UCal 400+ Portable Dri-Block Calibrator
– 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
– Independent over-temperature protection
– Only 4kg with included multi-well insert
The UCal400+ provides a safe, dry and constant temperature source and can be used either on a bench top or as a portable field 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.
he temperature control circuit is built into the unit.
Even though the unit heats up rapidly, highly efficient 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.
Cooling Probe
This rapid cooling probe is designed to cool the block on a Tecal 425, 650 or 700X and Ucal 400+.
The water cooled probe will cool a unit down to 10°C if an insert block with a diameter 10mm or 3/8inch bore or larger is used.
