The TA532A High Accuracy Digital Differential Pressure Meter is a professional portable measuring instrument designed for accurate gas pressure and differential pressure measurement. Equipped with a high-performance low-pressure pressure sensor, it provides precise differential pressure testing with a measurement range of ±40.00kPa. The instrument supports 14 selectable pressure units, including Pa, kPa, mbar, bar, and psi, meeting different measurement requirements and international standards. This digital differential pressure tester integrates multiple professional functions, including zero calibration, differential pressure calculation, data hold, maximum/minimum/average value measurement, high and low pressure alarms, and data logging. With a built-in USB communication interface, the meter can be connected to a computer for data acquisition, export, analysis, and long-term monitoring. The included silicone pressure hoses allow quick connection to air ducts, equipment ports, and testing points for efficient field measurements. With high accuracy, portable design, and powerful data management capabilities, the TA532A digital differential pressure gauge is widely used in HVAC systems, ventilation duct pressure testing, air handling unit commissioning, air filter resistance measurement, cleanroom differential pressure monitoring, hospital operating room pressure verification, industrial equipment inspection, boiler and combustion system testing, compressed air systems, fan performance testing, building ventilation acceptance, laboratory fluid experiments, and third-party engineering inspection applications. Whether used for installation commissioning, preventive maintenance, engineering acceptance, equipment calibration, or scientific research, the TA532A differential pressure measurement instrument provides a reliable and efficient solution for gas pressure and differential pressure testing.
