testo 735-1 - Temperature measuring instrument (3-channel)

0560 7351
  • 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)
  • 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, for example to calibrate stationary temperature probes, in the electronics and food industries or in laboratories.
    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.
    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 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).

    Caution: The instrument can only be commissioned with a probe. These are available separately.
