testo 735-1 - Highly Accurate Temperature Measuring Instrument

If you need a measuring instrument for accurate temperature measurement or you would like to measure the temperature in several locations simultaneously, the testo 735-1 is the ideal equipment for you. The wide selection of optional probes enables flexible use of the temperature measuring instrument, from calibrating stationary temperature probes to monitoring multi-point setups in the electronics, food, and pharmaceutical industries.

Your Advantages

With optional probes that measure core temperature, surface temperature and air temperature.
Up to three probes can be attached and three additional temperature probes can also be connected to the temperature measuring instrument by radio.
Accurate measurement up to 0.05 °C with Pt100 temperature probe (optional).
Display of min., max. and mean values and calculation of the differential temperature (Delta T).

What It's For & Who It's For

Applications (What It's For)

The testo 735-1 can deal with almost all measuring tasks. It is utilized in chemical laboratories for temperature measurement in aggressive media, for measuring temperature distribution in air conditioning cabinets and refrigerators, for calibrating stationary temperature probes, or in the food industry for measuring precise core temperatures.

Who It's For

This instrument is built for professionals operating in highly regulated environments where extreme accuracy is non-negotiable. This includes quality assurance managers, laboratory technicians, refrigeration specialists, and industrial calibration experts who need a dependable working standard.

Core Functionality

6-Point Measurement: Measure surface, air, and core temperature in up to six locations at the same time. The instrument has one input for high-precision Pt100 probes, two inputs for fast thermocouple probes (Types K, T, J, S), and supports up to three wireless radio probes (up to 20m range).
Unmatched Precision: Achieve system accuracy of up to 0.05 °C with a resolution of 0.001 °C using the optional high-precision Pt100 immersion/penetration probe.
Smart Analytics: The display automatically shows min/max/mean values and calculates the differential temperature (Delta T). An acoustic alarm sounds when freely defined limit values are breached.
Rugged & Compliant: The backlit display enables easy reading in dark surroundings. The housing is IP65 waterproof, tested in accordance with EN 13485, and holds international HACCP certification.
On-Site Printing: Compatible with the optional testo fast printer for printing current values, min/max limits, or cyclical measurement series directly on the job site.

Tradie Pro Tip: Remember, the testo 735-1 is a highly customizable base unit and requires a separate probe to function! If you're doing compliance testing for commercial refrigerators or labs, adding the optional Testo fast printer is a game-changer. Handing your client a physical printout of the cyclical data instantly proves your work is flawless and up to code.

Delivery Scope

The testo 735-1 temperature measuring instrument (3-channel) with an acoustic alarm, including calibration protocol and batteries.
Caution: The instrument can only be commissioned with a probe. These are available separately.

Overview of Applications

Calibration of Stationary Temperature Probes

For extremely accurate measurements: a system accuracy of 0.05 °C is achieved with a resolution of 0.001 °C using the plug-in high-precision Pt100 immersion/penetration probe (0614 0235). The testo 735-1 can be used universally as a working standard.

Temperature Distribution in Refrigerators & Conditioning Cabinets

3 probe connections for plug-in probes + up to 3 radio probes can be connected simultaneously.
A wide variety of probes are possible to map entire cooling zones.
Display, saving, and printout of Delta T, min., max., and mean values on-site.

Measurement of the Heating of Electronic Components

Gain the advantage of a large range of available probes, including surface probes in the most varied shapes. Calculate and display Delta T to evaluate thermal load precisely across complex circuit boards.

Temperature Measurement in Chemical Labs & Cosmetics

Leverage the extreme Pt100 accuracy (0.05 °C) to monitor sensitive mixtures. The IP65 rating ensures the instrument meets the strict cleaning requirements of the pharmaceutical and cosmetic industries.
