MRU Instruments DM 9200 Specifications
Suitable for continuous measurement of pressure, low pressure and differential pressure for non-aggressive
gases, e.g. gas flow pressure, nozzle pressure, combustion chamber pressure and chimney draft.
FEATURES
˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃˃ADVANTAGES
˃˃
Easy handling due to a compact and lightweight case and a large display
˃˃
All functions of the logical software are operated with only 3 keys
˃˃
Additional data integrity of measurements through print and memory function
˃˃
The programmable average value calculation allows a “smoothing” of highly fluctuating
measuring values in low pressure ranges
˃˃
Very sensitive low pressure ranges are not a problem with the long-term stability
