Keep a keen eye on air temperature and relative humidity figures in your workplace with this Testo probe. It transmits values to measuring instruments in the 440 series via a wired connection, and the 1.4m cable gives you plenty of room for convenient evaluation from a distance. Thanks to its universal handle, you won't have trouble linking it to your probe heads. It also comes with a handy button that you can press to store measurement data on the instrument, so you can monitor periodic changes as they take place.

• Light weight of 160g for easy handling during operation
• Broad operating temperature range of -5°C to +50°C for use in demanding settings

• Coldrooms
• Food production industry

• Proven quality from Testo: you can depend on reliable measurement results, because the humidity/temperature probe is equipped with our high-precision, long-term stable humidity sensor. This measures the humidity with an accuracy of ± (0.6% RH + 0.7% of m.v.) in the range between 0 and 90% RH and is traceable to international humidity standards, such as ILAC, PTB and NIST.

• Use the fixed cable on the handle to connect the humidity/temperature probe to the measuring instrument (please order separately).

• Particularly useful: store individual readings directly in the measuring instrument by pressing the button on the humidity/temperature probe. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. These trends enable you to evaluate changes in the data.

• Space-saving: more applications, less equipment

• Endlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space.

• Order the Bluetooth® handle to make it more convenient to carry out your measurement and guarantee less cable clutter in the case. This transmits the readings to the measuring instrument from a distance of up to 20 metres. If the humidity sensor needs to be replaced in the distant future, you can change the probe head.

Intelligent calibration concept

You will get exceptionally accurate measurement results with the digital humidity/temperature probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.

This unit has compact dimensions of 290 (L) x 50 (W) x 40mm (H), so it will take up minimal space in your toolkit.
