We are looking to measure have to measure vacuum from zero to -150mbar to a resolution of 0.1 milibar. Which pressure gauge could we use to measure this vacuum?
The Baroli is a precision digital pressure gauge would have a 0.08 mbar resolution worst case for a range of 0 to -160 mbar gauge. Although the apparent resolution would be 0.01 mbar for the displayed reading of 150.00, the ASIC inside the instrument has a resolution between 11 and 12 bits or 2048 to 4096 steps which is what limits the resolution to 0.08mbar, but this is still within your requirements. Also please note that the accuracy will be +/-0.4 mbar which is additional to the reading resolution.
- Pressure Range: 0 to -160 mbar g
- Accuracy: 0.25% FS BSL
- Media Compatibility: Stainless steel 316L and FKM seals
- Pressure Connection: G1/4 male EN837
