Datasheet

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 the unique temperature control techniques the Beamex® MB has excellent stability up to ±0.005°C. This kind of stability has usually been found only in baths, not in dry blocks.

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.

Radial uniformity

Radial uniformity is the temperature difference between the holes in the insert. It is naturally crucial that the reference sensor and the sensor being tested are at the same temperature. The Beamex MB offers radial uniformity up to ±0.01 °C.

Immersion depth

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