High-precision immersion/penetration probe (Pt100)

Order-Nr.  0614 0235

  • Pt100 sensor for highly accurate measurement results

  • Potential system accuracy of 0.05 °C at a resolution of 0.001 °C (depending on the measuring instrument connected)

  • Optional calibration to ISO or DAkkS possible

  • Measuring range: -80 to +300 °C

In conjunction with an appropriate temperature measuring instrument – e.g. the testo 735 – the high-precision immersion/penetration probe can achieve a system accuracy of 0.05 °C at a resolution of 0.001 °C.

Product Description

High-precision temperature measurements pose no problem for this immersion/penetration probe with Pt100 sensor. Combined with a suitable Testo temperature measuring instrument, such as the testo 735, its system accuracy is so high that the measurement system can also be used as a working standard. The probe is ideal for applications in quality assurance, for calibration services and in laboratories.
