Accurate, Temperature Readings For Bluing, Plating & Parkerizing Baths
Accurate temperature control of the bluing bath is absolutely a
must for long lasting, true-color blue jobs. Brownells stainless
steel Bluing Thermometer is carefully sealed for use in the caustic
bluing bath. Each and every thermometer is calibrated and
double-checked for accuracy. Cheap, poorly constructed
thermometers cause more bluing failures than any other single
thing, and it is our feeling that any company offering them for sale
to gunsmiths has little knowledge of the bluing game. Brownells
Bluing Thermometer has a long, 6" stem. Only 3" of the stem need
to be immersed in the bath, leaving 3" of safety margin to keep
the dial out of the salts. Supplied with a Clip to attach the
Thermometer to the tank and keep it 1" from the side and 1"
above the bottom of a 6" deep tank.
