Features and benefits
  • –200 °C to 300 °C temperature range
  • Nominal 100 Ω resistance

100 Ohm RTD temperature probe

The TP750 probe is manufactured using a coil suspension element design for increased shock and vibration resistance. The mineral-insulated sheath provides a minimum bend radius of 19 mm for flexibility and durability. The TP750 temperature probe is compatible with the DMM4050 digital multimeter.


All specifications are guaranteed unless noted otherwise.
