testo 735-1, 3-channel instrument (thermocouples types K, T, J, S, Pt 100)

Durable, reliable, and compact measuring instrument with a connector for high-precision Pt100 probes and two connectors for fast-response thermocouple probes. Measurements from up to 3 additional temperature probes can be displayed on the screen. Using high-precision immersion/penetration Pt100 probes allows achieving a measurement accuracy of 0.05 °C with a resolution of 0.001 °C. This makes the measuring system ideal for use as a reference standard. Measurement results obtained with the testo 735‑1 can be transmitted via the IR port and printed on a Testo printer. Cyclic printing of data is also possible, for example, once per minute.

  • Measurement accuracy: 0.05 °C
  • Measurement data can be printed on a Testo printer on-site; cyclic printing is possible, e.g., once per minute
  • Device menu available in Russian
  • Display, save, and print differential temperature data, including min/max/average values
  • Acoustic alarm signal when limit values are exceeded
  • Protection class: IP65
  • Stable accuracy across the entire measurement range thanks to system calibration
