| Features |
The PRXA is a microprocessor-based differential pressure recorder designed for use in hospital isolation rooms, HVAC balancing, pressure monitoring and clean room monitoring. Its large digital display and 8" diameter chart deliver easy to read results.
- Alerts personnel when differential pressures are too low or too high through audio and visual alarms.
- Adjustable plastic tubing provides remote sensing options and the ability to position recorder inside or outside critical environments
- Provides exceptional data accuracy and response time
- Monitors and records continuously for up to 31 days
- Provides real time differential pressure information
- Records on 8" circular chart for convenience and exceptional data resolution
- Displays minimum and maximum readings for spot checks
- Tamper resistant locking keypad and door
- Allows user to program recording time and data range
- Large digital display allows quick visual checks at all times
- Microprocessor control & sensors provide high accuracy and repeatability
- 30 Day Money Back Guarantee

| Specifications |
Accuracy: ±.004, ±3% of reading
Ambient Operating Conditions (recorder): 0 to 90% RH (non-condensing), +32 to +120°F (0 to +50°C)
Output Ranges: User selectable; -.10 to +.10 IN WC (inches of water column), -.15 to +.25 IN WC, 0 to +.15 IN WC, 0 to +.25 IN WC
Power Supply: 120V AC adapter (240V adapter available) use four "D" batteries for back-up power
Dimensions: 10.5" x 13.2" x 2.8" (26.6cm x 33.5cm x 7.1cm)
Alarms: Audio (90 decibels)/Visual high and low alarms; programmable alarm delay (warning mechanism, no controller functions)
Average Battery Life: 2 days or more under normal conditions (Batteries for back-up power only) Note: Response time is slower when using battery power source
Average Response Time: 20 seconds for 60% step change Note: The PRxA internally averages readings together. In battery mode the update rate is slowed to conserve power and since the unit takes 1 one reading per update, the response is also slowed.
Calibration Adjustment: User zero adjustment

Display Resolution: 0.001 all ranges
Mounting: Free standing or wall mountable (keyholes)
Recording Time: User selectable: 1, 7 and 31 day
Sensor: Differential pressure transducer
Warranty: 1 year
Weight: 3.5 lbs. without batteries (1.5 kg), 5 lbs. with batteries (2.2 kg)
Includes: Pen, Box of 60 (-.10 to +.10/7 day) Charts, 6' of tubing, AC adapter, 1-point NIST Traceable Certificate of Calibration, and Instructions.
Optional NIST traceable certificate of calibration available |
