PTB 1200 – High Temperature Portable Thermocouple Calibration Furnace, 1200 ºC

  • Range : 100 to 1200° C
  • Longer immersion Depth: 190 mm
  • Large diameter insert :34 mm


The PTB 1200 is an high temperature calibrator designed for both laboratory and on-site use. It is ideal to calibrate temperature sensors in a wide range from 100 to 1200 °C.  It feature a long effective immersion depth of 190 mm which make it suitable for calibrating even larger temperature sensors.

The standard metal insert have 4  pockets (holes) of  125 mm depth- A Ceramic insulator with length of 65 mm is supplied as standard. This makes an overall immersion depth of 190 mm which is considerably  deeper than any comparable temperature calibrator in the market. Deeper immersion depth allow for large diameter temperature sensors to be calibrated
