Klein Tools ET180 Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight

Great if you need to measure differential pressure. I use mine for checking building pressure at exterior doors. The directions can be a little confusing. You have to know what connection port is for high and which is for low. I used a label maker to put stickers on each port so that I didn't constantly have to consult the manual. Works well enough for routine measurement tasks. If you need something precise, you probably need to purchase a device that can be routinely calibrated by a testing lab that can certify the device at least annually.

Works perfect

Works as it should. I've had it close to 12 months and works fine. Of course you'll need different hose/tubing options for your job site. I use it for gas appliances and the ports are around 3/8 or larger. Still a great tool to have dual ports inh20 ,zeroing feature, magnetic
