THE UCAL 400+
Introduction
Techne’s UCAL400+ calibrator heater provides a safe, dry, constant temperature source. It is fast and economical
and can be used either on a bench top or as a portable field unit. The weight of the unit is only nine pounds/four
kilograms. 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.
Features include:
• 10 insert formats available
• Maximum temperature of 430°C/806°F
• An independent over-temperature cutout
• Temperature sensor burnout protection
Even though the unit heats up rapidly, highly efficient insulation ensures that the case remains cool enough to
handle even at maximum operating temperatures. Techne’s calibrator has been designed to comply with all
relevant Radio Frequency interference and electrical safety regulations.
