DM1 Digital Micro-Manometer Specifications
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.

|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.
Programmable 4 Mhz Microchip PIC14000 with 16 bit a/d.
DM1 functions can be updated by replacing this chip.
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.|
