Beamex MB

Metrology Temperature Block

A high-accuracy portable temperature block

Beamex MB metrology temperature calibration block

High accuracy and stability

With a conventional dry block, you typically needed an external reference
sensor if you wanted better accuracy. The Beamex MB has accurate internal
temperature measurement and display accuracy up to ±0.1°C, so you can get
high accuracy even without an external reference sensor. With its unique temperature control technology, the Beamex MB has excellent stability up to ±0.005°C

Built-in high-accuracy reference input

In order to receive the best accuracy from the MB, there is a possibility to
connect an external reference sensor into the reference sensor connection (R
model). This eliminates the need for a separate reference thermometer. The
reference sensor measurement is accurate up to ±0.006 °C. ITS-90 or CVD
coefficients can be used to compensate any sensor errors.

Axial uniformity

With the unique dual zone control and extended well depth, the Beamex MB has
an excellent axial uniformity up to ±0.02 °C.

Immersion Depth

The Beamex MB series provides immersion depth up to 203 mm (160 mm in
MB140), which, together with the control technology, provides more stable
calibration. Moreover, a deeper immersion depth reduces the stem conduction
error (heat loss into the atmosphere), especially at higher temperatures.


With the extended well depth and the dual zone temperature control feature, the
Beamex MB can correct the effect of loading and provides loading
specifications up to ±0.005 °C.

Communication with Beamex MC calibrators

The communication port enables communication with selected Beamex MC calibrators for automatic calibration and documentation. Combined with a Beamex MC6 calibrator, loop calibrations are possible with conventional, HART and Fieldbus temperature transmitters with sensors.
