• Accurate to ±0.10°C at 85°C

 • NIST certificate of traceability included

All Series 400 probes can be used interchangeably without meter recalibration. Probes are electrically isolated and come with a non-detachable 10 ft lead with phone plug (except as noted). Water-resistant junctions between probe and lead should not be immersed; detachable leads are not water resistant. The time constant is the time required to reach 63.2% of the temperature being measured. Five time constants are required to reach 99% of full reading. NIST traceability certificate is provided.
