Small diameter ITS-90 platinum Resistance Thermometer
Netsushin and AIST succeed in developing the small size of PRT elements that have temperature resistance characteristics meet ITS-90 requirement for resistance ratios. Developing these small elements allow us to install them easily into the small diameter of stainless steel pipes(probes). We are now able to provide two models of ITS-90 PRTs with very small diameter.
These ITS-90 elements are also available for customized sensor, installation into small blocks or other applications are the options.
