The built-in high-pressure gas storage system should be filled via the appropriate connection. Three differential pressure gauges are built in to display the internal pressure system, control pressure and output pressure. The maximum test pressure is set by the pressure regulator. The output pressure at the two test connections is precisely controlled by two precision needle valves and the balanced volume regulator. The connected reference pressure gauge indicates the preciise pressure at the test port. Externally generated pressure can also be measured via the test connection. The teostel is supplied with quick-connect test and fill hose, a 1⁄4″ NPT male adaptor for the test connection and connection for refilling.
MNR-300 Pressure case up to 200 bar
Autonomous high-pressure power supply and control system
The MNR pressure case is the ideal tool for carrying out your high-pressure calibrations in the field.
The pressure case is equipped with a gas cylinder and a precision control system that allows you to precisely regulate the output pressure between 0 and 200 bar
As a pressure reference, you can use various instruments that fit perfectly in the case and make this system as a universal pressure calibrator
You can obtain the printing case for following devices:
- Addditel 681 precision pressure gauge
- Additel 672 pressure calibrator
- Beamex MC5 calibrator
- Fluke 725 with pressure modules
- Fluke 700 series precision pressure gauges
- GE DRUCK DPI620 series calibrators
