Overview

Designed for controlled bluing, plating, and parkerizing work, this thermometer helps monitor bath temperature where consistency matters. It is carefully sealed for use in a caustic bluing bath and is calibrated and double-checked for accuracy before sale. The long stem allows only part of the thermometer to be immersed, helping keep the dial out of the salts while the included stainless steel clip supports secure placement. This is a practical shop tool for gunsmiths and finish work, with a straightforward design focused on temperature control rather than extra features.

Pros

  • Designed for accurate temperature readings in bluing, plating, and parkerizing baths.
  • Carefully sealed for use in caustic bluing bath conditions.
  • Each thermometer is calibrated and double-checked for accuracy.
  • Long 6-inch stem allows only 3 inches to be immersed.
  • Includes a stainless steel clip for bath placement.
  • Wide 50°-400°F range covers common finishing bath temperatures.

Considerations & Trade-offs

  • Designed for bluing, plating, and parkerizing baths, so it is specialized rather than a general-purpose shop thermometer.
  • The 50°-400°F range may be broader than needed for some tasks, but it also means the dial is not optimized for a narrow temperature window.
  • Only 3 inches of the 6-inch stem need to be immersed, which helps keep the dial out of the salts, but it still requires enough bath depth for proper placement.
  • The clip is included, but the product data does not specify compatibility with every tank or container style, so fit should be checked for your setup.
