The testo 103 food thermometer is just a little over 11 cm long, which makes it the smallest folding food temperature thermometer in its class. In fact, it’s so small it fits in any shirt or trouser pocket, so it’s always accompanying you whenever you need it. The probe can also be folded while not in use, to avoid any damages.

The testo 103 food thermometer – ideal for food safety inspections  

The testo 103 food temperature thermometer can be used everywhere where food is sold, stored or processed. It is ideal for checking incoming goods, catering services, canteens and commercial kitchens, as well as cold storage rooms and supermarkets, and for ensuring that temperatures are kept and quality and hygiene standards are met. 

The sleek food thermometer with rugged sensor tip makes it ideal for carrying out spot checks on liquid and semi-solid media where it leaves virtually no trace. 

It can also measure the core temperature of foodstuffs when the probe has been folded out at an angle of only 30°. This is particularly convenient – and often necessary – as it is not always possible to carry out measurements at an angle of 180° when checking food in certain storage spaces or when it is piled high in boxes or on display. 

When you have finished carrying out your checks, simply fold the probe away and pop the thermometer back into your pocket until you need it again.The testo 103 food probe thermometer is not only HACCP compliant and EN 13485 certified but also splash water protected making it ideal for use in the food sector.

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

Temperature Measuring Instrument - Testo 735-1
Model No: Testo 735-1 Part No: 0560 7351

The multichannel temperature measuring instrument testo 735 can measure the surface, air and core temperature of a whole range of media and thus can be used for measuring temperature distribution in air conditioning cabinets and refrigerators, etc.

  1. Highest precision over the entire measuring range thanks to system adjustment
  2. System accuracy up to 0.05 °C
  3. Audible alarm (adjustable limit values)
  4. Cyclic printing of measurement values, e.g once per minute
  5. Protection class IP65
  6. Certified according to EN 13485


The testo 735-1 temperature measuring instrument can deal with almost all measuring tasks. That is because the comprehensive selection of optional probes enables reliable temperature measurement in a variety of areas. This means you can for instance use the measuring instrument 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 core temperature. 
 
Measure surface, air and core temperature – in up to 6 locations at the same time. Whether your work involves core temperatures, surface temperatures or air temperatures – choose the temperature probes that are appropriate for you from our large selection of probes and measure the temperature in up to six locations at the same time with the testo 735-1 temperature measuring device. 
 
The temperature measuring instrument has one probe input for attaching high-precision Pt100 probes and two inputs for attaching fast thermocouple probes of the K, T, J and S types. Take advantage of wireless measurement data transfer by radio as well. The optional radio module means you can receive readings from up to three further optional radio temperature probes on the testo 735-1. The radio probes send the temperature values to the temperature measuring instrument over a distance of up to 20 meters where there are no obstructions. Wireless measurement enables you to avoid damage to cables or hindrances to handling. 
 
Accurate temperature measurement with Pt100 temperature probe, Pt100 technology enables you to achieve very accurate temperature measurements with the testo 735-1. The high-precision Pt100 immersion/penetration probe (optional) thus achieves system accuracy of up to 0.05 °C with a resolution of 0.001 °C. The temperature measuring instrument is therefore ideally suited to use as a working standard for calibration of stationary temperature probes. 
 
The testo 735-1 temperature measuring instrument offers great features and standard-compliant work.

The testo 735-1 temperature measuring device does not just display the temperatures currently being measured. Min./max. and mean values are also shown on the instrument display. When two temperature probes are attached, the temperature measuring instrument calculates the differential temperature and displays this as delta T. In addition, an acoustic alarm sounds when limit values are undershot or exceeded. You are free to define the limit values. 
 
The display illumination also enables easy reading of measuring values even in dark surroundings. In addition, the testo 735-1 temperature measuring instrument is waterproof according to protection class IP 65, has been tested in accordance with EN 13485, is HACCP-compliant and has international HACCP certification. 
 
Documentation of measurement data on site via the testo fast printer If you need evidence of the measured temperature values, we offer our optional testo fast printer as an accessory for the temperature measuring instrument. You can use this to print out the current temperature values or the min./max. values on site. 
Use the practical cyclical printing function on the testo 735-1 as well. It not only enables the printout of individual readings, but also of whole series of measurements on the testo fast printer at freely adjustable intervals (for example once a minute). 

We recommend you use the testo 735-2 version for saving, documenting and archiving measurement data. This temperature measuring instrument also has a reading memory and PC software.

  6. Distance to measurement spot 30:1
  7. Measurement spot marking 2-point laser
  8. Contact external thermocouple (TC type K) for contact type Measurement


With the testo 830-T4 laser temperature gun you will be well equipped for non-contact surface temperature measurements in industry and trade. It is especially distinguished by its 30:1 optics, which also enables the laser temperature gun to record extremely small measuring spots at a great distance. This therefore allows moving or dangerous objects to be measured from a safe distance. 
 
 All key advantages of the laser temperature gun at a glance. The laser temperature gun with laser measurement spot marker not only measures the surface temperature accurately, but also quickly (2 measurements a second). Benefit from these and other advantages of the non contact infrared thermometer:
     - High resolution processor provides accurate results (resolution 0.1 °C) 
     - 30:1 optics enable great accuracy at great distances on small objects being measured (1 m distance = 36 mm measuring spot diameter) 
     - Laser temperature gun with 2 point laser measurement spot marker: the measuring point can be precisely defined (= surface between the two laser points) 
     - Two limit values that can be defined as required 
     - Visual and acoustic alarm if limit values are exceeded 
     - Min./max. temperature display and hold function (to “freeze” a certain measured value) 
    -  An external temperature probe can be connected, e.g. to determine the emission level of the surface, or for additional contact temperature measurement 
     - Convenient operation (even with just one hand) thanks to the gun-style design 
     - Clear, legible display with background lighting 
 
Furthermore, the laser temperature gun delivers extremely fast results with a speed of two measurements per second. This means that extensive surface temperature scans are also easy to handle. 
 
Extended functions with the connectible probe, An optional external temperature probe to carry out contact measurements can also be connected to the testo 830-T4 laser temperature gun in addition to the non-contact IR measurement (e.g. for control purposes). There are a range of thermocouple probes available for temperature measurements of air, liquids, semi-solid media, and surface temperatures. 
 
The comparative contact measurement with a surface temperature probe will help you determine the emission level of the surface material which helps you set the laser temperature gun emission level accordingly in order to achieve the best results in the subsequent IR measurement. 
 
In case of surfaces with an extremely low emission level, we recommend using either an emission tape (optional), or the connectible contact probe (optional) throughout the measurement.
