Platinum Resistance Thermometer (PRT)

The Platinum Resistance Thermometer (PRT) is a high-precision temperature measuring instrument developed for accurate temperature determination in laboratory, research, and industrial environments. Manufactured by Micro Technologies, this thermometer utilizes the predictable change in electrical resistance of platinum with temperature to provide highly reliable and repeatable measurements.

The sensing element consists of a fine platinum wire with an approximate resistance of 2.8 Ohms, carefully wound on an insulating mica frame to ensure excellent thermal stability and measurement accuracy. The platinum wire is inductively wound and permanently soft soldered to sturdy copper leads, minimizing resistance errors and ensuring dependable electrical connections.

The thermometer incorporates four connecting leads, including a pair of compensating leads, which help reduce lead resistance effects during precision measurements. These leads are terminated through high-quality brass terminals, allowing secure and convenient connection to resistance bridges, Wheatstone bridges, digital resistance meters, and laboratory measuring instruments.

The platinum sensing assembly is mounted on a durable mica frame and enclosed inside a stainless steel protective tube, providing mechanical strength while ensuring rapid heat transfer and long-term reliability. The robust construction makes the instrument suitable for repeated laboratory use and accurate temperature calibration work.

For safe transportation and storage, the Platinum Resistance Thermometer is supplied in a velvet-lined protective case, safeguarding the sensing element from mechanical damage when not in use.

The Platinum Resistance Thermometer is extensively used in engineering colleges, universities, physics laboratories, thermal engineering laboratories, calibration laboratories, research institutions, industrial quality control laboratories, educational institutes, and scientific research centers.

Every Platinum Resistance Thermometer manufactured by Micro Technologies undergoes rigorous quality inspection and calibration to ensure dependable performance, excellent stability, and long operational life.
