High-temperature infrared measurement

The Sentry ST675 is a non-contact infrared thermometer built for electricians and industrial technicians who need fast surface-temperature readings. Its rugged housing withstands job-site handling while the ergonomic grip allows one-handed operation during extended shifts.

Suited for high-heat diagnostics.

This tool serves maintenance crews checking electrical panels, motor bearings or HVAC components up to 1300 °C. Buyers who require certified calibration traces, data-logging memory or emissivity profiles for polished metals should evaluate dedicated process instruments instead.

50:1 distance-to-spot ratio

The 50:1 optical resolution lets operators measure small targets from a safer distance compared with 30:1 models. This single specification determines whether the ST675 can resolve the component size and working distance your application demands.

Questions about this item

What distance-to-spot ratio does the ST675 use for measurements?

The ST675 uses a 50:1 distance-to-spot ratio, meaning it measures a one-centimetre spot at fifty centimetres distance.

How do I install the battery so the thermometer powers on?

Open the battery compartment, insert a 9V cell matching the polarity marks, then close the cover until it clicks; the unit will not turn on if the polarity is reversed.

When should I send the ST675 for recalibration?

The manufacturer covers parts for three years and labour for one year; plan professional recalibration after the parts warranty expires or if readings drift beyond the stated 0.1 resolution.
