Fluke 6531-200M-B Offers

Its electronic reference pressure monitor is a special version of RPM4, designated RPM4-E-DWT. RPM4-E-DWT can be configured with one or two high precision quartz reference pressure transducers (Q-RPTs) with ranges from 7 mPa (1 000 psi) to 200 mPa (30 000 psi).


No weights to load and unload, transport or send out for calibration
Provides real-time pressure indication with no need to know and correct for local gravity or ambient temperature
No piston-cylinder changes
No significant sensitivity to level or vibration
Able to set and read any pressure value exactly, no minimum increment limited by smallest available masses; perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
Operates in any unit of measure, switching easily from one unit to the next
