Model DM1 Digital Micro-Manometer

The Infiltec Model DM1 micro-manometer is a portable digital micro-manometer with the easy-to-use 0.001 inch water column or 0.1 Pascal digital resolution units that can solve your toughest differential pressure measurement problems. Applications include HVAC test and balance, radon mitigation, furnace draft analysis, duct leakage testing, pressure balancing, combustion safety analysis, advanced building diagnostics, laboratory safety monitoring, clean room monitoring, isolation room monitoring, process monitoring, filter condition checks, environmental assessments, and Pitot or orifice pressure measurements. Comes in padded carrying case with 9v battery, extension tubing, manual, and calibration certificate.

• The DM1 is the differential pressure measurement standard for radon mitigation professionals, and for laboratory, field, school, office, or home use. It comes with a padded case, 9v battery, two 4 ft (1m) extension hoses, a user manual, and a calibration certificate.
• Display resolution of 0.1 Pascals or 0.001 inches water column. Display Type: 3.5 digit LCD display with 1/2" high numbers. Displays to 0.1 Pa below 200 Pa, and to 1 Pa above. Displays to 0.001 "wc below 2"wc, and to 0.01"wc above.
• 4 key membrane Keypad: Units key selects Metric (Pascal) or U.S. ("wc) units, Pressure zero key resets display to zero pressure, time average key selects block average of 1 second (default), 2, 4, 8, 16 & 32 seconds, and On/Off power key.
