DM1 Digital Micro-Manometer Specifications

Feature Specifications
Pressure Resolution: 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.
Internal resolution is 0.025 Pa (0.0001 "wc)
and this is the resolution of the serial output.
Pressure Range: Bi-directional: Range -3.0 "wc (750 Pa) to +2.2 "wc (548 Pa).
Membrane Keypad: 4 keys covered by weatherproof labeled overlay.
- Units Key: Select Metric (Pa) or U.S. ("wc) units.
- Zero Key: Reset display to zero pressure.
- Time Avg Key: Select block average of 1 (default), 2, 4, 8, 16 & 32 seconds.
- On/Off Key: Turn power on and off.
Accuracy: 1% of measurement or 1 display digit, whichever is greater.
Display Type: LCD with 1/2" high numbers.
Operating Temperature: 32°F to 122°F. (0°C to 50°C)
Storage Temperature: -4°F to 160°F. (-20°C to 70°C)
Low Battery Display: Current battery voltage is displayed at startup,
"lowbat" displayed when voltage is under 6 volts.
Maximum Pressure: 25 "wc, 6 kPa or 0.9 PSI
Over Range Indicator: "OP" is displayed when pressure out of -3.0 "wc (750 Pa) to +2.2 "wc (548 Pa) range.
Update Indicator: Decimal point blinks when display updates.
Weight With Battery: 8.9 oz. (253 grams)
Dimensions: 3.6" x 5.75" x 1.3/1.9" (91 x 146 x 33/49 mm).
Battery Life: Over 200 hours from one 9 volt alkaline.
Operating Medium: Air or non-corrosive, non-explosive gas.
Pressure Connections: Barbed for 1/8" ID tubing.
Analog Output Option: 0-5v out: ~0v is -3"wc/-750 Pa, ~2.5v is 0 "wc/0 Pa, ~5v is +3"wc/+750 Pa.
Voltage is independent of pressure display rezeroing. 2 wire plug and jack.
Analog Data Logger Option: The DM1 can be connected to an Onset data logger to simultaneously record temperature, humidity, light levels, and DM1 differential pressure. This logger has a pressure resolution of 0.4 Pascal or 0.0018 "wc over the range -3.0 "wc (750 Pa) to +2.2 "wc (548 Pa). Time resolution can be set from 1 second to hours, and logging duration ranges from hours to days depending on time resolution and number of sensors recorded. The DM1-U12-012 logger incorporates an Onset U12-012 four channel data logger, as described in the downloadable user manual (PDF) and the data can be plotted with the Onset HOBOware Pro software.

Serial Output Option: Female DB9 plug on 6 ft (2 m) cable. 9600b-8N0 pseudo RS232
protocol, ASCII records, ~1/sec, LF+CR termination, 32000 range,
0.025 Pa (0.0001"wc) resolution.
Microprocessor: Programmable 4 Mhz Microchip PIC14000 with 16 bit a/d.
DM1 functions can be updated by replacing this chip.
Custom Firmware: Custom microprocessor programming is available to optimize
the DM1 for your pressure measurement application.
Optional Accessories: Pitot tubes, static pressure probes & tubing.
Accessories Included: Battery, soft carrying case, tubing, calibration certificate, user manual.
Warranty: 2 years coverage on parts and labor to repair any defects.
