PTFE Temperature Probes – Electroplating

The Electroplating industry uses corrosive chemicals and acids that produce a harsh environment that can corrode and downgrade the performance of temperature probes. Chromic acid and Sulfuric acid, commonly used in chrome plating, require plating bath temperatures to be maintained in the 160°-170° F.

Other chemicals used in the plating and etching industry including Hydrofluoric acid, Hydrocyanic acid, Nitric acid, also require corrosion-resistant Temperature Probes impervious to corrosive chemicals and acids, for process control.

MASTCO Temperature Probes are completely “sealed” and encapsulated in PTFE , not ‘heat-shrink wrapped’ or ‘coated’, therefore they don’t “leak”. They also are sturdier due to thicker molded walls, while retaining “high” response times, due to our unique designs. The wall thickness range is 0.015 – 0.030 mils for best chemical resistance and excellent response times. They are designed for long working life and are resistant to harsh chemicals, as well as some amount of roughness in handling, and normal wear and tear, such as insertion and removal in the plating baths.

MASTCO Temperature Probes can be 2-, 3-, or 4-wire RTD’s (100d or 1000d), thermocouples, or customer specified thermistors encapsulated with PTFE. Probes can be supplied with braided or unbraided cables with superior PFA sheathing, which can withstand immersion temperatures to 482°F and provide corrosion resistance. (PVC cable working temperature is in the range -22°F to 221°F, compared to PFA cable working temperature, which is in the range -328°F to 482°F.) The probe can be designed to plug into a current system, such as a Flaretek® fitting, or the customer’s design specification.

Our regular customers include Original Equipment Manufacturers (OEM) and users of electroplating baths and tanks, process heaters, semiconductor cleaning/etching equipment, and many standard and unique applications in chemical, biological, medical, pharmaceutical areas including stem-cell research and long term storage.
