Ametek Jofra STS200B915EH Reference Probe, Pt100, 90° Angled, -65 to 160 °C

Ametek Jofra STS200B915EH Reference Probe

Overview

AMETEK's STS reference probes are the working standards used to verify true temperature in handheld, dry-block and liquid bath calibrators, and the STS-200 series spans -100 to 700 °C across its variants. Type 915 versions are the 90° angled probes matched to the RTC-156 and RTC-157 calibrators, so sensors under test still fit alongside them in the well.

This B-size 915 probe has a 6.35 mm (1/4 in) INCONEL 600 sheath, a 179 mm stem and 110 mm minimum immersion depth. Resistance is converted to temperature on the ITS-90 scale with probe-specific coefficients, and the H option adds an ISO 17025 accredited certificate calibrated over the standard -45 to 155 °C span.
