Palmer 300 Series Classic Industrial Thermometers set industry standards for accuracy, quality, and rugged operation. With looks to match their performance, these classic thermometers are designed and constructed for long-term industrial process service. For some applications requiring maximum response time using a union instead of a thermowell, specify one piece stem and bulb.
Available in straight, 90° back angle, 90° left side, 90° right side, 45° incline, or 45° recline angles.
The 9 inch (220 mm) case is made of extruded V shaped brass with a chrome finish. Numerals and graduations are printed on a painted metal scale; engraved scales are optional for some ranges. The "Red-Reading" lens glass tube is individually calibrated, thoroughly annealed and aged for permanent accuracy.
Mercury Fill is standard; red spirit fill is optional for temperature ranges up to 300°F / 150°C. Mercury filled models have an accuracy of ±1/2 scale division, and red spirit filled models have an accuracy of ±1 scale division. *Please note that only mercury fill is suitable for food processing applications.
