We have a need for a general vacuum digital gauge which can display 0-1000mbar vacuum as absolute readings. The accuracy required will be 1mbar, and the device should be battery operated, and the battery type should be commercial available for easy maintenance.
We would suggest the DM01 which has a 1 bar absolute range and will be accurate to 0.05% FS (0.5 mbar). The DM01 use 3 x AA 1.5V batteries which are very common battery and easily obtained from any place that sells batteries.
- Pressure Sensor Modules: 1 bar (14.5 psi) absolute
- Process Connection: 1/4 NPT male
