HI 955501

From - 199.9 to 850°C with 4-wire Pt100 Thermometers


Pt100 models are widely recognized as the most accurate with the best stability, repeatability and linearity among thermometers. Add to this the 4-wire system that is practically impervious to lead-wire length error and you have a powerful tool to measure temperature accurately. We have designed two affordable models for you to choose from: HI 955501 with the interchangeable HI 768 Pt100 probes and HI 955502 with the fixed general-purpose probe and 1m (3.3') lead, at a very attractive price.

Both models measure temperatures with 0.1°C resolution in the -199.9 to 199.9°C range and then automatically switch to 1°C from 200 to 850°C. Press RANGE and the resolution switches to 1°C at any time. A compact, ergonomic design and a wrist-strap make it easy to carry them anywhere in the lab or plant.

The shockproof boot is recommended to protect the meter during field measurements.
