Volume Comparator

Sartorius volume comparator for determining the volumes of solids, especially of weights.
Special performance features:
- Monolithic weighing technology
- Calibration of the volumes of objects with masses of 1 g to 1 kg according to the buoyancy method
- Highly accurate differential weighing in liquid
- Load receptor for individual weights of any shape and of density standards and density reference spheres
- Fully automatic measurement sequence for any combinations up to 1 kg
- Closed weighing chamber in liquid equipped with feedthroughs for the load alternator, sensors, weighing pan and loading device
- The water batch completely surrounds the weighing chamber in liquid
- Automatic load alternator with 9 positions in liquid (FC40)
- Second automatic load alternator with 9 positions for measuring the mass of substitution weights in air
- 2 temperature sensors (PT100) in the weighing chamber with measuring bridge, readability of 0.001°C
- Additional sensors for air temperature, relative humidity and air pressure are integrated in the weighing chamber for air
- Measurement equipment and controls in two separate cabinets with access to all components
- Industrial standard PC with TFT monitor
- Software for control and calculation of density values
- Control panel with ports for additional networking (USB, LAN)
- Thermally insulated and closed measurement cabinet contains water bath in liquid and built-in load alternator sensors in air and liquid, motor for lifting and rotating mechanism, and a granite slab for the mass comparator with feedthrough for below-balance weighing

* Repeatability is the standard deviation "s"; it is calculated from 6 ABBA cycles, after eliminating drift.
Prerequisites for the standard deviation are good climatic conditions in accordance with the OIML R111 Guideline.
Setup and installation by our special mass comparator technicians from Germany is required.
