Product OverviewThe UNI-T UT366A is a precise, handheld digital manometer designed to measure positive, negative, and differential pressure in gases. It is an essential tool for HVAC technicians, industrial process controllers, and laboratory researchers who need to verify gas flow, pressure drops across filters, or the operation of gas appliances. Its dual-input capability allows for simultaneous differential pressure measurement, making it ideal for troubleshooting balanced ventilation or pressurized systems.Key FeaturesDual-Input Measurement: Equipped with two input ports, allowing for the direct measurement of differential pressure ($P1 - P2$) between two points.Versatile Unit Selection: Supports a wide variety of pressure units—including kPa, psi, kg/cm², oz/in², bar, mbar, inHg, mmHg, inH₂O, ftH₂O, and cmH₂O—providing flexibility for global and specific industrial standards.Precision Diagnostics: Features a high-accuracy sensor designed to capture minute pressure changes, with a "Data Hold" and "MAX/MIN" function to track stability or peak pressure events.User-Friendly Interface: Large backlit LCD for visibility in dark maintenance areas, with an auto-power-off feature to extend battery life.Rugged Design: Compact, ergonomic housing built to withstand the rigors of field work, including an adjustable response time to stabilize readings in fluctuating environments.Technical SpecificationsFeatureSpecificationBrandUNI-TModelUT366APressure Range±15 psi / ±103.4 kPaAccuracy±0.3% FSO (at 25°C)Repeatability±0.2%Response Time0.5sDisplayBacklit LCDPower Source3 x 1.5V (AAA) BatteriesDimensions134 x 65 x 28 mmWeightApprox. 130g
