Ametek Jofra STS100B350DH Probe, Pt100 Reference, 350 mm

Ametek Jofra STS100B350DH Probe

Overview

The STS100B350DH is a JOFRA STS-100 series superior reference sensor, decoded as type B (6.35 mm diameter), 350 mm straight stem, D cable option (2 m with REDEL connector for the DTI050 readout) and H certificate (ISO17025 accredited, -45 to 650 °C). The Pt100 element covers -150 to 650 °C overall and works as a temperature standard alongside JOFRA calibrators and dry-wells.

STS-100 sensors are built for extremely stable performance: repeatability is 0.002 °C, hysteresis at 0 °C is 0.01 °C, and long-term stability is typically 0.014 °C after 100 hours at 650 °C. The sensing element sits in an Inconel 600 outer tube with a 4-wire LEMO-family connection, and each probe passes annealing, mechanical stress reduction and final calibration before certification.
