This range of single piston deadweight testers are designed for calibration of pressure measuring devices used with gas applications. They are available in a number of different pressure units and each features a 1/4 NPT female external supply for connection of a gas supply source, such as a nitrogen bottle or compressed air.
The precision piston-gauge system allows for the masses to balance the upward force which creates pressure within the system. There are 3 standard masses included, each one is marked with the serial number of the unit and a nominal pressure value that is relative to the piston.
These deadweight testers can be specifically calibrated to local gravity, at no extra cost. This is because gravity varies and has a direct effect on the force of the weights, which in turn can affect the accuracy. If not specified, the standard gravity is set to 980.665 cm/s2.
The optional PressCal software, a windows based program that allows for the entry of necessary corrections to enhance the performance of the deadweight tester. The calibration details are stored and used to create a calibration certificate. Using the software, the accuracy improves to 0.008%.
Key features include:
Accuracy better than 0.015% of reading (improved to 0.008% with PressCal software)
Different pressure units available
Built-in pneumatic hand pump
High quality needle valve for optimum control
O-Ring design eliminates the need for wrenches or PTFE tape
