Probe Operating Temperatures

Standard Probes come with PUR (Polyurethane) jacketed cables. High Temperature Probes have FEP jackets.

Other temperature ranges may be possible. Contact us for more information.

Standard Probes: IP67

High Temperature Probes: IP63

U3 Probe

Standard Probe (PUR Cable):
-25°C to +125°C
(Available with optional FEP cable)

High Temperature Version Not Available

U5-18 Probes

Standard Probes:
-25°C to +125°C

High Temperature Probes:
-25°C to +200°C

U25-50 Probes
