The 903 Dry Block is available in two models, the Site model, which has both a
controller and a built in indicator for use with type ’N’
thermocouples, and the Basic model, which has only the controller. The
unit features a shutter device on the front panel to protect the user
from heated inserts falling out whilst the unit is being moved or
carried, and an internal fan to aid in the cooling of the block.
An optional cooling
accessory is available which connections for an air supply and speeds up
the cooling of the unit. The calibration volume is 25mm diameter by

inserts can be provided with specially drilled calibration pockets to
suit your special requirements.
