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 735-2 is a digital multi-channel thermometer that has a wide range of applications. This is hardly a surprise given that you can use it for virtually any type of temperature measurement such as core temperatures, air temperatures, surface temperatures, liquid media, etc. It is also perfect as a reference thermometer as it can measure with an accuracy of up to 0.05°C with a high accuracy Pt100 sensor. You can also connect three more external radio temperature sensors wirelessly, giving you a total of 6 measurement channels.

Wide range of sensors, accurate measurement results on up to 6 channels

The testo 735-2 professional thermometer has a sensor connection for a highly accurate Pt100 sensor and two connections for fast thermocouple sensors of type K, T, J and S. In total, you can connect 6 sensors, including 3 wireless radio sensors, to the instrument and show the values on the display. There is a wide range of insertion sensors, air temperature sensors, surface temperature sensors to help you make quick and accurate temperature measurements on a variety of surfaces and media.

The high-accuracy Pt100 sensor (0614 0235) for dip and insertion measurements has a system accuracy of 0.05 °C and a resolution of 0.001 °C. The testo 735-2 is therefore ideal for use as a reference thermometer.

The testo 735-2 temperature meter has a logging function

The accurate temperature meter testo 735-2 not only allows you to perform fast and accurate temperature measurements, it also allows you to log up to 10,000 measurement values, create up to 99 measurement locations and multiple user profiles. In addition, you can save individual measurement blocks or measurement series for each measurement location and select logging intervals between 0.5 seconds and 24 hours. The included software allows you to save and analyze measurement data in tabular or graphical form. Last but not least, you can use the optional wireless quick printer to print directly at the measurement site.

The testo 735-2 temperature meter is practical

The testo 735-2 can give you delta-T, min, max and average values and present them on a backlit display that makes them easier to read in dark environments and poor lighting conditions.

If you’re looking for a professional thermometer or temperature gauge, here’s a handy measuring set designed for insertion measurement. The instrument and the robust temperature sensor are extremely easy to use and also benefit from the intelligent calibration concept, which means you only send in the sensor part and keep the handle and the instrument when it is time to calibrate.

This measurement kit includes the testo 440 multi-instrument. It can be connected to a wide range of digital sensors, testo SmartProbes and many other temperature sensors. Clearly structured measurement menus for duct/vent volume flow, k-factor, turbulence degree, cooling/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.

All sensors that work with the testo 440 and testo 440 dP can also be used with the reference meter testo 400.

Included in delivery

• testo 440 for ventilation and indoor climate, 3 pcs. AA batteries, USB cable and factory protocol.
• Digital plug-in sensor with fixed cable, measuring range -100 … +400 °C, accuracy up to ±0.15 °C, sensor length 200 mm.
