We need a system to monitor overpressure, temperature and humidity for a new cleanroom that we will be extending.
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.
We carry out resource tests on water wells. For the tests we need to record the speed at which the water drops within a borehole at a certain flow rate.
