Product Details
✓Dual-Port Pressure Testing for HVAC – This digital manometer measures pressure at one point relative to ambient air or compares pressure between two connected points. Use the HVAC manometer for duct static pressure, filter differential pressure, blower checks, ventilation troubleshooting, and suitable boiler or clean-room applications. For a single-port reading, leave the unused port open to still air. For a two-port reading, connect both hoses and press and hold DIF for more than 2 seconds to enter differential mode.
✓Zero the Reading Before Testing – There is no separate ZERO key on this manometer. With the hoses disconnected and both ports open to ambient air, press and hold HOLD for more than 2 seconds to clear zero drift before connecting to the test points. A short press of HOLD freezes the current reading. Keep the meter away from vibration, strong electromagnetic fields, and rapid temperature changes while measuring. This zero adjustment is separate from a documented professional calibration.
✓Store and Review Up to 100 Readings – Short-press C/F to store the current pressure reading; press and hold C/F to leave storage mode. While reviewing saved data, short-press DIF to move forward one record or short-press MAX to move back one record. Press and hold UNITS for more than 2 seconds to clear all stored readings. This gas pressure tester provides on-device history review; the manual does not specify timestamps or data export, so it should not be presented as a data logger.
✓Detailed Pressure Specifications – The QX-1201 digital air pressure gauge measures up to ±20.68 kPa (±2.999 psi) with 0.001 kPa and 0.001 psi display resolution. Its stated accuracy is ±0.3% FSO at 25°C; repeatability is ±0.2% with a maximum of ±0.5% FSO, and linearity/hysteresis is ±0.29% FSO at 25°C. The measurement rate is 0.5 seconds, and the UNITS key cycles through 12 pressure units. Err0 indicates a reading above the positive range; Err1 indicates one below the negative range.
✓Connect Compatible HVAC Tubing – The two hose-barb ports are specified for 1/8-inch inside-diameter tubing, and one adapter is included with this product configuration. Some standard HVAC test ports may still need a different fitting, so check the hose size and port thread before starting. Seat the tubing securely and check the connection for leaks. This dual-port HVAC digital manometer measures the pressure difference between P1 and P2 when both ports are connected and DIF mode is selected.
✓Choose the Right Pressure Application – This professional air pressure meter can help with HVAC static pressure, filter comparisons, suitable low-pressure gas appliance troubleshooting, and laboratory vacuum checks within the QX-1201’s rated range. It is not intended for pool or spa high-pressure filters or measurements beyond ±20.68 kPa. Keep liquid, corrosive material, and debris out of the ports during the applications described here, and follow the equipment manufacturer’s testing procedure.
✓Backlit Display and 9V Battery Reminder – The 4.45 × 4.95 cm backlit LCD helps HVAC technicians read results in dim work areas. A short press of POWER while the meter is on switches the backlight on or off; after about 15 minutes without operation, the meter turns off automatically. This manometer uses a 9V battery and displays a low-battery indication when voltage drops to 6.8V or below. Replace the battery when indicated, and remove it for long-term storage.
✓Practical Controls for Service Calls – This manometer gauge combines single-port readings, P1–P2 differential measurements, reading hold, MAX/MIN mode, and recall of up to 100 saved results. The ABS housing is suited to careful, light-duty field use for residential and commercial HVAC work. Keep the pressure ports clean and dry, avoid carrying the meter by its hoses, and store it in a protective pouch to reduce the risk of drop damage. It gives professionals and experienced DIY users a straightforward gas pressure tester for routine diagnostics.
