Negative Gauge Pressure is the difference in pressure between any vacuum and atmospheric pressure.
The maximum possible negative gauge pressure is always limited by the current ambient atmospheric pressure, which constantly varies, but is typically around 1 bar absolute.

Leak testing set for checking 1mb/min drop at negative 10 mbar vacuum - We need a suitable gauge to use as a leak testing test set we are looking to build. We need to measure down to -10 mbar and monitor for 1 minute to ensure the leak rate is not greater than 1 mbar/minute.
DM01 Multi-Range High Accuracy Pressure Gauge - High precision digital pressure gauge with 0.1% full scale accuracy, exchangeable pressure range modules from 100 mbar (1.5 psi) up to 400 bar (6000 psi).
