Portable thermohygrometers show versatility

Two new compact thermohygrometers provide users with versatile, portable solutions for temperature and humidity monitoring.

Testo has recently launched two new compact thermohygrometers that provide users with versatile, portable solutions for temperature and humidity monitoring.

Both instruments are supplied with a wide range of probes and accessories making them ideal for humidity monitoring in many areas including heating, ventilation and air conditioning, laboratories, process engineering and food production and storage.

The Testo 625 is an ideal entry level instrument for measurements of temperature, humidity and dewpoint.

Thanks to its detachable probe, the Testo 625 can be used to monitor hard-to reach points in air conditioning and heating system ducts or in remote rooms or storage areas, in fact, anywhere you need to be two places at the same time or only have one hand free to work.

The Testo 625's temperature/humidity probe can be used two ways: either attached to the instrument or connected via a probe handle and cable (optional accessory).

Additionally, an optional wireless temperature/humidity probe is available.

The clear backlit display can be switched between relative humidity, wet bulb and dewpoint at the touch of a button.

The Testo 635 is a high accuracy humidity and a temperature measuring instrument that offers a host of features to satisfy demanding requirements.

The Testo 635 is built on Testo's internationally patented humidity probe which has been proven to give reliable long-term measurement results in international laboratory tests.

A wide range of probes are available including air humidity, air temperature, dewpoint, material moisture, surface temperature and absolute pressure.

As well as cable connected probes, the Testo 635 can also be used with a range of wireless probes for temperature or humidity measurements (requires optional wireless module).

Easy to follow menus allow users to quickly navigate through the instrument's functions.

For ease of use, users can switch between two user profiles for "long-term" and "material moisture" measurements.

The Testo 635 is a robust instrument that is both durable and easy to use.

For example, the housing material (IP54) offers built-in protection against dirt and impact and the instrument features a carrying strap and magnets on the back panel for attachment at the measuring location.

The Testo 635 offers users two convenient documentation options - print out on-site or analysis and documentation on a PC.
