AR1890P2, Digital Air Pressure Manometer to Measure Gauge & Differential Pressure ±13.79kPa / ±2 psi / ±55.4 H2O with pair of 304 Stainless Steel Static Tube 5.13" x 2.34" Length

Half the price but still got the job done. Highly recommended!!This manometer is recommended by a mechanic I know. Half the price of other brands but yet works as good. Seller has got different shapes and types of probe to fit with this device. They are sold separately and you can choose according to the measuring environment.There are many scales and units to choose from, although I am using only some of them. When using both two tubes, it displays the pressure difference. This help me check my furnace, air-conditioner and gas appliances without spending $$ on service calls!It used to be sold stand alone with soft plastic tubings. Packages with stainless steel probes offered recently and making it an even better deal. Minimal packaging which is great for the earth. Fast shipping. Recommended for sure!

Great budget tool to have around house to troubleshoot airflow. Used it extensively to map a pressure field under the basement floor for radon mitigation. Did some HVAC balancing when added additional air return vent and extra supply floor vent in a small bathroom.

Worked well for about 2 months, Now it has phantom readings that are not accurate.

The plastic hoses could be a little longer and the storage case a little bigger but it did the job. For the price it is worth it.

Easy to use, very accurate, just wish it came with longer tubes. I got a second as backup, paid for itself 1000 times over in duct corrections and changouts. Saves clients the headache of broken down units due to static related failures.

This is my second one. This model is good for my job as air-con mechanics. Value for money with high accuracy. The new tubes are making the manometer perfect.

Works fine but other tubing needs to be purchased what is provided is worthless

It does the job, good price but hoses are to short
