UCal 400+ Portable Dri-Block Calibrator
Calibrate your temperature sensors and systems with our economically priced portable unit!
Key Features
- Wide temperature range
- Built in program for thermal switch testing
- Maximum temperature of 430
°C/806°F
- Fast heat up and cool down
- 10 insert formats available

The UCAL400+ Calibrator provides a safe, dry and constant temperature source, and can be used
either on a bench top or as a portable  eld unit. The unit covers the temperature range from 5°C
above ambient up to 430°C using a machined aluminum insert block as the heat transfer
medium. The temperature control circuit is built into the unit. Even though the unit heats up
rapidly, highly e cient insulation ensures that the case remains cool enough to handle even at
maximum operating temperatures. This calibrator has been designed to comply with all relevant
Radio Frequency interference and electrical safety regulations.
