Digital pressure gauge 4_Refrigerant meter_Zhejiang Shuang'an Instrument Technology Co.,

Specification

Standard version

Robust, precise digital indicator
The robust stainless steel case and the battery power enable a flexible operation in various applications and industries. For a precise and quick on-site reading of a pressure value, a digital indicator is the ideal solution. The bar graph display and drag pointer function integrated into the display, as well as retrievable Min/Max peak values, enable effective analysis of the measuring point.

Customised installation
Through its rotatable case, the model DG-10-E can be easily adapted to local conditions. The backlighting also provides easy readability of the display in poor lighting conditions. Additional programming functions are: Automatic power-off, tare function and password protection. There is unit switching between the units bar, psi and MPa already integrated into the standard model DG-10-S.

Proven sensor technology
For decades, sensors manufactured by Double-An have guaranteed high accuray, long-term stability and repeatability in industrial pressure measurement.

Hardware functions

Rotatability of the display
The display of the model DG-10-E can be rotated through 300°, thus it can be read from almost any position. Therefore the model DG-10-E can also be used in situations where mounting is difficult.
Backlighting
The model DG-10-E features backlighting so that the display can be easily read, even under poor lighting conditions.
