## A high-accuracy portable temperature block

**Features**

![Beamex MB metrology temperature calibration block](https://www.beamex.com/app/uploads/2016/08/MBxxx-laboratory-v1-scaled-1.jpg)

#### 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.

#### Loading

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.
