Have questions? We're here to help!

To get the best possible performance from your MDM300 or MDM300 I.S., it is crucial to have appropriate sample conditioning for your measurement point. Options are available to cover all common sampling requirements – from verification of dry compressed air supplies, to the measurement of natural gas downstream of a glycol contactor.

• MDM300 mounted onto sampling system, connect the system to the sample collection point and measure.
• Gauge for monitoring sample pressure and flow control valves included
• Simple access for maintenance and replacement of filter elements
• Optional transportation case, to protect panel against damage in transit
