Over the years, ERTCO has designed thermometers for customers with needs that were not filled by instruments in their normal product line. The following listings are among those that were developed, have gained popularity, and are now used in many special applications. They include a variety of ranges, subdivisions, immersions, and lengths. All are accurate to within NIST tolerances.

Any of these thermometers may be furnished with ICL's NIST Traceable Report of Calibration upon request.
