Martindale PM85 Differential Manometer
Measure differential pressure with high levels of accuracy using this Martindale pressure meter!
Capable of measuring pressure in eight different units (mmH20, mmHg, psi, inH20, inHg, hPa, mbar and Pa) the PM85 can measure pressure up to 1.45psi (100mbar) or the equivalent range for other units (see tech specs table for full list of ranges). It is also possible to use the PM85 to measure air speed, but this requires an optional pitot tube (sold separately - please call for inquiries).
As well as standard measurements, the PM85 can calculate MAX, MIN (or both values together) and average measurements so you can get an idea of what measurements are happening over a time period.
