Suitable for all sterile processing environments.

A heavy-duty, heat-resistant gasket seals out moisture, preventing icing and condensation, even in wash-down areas.

An adjustable pointer provides easy, precise recalibration. This feature also permits setting for zero calibration error at any desired temperature point within scale range.

Deep-drawn 3 inch or 5 inch metal dials with aligned pointer provides an anti-parallax design, creating significantly improved legibility and reduced reading errors. Low glare dial background surface printed with high-contrast numerals and graduations.

Consistent accuracy is achieved within one scale division. High accuracy range of 120° to 200°F in 0.5°F divisions. Ambient temperature changes in the thermometer’s case location will not affect accuracy.
