PTC Metrology™ offers NIST Traceable calibration and certification services.

Take a look at our Portable Steel Hardness Tester

The Portable Steel Hardness Tester measures the hardness of metals in the range of 20 to 65 HRC on the equivalent Rockwell C Scale. The instrument is fully portable and easy to use. It can easily be carried anywhere an accurate hardness test is required

PTC® Model 307L is the standard for testing Pipeline Coatings.

PTC® IVF Thermometers are designed for hospitals, IVF, and embryology Labs.

PTC® Industrial Rail Thermometers are designed to measure surface temperatures for continuously welded or jointed rails. These thermometers meet the criteria for the AREMA specification on track maintenance.

Direct Contact Spot Check® Thermometers

PTC®'s Spot-Check® Series of thermometers feature outstanding response and sensitivity. Their extremely low thermal mass and weight (1/2 ounce), along with a unique design, assure intimate thermal contact and a very rapid readout. Each thermometer is guaranteed to an accuracy of ± 2% of full-scale range. The instrument's bimetallic coil directly contacts the surface to be measured. In response to temperature, the sensor expands or contracts to cause the dial itself to rotate.

These instruments can be used to quickly check surface temperatures or can be permanently mounted. They can be used for such applications as hot plates, griddles, furnaces, annealing and curing ovens, weld preheats, motors, generators, engines, bearings, etc. Available in either Fahrenheit or Celsius models, they come in several temperature ranges, covering a total span of 0° to 1000°F (0°C to 525°C).

Two models are available with stainless steel dials that are designed for use in vacuum chambers. Models 575FMSS and 575CMSS feature dials with no paint or ceramics that could outgas. The dials are made with uncoated metals and etched to provide the temperature markings.

All Spot Check® thermometers come with a spring lifter knob to enable the user to safely remove the instrument from a heated surface. The knob is threaded and attaches to the center post of the thermometer.
