Digital Manometer, Professional Air Pressure Meter, Differential Pressure Gauge HVAC Gas Pressure Tester （Measuring Range: ±20.68 kPa）

Working great

Excellent device. Works as advertised.

Reasonably priced. Works good so far. Not sure how long it will last since I've only had it for a couple weeks.

Returned meter as it was not accurate. Got no reply from mfg for support.

Worked just like it said it would.

Ck has pressure at house worked great

Purchased this product to check pressure differential between rooms during HVAC operation. It works good for this purpose; not sure if it is sufficient if more precise readings are required. The included tubing is very short, so you may need to get some longer ones. I would recommend this instrument to any home DIY'ers such as myself.

Ports are to small for HVAC use and readings are not accurate.
