All Pro Bi-Metal Thermometers
Brand: Palmer Wahl Instruments, IncPalmer’s All Pro Thermometers are an economical alternative to our All Star line.
All Pro’s feature all welded 304 stainless steel construction which provides the resistance needed in corrosive working environments, vibration, and other rugged conditions.
The instrument has been designed to handle accurate temperature measurement for most industrial and laboratory applications, giving these thermometers a long service life.
The low cost and high quality of the All Pro Thermometers make it a popular instrument for many applications.
FeaturesEasy-to-Read Dials in 3" or 5" Diameter
- Dials are specially fabricated of low-glare finished metal using a deep drawn design for anti-parallax alignment of the pointer to graduation marks. High-visibility dual scale numerals and graduations help minimize reading errors.
Temperature Ranges
- All Pros are available in °F scales, and Dual °F & °C scales with exceptional legibility. Ranges cover temperatures from -40°F (-40°C) up to 500°F (260°C).
Simple, Convenient Recalibration
- With a hex nut located on the back of the case allows for easy recalibration.
Environmentally Conscious
- Bimetal sensor eliminates any concern over mercury or glass tubes.
Fast Response
- Superior heat transfer characteristics, fast response, and consistent repeatability are achieved through the use of a high-torque, low mass bimetal sensing element.
- Materials and design combine to convert the sensor’s movement quickly and accurately into a dial reading.
- Ambient temperature changes at the case will not affect accuracy.
