Gas calibration - Import export

Over the last few years, we at EP-E have designed and introduced a series of primary standards for gases, designed for use in calibration laboratories. As a technology partner of the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, our solutions are based on the highest standards. The EP gas bell plungers generate a volume flow which is traceable to the SI units length and time. The pistons are driven by a stepper motor via a spindle. In the initial state one piston is fully retracted and the other fully extended. The volume flow can be set with high precision via the piston cross section and the travel speed. At the end of the calibration process, both pistons are in the opposite position to the initial position. The calibration device is preferably operated with air, which can be supplied with up to 6 bar. The EP gas bell pistons convince by highest measuring accuracy up to 0.15% (k=2).

The test bench is designed for calibration with critically operated nozzles of domestic gas meters or others such as diaphragm gas meters, ultrasonic meters, thermoelectric gas meters. The test bench is specially designed for the calibration of domestic gas meters (bellows gas meters, ultrasonic meters, thermoelectric gas meters). The test bench is modular - 1x6 to 4x6 clamping positions for the gas meters can be combined. Due to the modular design 1 to 12 gas meters can be tested simultaneously. In parallel, up to twelve additional test pieces can be adapted, run in and leak tested. A magazine consisting of three critical nozzles is used as flow transmitter. Optionally, a nozzle drum with nine combinable nozzles can be used. This allows the generation of up to 512 different flow points with highest accuracy.

The high-precision calibration laboratory is accredited according to DIN EN ISO/IEC 17025 for flow calibration of flowing gases. The EP calibration laboratory is accredited by the DAkkS according to DIN EN ISO/IEC 17025:2005 for calibrations of gases in-house and on-site under the procedure number D-K-21444-01-00. We offer calibrations for gas flow measurement as well as temperature, humidity and pressure measurements. In addition, we calibrate all measured variables of the test bench directly at your site. Our experienced technicians also check the harmonious interaction of all sensors, so that the entire system is perfectly tuned. The opening of our new calibration laboratory in Asia enables us to offer you even better service internationally.

10 litres calibration gas (100 ppm H 2 in nitrogen) for all FAN H 2 breath test devices. Compressed in an 1–litre aluminium can, at least 12 calibrations can be readily achieved.

Control valve and Flow indicator for use with calibration gas cylinder. Flow meter markings are nominally 0.5 & 1.0 litres/min.
