Description
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.
Customised installation
Through its rotatable case, the model 324 can be easily adapted to local conditions. The back lighting 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 kgf/cm2 bar, psi and
MPa KPa ,mmH20 , Pa , mH20 already integrated into the standard model 324 。
Proven sensor technology
For decades, sensors manufactured by Autumntree have guaranteed high accuracy, long-term stability and
repeatability in industrial pressure measurement. Depending on the measuring
range, the most appropriate sensor technology is used (metal thin-film or ceramic).
