The new generation of climate instruments. Smarter. Faster. Better.

Smarter
The versatile testo 400 climate instrument and the wide range of precision sensors were developed with a single goal in mind: to make all measurement tasks in the field of ventilation easier and less complicated than ever before.

Faster
With testo 400 you can perform tasks that were previously only possible with a PC and software – directly on site with just one measuring instrument!

Better
With the testo 400 you always have your own personal assistant with you. The more demanding the measurement, the more support you get from the help functions in setting, measuring and evaluating the results.

Advantages of the testo 400

• Smart user support with ready-made measurement menus and measurement value analysis with traffic light principle – for error-free measurements.
• Manage all relevant customer data including measurement points directly in the instrument – work efficiently and directly at the measurement site.
• Finish the assignment by creating a report with full documentation, including photos, comments and your own logo directly on the site – get to the next job faster.
• The sensor can be changed without restarting the instrument – easy handling without losing time.
• The digital sensors can be calibrated completely independently of the measuring instrument. This means that you can continue to use the instrument with other sensors.
• The handy service bag provided includes molded slots for specific sensors and accessories.

So, as a consultant, expert or service technician in the ventilation sector, the testo 400 will help you carry out your measurement tasks quickly and efficiently. Relevant quality parameters in industrial production and manufacturing processes can also be checked reliably and accurately with the testo 400.

If you need a measuring instrument for accurate temperature measurement or if you want to measure the temperature in several places at the same time, the testo 735-1 is the perfect equipment for you. The large selection of optional sensors enables flexible use of the temperature measuring instrument, for example to calibrate stationary temperature sensors, in the electronics and food industry or in laboratories.

Measures surface, air and core temperatures – in up to 6 locations simultaneously

Whether your work involves core temperatures, surface temperatures or air temperatures – choose the temperature sensors that are right for you from our wide range of sensors and measure the temperature at up to six locations simultaneously with the testo 735-1. The temperature meter has one input for connecting a highly accurate Pt100 sensor and two inputs for connecting K, T, J and S thermocouple sensors.

Also benefit from wireless measurement data transmission via radio. The optional radio module allows you to receive readings from up to three additional radio temperature sensors. The radio sensors transmit temperature values to the instrument over a distance of up to 20 meters (line of sight).

Accurate temperature measurement with Pt100 sensor

With Pt100 technology, you can achieve highly accurate temperature measurements with the testo 735-1. High precision dip/insert sensors achieve a system accuracy of up to 0.05°C with a resolution of 0.001°C. The temperature measuring instrument is therefore ideally suited for use as a working reference when calibrating stationary temperature sensors.

The testo 735-1 temperature meter meets several different standards

The testo 735-1 not only displays temperatures in real time. It also shows min/max and average values on the instrument display. When two temperature sensors are connected, the temperature meter calculates the differential temperature and displays it as delta-T. In addition, an audible alarm sounds when the readings fall below or exceed your set alarm limits. The display illumination enables clear reading of measured values even in dark environments. The testo 735-1 is also waterproof according to protection class IP65, is tested according to EN 13485, is HACCP compliant and has international HACCP certification.

Documentation of measurement data with Testo’s high-speed printers

If you need to document measured temperature values, these can be easily transferred from the testo 735-1 to the testo rapid printer via Bluetooth.
Also use the handy cyclical print function. It allows not only the printing of individual measurements but also a whole series of measurements at freely adjustable intervals (e.g. once a minute). We recommend using the testo 735-2 to save, document and archive measurement data. This temperature meter also has a built-in memory and PC software.

The testo 905-T1 has a wide measuring range from -50 to + 350 ° C and can even measure up to + 500 ° C for a short time (1 to 2 minutes). The hard-wired Type K thermocouple sensor makes this possible. In addition, the insertion thermometer is characterized by its short response time. The thermocouple sensor reacts very quickly, especially in water (or other liquids). The insertion thermometer is therefore ideal for measurements in liquid substances in laboratories, chemical and pharmaceutical fields.

In addition to dip/insert measurement with the long, pointed probe in liquids and soft or powdery substances, you can also use it in ventilation ducts to measure temperature.

A really user-friendly thermometer

The testo 905-T1 insertion thermometer is easy to use and very user-friendly. You can easily read the measured values on the display, including the fact that the display can be rotated. This is particularly handy as it means you can easily view the readings from many different angles.

Included in delivery

The testo 905-T1 insertion thermometer, attachment clips and batteries.

The testo 905-T2 thermometer can measure surface temperatures reliably and impressively fast even on uneven surfaces. The measuring head with the spring-loaded thermocouple is what makes this possible. This efficient surface temperature measuring instrument is therefore suitable for various applications in the heating, plumbing and cooling industry (e.g. measurements on pipes or valves).

Another advantage of the temperature sensor (type K) is that its spring-loaded thermocouple absorbs the temperature of the measured object very quickly. Thus, the temperature meter achieves high accuracy and an impressively fast response time. The testo 905-T2 for measuring surface temperature also impresses with its wide measuring range from -50 to +350 °C. Measurements up to +500 °C are also possible for a short period (1 to 2 minutes). The large measuring range means that the thermometer has many different applications, such as in heating, plumbing or refrigeration technology. The thermometer is particularly well suited for temperature measurements on pipes, as its thermocouple probe can easily handle uneven surfaces.

Extremely user-friendly surface temperature thermometer.

The testo 905-T2 for measuring surface temperature is really easy to use: you can comfortably read the measured values on the clear display. They are also easily readable from different angles. This is because the instrument is rotatable and can be adjusted to your point of view. If you forget to turn the thermometer off, it will automatically turn itself off after about 10 minutes of non-use.
