quick diagnosis of refrigeration systems (e.g. refrigerant pipes)

With its large measuring range, the device can record a wide range of temperatures, for example at the outlet of a heat exchanger or during quality control in manufacturing processes where short-term peak temperatures occur, such as in metal processing.

FAQs

How quickly does the thermometer react to temperature changes?

The model takes around 5 seconds to record 99% of the actual measured value (t99 value). This means that even rapid temperature fluctuations can be reliably detected.

Can the device be used continuously at high temperatures?

Continuous operation is intended up to +350 °C. Up to +500 °C is possible for short periods if the measuring phase only lasts one to two minutes.

Is the thermometer suitable for outdoor use?

Thanks to its robust housing and wide storage temperature range, the device can be used outdoors. However, the operating temperature should not permanently exceed or fall below 0 to +40 °C.

Which batteries are required and how long do they last?

Three micro cells (AAA) are used, which are expected to last around 1000 hours under normal use. This simplifies replacement and eliminates the need for a mains connection.

How do I clean the probe after using it in a dirty environment?

Careful cleaning with a soft, damp cloth is usually sufficient. For heavier soiling, we recommend using mild cleaning agents without aggressive solvents to avoid damaging the thermocouple.

Summary

This surface thermometer stands for measuring speed, ergonomics and an exceptionally wide range of applications. The combination of spring-loaded probe and convenient rotary display ensures precise and easy-to-read values in everyday use, even under challenging conditions. Whether for quick temperature checks on hard-to-reach pipes or for regular servicing of heating and cooling systems – the device impresses with its reliability and short response times. Anyone who needs a robust and versatile temperature measurement and at the same time wants to benefit from an automatic switch-off function and CE-compliant design will find this a future-proof solution in professional measurement and testing technology.
