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. |
