Sanitary Bi-Metal Thermometers

Brand: Palmer Wahl Instruments, Inc
Palmer’s Sanitary Bimetal Thermometers are specifically designed for all sterile processing environments.

Choice of 12 temperature ranges in Fahrenheit or Celsius ensures just the right thermometer for your sanitary processing or storage applications.

Our experience in the field enables us to offer a line of sanitary thermometers with the design, quality and craftsmanship that make them an industry standard for rugged reliability and consistent accuracy.
Features
Installed Directly into Process

  • No thermowell needed. Palmer Sanitary Bimetal Thermometers utilize standard Tri-Clamp® sanitary fittings for faster installation and speed of response with reduced installation costs.
Complies with 3A Sanitary Standard

  • All product contact surfaces and radius’s comply with this industry wide standard.
Accurate

  • Consistent accuracy is achieved within one scale division. Ambient temperature changes in the thermometer’s case location will not affect accuracy.
Environmentally Conscious

  • Bimetal sensor eliminates any concern over mercury or glass tubes.
Simple, Convenient Recalibration

  • An adjustable pointer provides easy, precise recalibration. This feature also permits setting for zero calibration error at any desired temperature point within scale range.
Easy-to-Read Dials in 3" or 5" Diameter

  • Deep-drawn metal dial 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.
Hermetically Sealed Case and Plexiglass Lens

  • Internal elements are secured in the stainless steel case by means of a quick-lock, cam-action bezel ring.
  • A heavy-duty, heat-resistant gasket seals out moisture, preventing icing and condensation, even in wash-down areas.
