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 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

required tool for crankcase vacuum/pressure diagnostics.... helped to diagnose and resolve a restricted pcv orifice on an Ecotec

I got this to double check the manometer on the pipe to the radon fan. I will be handy for HVAC tests.

As an electrician, my expertise typically lies outside the realm of measuring air pressures. However, while working on industrial burners, I encountered a situation where verifying the safety circuit became paramount. In that instance, the precision of this meter not only proved invaluable but also justified its cost with just a single use. Its capabilities transformed a routine task into a critical safety check, ensuring that everything operated smoothly and securely.

Works perfectly in setting upto gas pressures in gas valves. This is a MUST have device to keep your installations safe and operational.

Klein makes a good tool 85% of the time. This one did not disappoint. Compact & accurate tool. Comes with nice zip up fabric case that has a compartment for tubing and connectors needed to use the tool. Recommended.

It reads in hundreds. It does seem to struggle to hold zero. Overall, the product Is OK. I’ve used it several times it works OK. I guess you can attribute the price to the brand name.

Perfect size, easy to use and handy magnetic back.

Perfect for working on the job

work well for my as Gas tech using manometer for adjusting or checking gas pressure.

This manometer is a great size, easy to see when lit up and easy to use.

I am not a gas man but I did inquire with a professional before buying this and was told this is the brand they all use. The meter was easy to use and understand and got the job done.
