UNI-T UT366A Digital Differential Pressure Manometer

UNI-T UT366A Digital Differential Pressure Manometer in Sri Lanka

Dual-Input Digital Manometer with LED Pressure Indication & Wind Speed Measurement

The UNI-T UT366A Digital Differential Pressure Manometer is a compact, dual-port instrument capable of measuring both gauge pressure and differential pressure independently through its P1 and P2 inputs. With a wide measurement range of ±15.00 kPa, built-in LED positive/negative pressure indication, and support for 13 selectable engineering units, the UT366A is ideal for HVAC commissioning, gas pipeline testing, filter pressure drop monitoring, and plumbing pressure checks in Sri Lanka.

Explore our full range of Differential Pressure Gauges & Manometers — all brands, types, and ranges available in Sri Lanka.

Paired with an optional pitot tube accessory, the UT366A also functions as a pitot tube manometer for air velocity measurement — making it a versatile dual-purpose instrument for ventilation engineers and air balancing technicians. Its 1-metre drop-tested housing, FSTN backlit LCD, and MAX/MIN/AVG/HOLD functions make it equally capable in workshop calibration benches and demanding field environments.
