Operating Temperature 4°C-50°C
Probe Operating Temperatures

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

Other temperature ranges may be possible.

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°CHigh Temperature Probes:
-25°C to +200°C
U25-50 Probes Standard Probes:
-25°C to +125°CHigh Temperature Probes:
-25°C to +175°C
*P-P resolution is 0.2%. In high EMI conditions (10 V/m), output level may shift and noise may rise to 600 mV RMS (6% resolution)

 

Probes and Ranges (Probe Dependent)

Listed specifications assume a 3 meter probe cable; flat measurement area diameter at least 3 times larger than the probe diameter; and no customizations.

Probes can be ordered as vacuum compatible; custom probesare available.
