Automatics dead weight testers BA4

If you are looking for traceability and accuracy, this range of prymary standards is the best !

These primary standards are intended for testing, adjusting and calibrating pressure measuring instruments. Very high precision, they are suitable for calibration laboratories or industries with intensive or regular calibrations.

calibration : Our dead weight tester are calibrated under the following conditions of use : Temperature 20°C - Pressure atmos. 1013.25 hPa - Humidity 50% - acceleration 9.80665 m/s²
fluid : Dry air - gas connection ¼ cylindrical female - This balance needs to be connected to a pressure source.
tank : 20 cm3 for models with lubrification
seat adjustment : Leveling bubble and adjustable feet
connection for the instrument to be test : adaptor G1/2 standard – other optional adaptors
motorization of weights : motorization of the set of weight by electric system
crankcase : Light alloy aluminium AG3 + high-resistance paint
capstan : removable for transport
piston/cylinder : single
weights : Ergonomic shape of the masses, easy loading of the masses on the bell - Marking corresponding with the measuring unit choose (bar, mbar, KPa, PSI etc..) – Gravity : standard (9.80665 m/s² or local gravity at your choice without supplement
operating temperature : 18 to 28°C - 64 to 82°F
