100 Ohm RTD Temperature Probe

TP750

Features & 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.
