According to Hanna Instruments , Pt100 models are widely recognized as the most accurate with the best stability, repeatability and linearity among thermometers.

Add to this the four-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 1 m (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 rubber boot is recommended to protect the meter during field measurements.

HI 955501 is supplied complete with battery and instructions. HI 955502 is supplied complete with fixed temperature probe (general purpose), battery and instructions.
