High-Accuracy Electronic Balance

The High-Accuracy Electronic Balance LEEB measures sample mass in the core laboratory. Mass is the input to grain density, porosity and saturation calculations, and the balance weighs plugs, full-size core, cuttings and fluids. Three typical configurations are offered, one for plug-size samples and two for full-size core. The choice depends on the heaviest item to be weighed and the resolution the test method needs.

How it works

It is a digital balance that reads sample mass directly. For plug-size samples the typical unit weighs from 0 to 600 g with an accuracy of 0.001 g. That resolution suits gravimetric methods such as Dean-Stark saturation and helium porosimetry, where small mass differences carry the result. For full-size core the typical units weigh up to 2,500 g or 6,000 g with an accuracy of 0.01 g.

All three configurations run on 110 to 220 VAC at 50 or 60 Hz.
