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.

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.
