If you want a very stable thermometer from –200 °C to 670 °C and are particular about the calibration, then look no further than our 5609 Secondary Reference PRT

For years, you’ve relied on our 5612, 5613, and 5614 Secondary Reference Probes. These field-durable, lab-accurate PRTs have been replaced by the 5615, which comes with a NVLAP accredited calibration

When buying a PRT, performance isn’t the only criterion you need to look at. The real issues are price-to-accuracy and price-to-durability ratios
