Overview

If you want a very stable thermometer from –200 °C to 670 °C and are particular about the calibration, then look no further than Fluke's 5609 Secondary Reference PRT. Its short-term stability at the triple point of water is only ± 7 mK and its one-quarter inch (6.23mm) diameter lets you get accurate measurements in only 100 mm of immersion.

Features

- Temperature –200 °C to 670 °C (100 mm minimum immersion)
- NVLAP-accredited calibration, lab code 200348-0
- Dry-well reference with 90 ° bend

Major Applications

- Calibration of Temprature sensors
