  • WORRY-FREE SHOPPING: With the Pyle PDMM01, we are confident of the quality of our product
Extremely flexible and very cost effective product.

My service department calibrates all kinds of hospital equipment. We had been carrying around a large box filled with many different gauges some costing over $100 each. This device is small, easy to read, and allows us to check every pressure or vacuumn measurement needed in our serive calls', except some high PSI procedures for which we carry an external gauge. HIGHLY RECOMMENDED.

Nice product

Does a good job for what I needed at work.

Holds its own

I am a HVAC service tech this manometer holds its own against 150$ fieldpeice and UEI manometers side bye side in the field I've compared all 3 for a year now my company owns the fieldpiece and came with my van after I purchased the Pyle meter the UEI was given to me bye and older tech that was moving on after I bought the Pyle also the Pyle is deff the flimsiest of the 3 and seems to search and flutter a little more than the other two but in the end recorded the same measurements as the other two and actually has way more units of measurements than the other two and is at least 100$ less than the UEI and the fieldpeice. I've used all three to check gas pressure , static pressure and pressure difference in many different systems and situations and all 3 are great manometers I currently use the Pyle in my service bag and use it to trouble shoot because of the many unit of measurement options and don't mind banging up the meter that's the cheapest in price the fieldpiece is in my testing bag for with my start up and commissioning tools and the UEI sits in the front of my truck as a back up or if I need to grab one quick . Overall I would recommend this manometer to any one in the Hvac field

You'll need this to service to your own propane equipment.

I use this to adjust propane pressures from our 500gal tank and then at each appliance. Easy to use, very accurate with good features for peak pressure, etc. Came in very handy when we rebuilt our 12KW standby generator. Worth every penny if you service your own propane equipment.

quality product , reasonably priced.

i needed to purchase a reasonably priced meter to use only one time to test the draft on my harmon P-68 pellet stove. after pricing very expensive draft meters designed only for this purpose i found the PYLE model # PDMM01 manometer. it accurately measures both positive and negative pressure on an easy to read LED screen. this is a reasonably priced , quality , easy to use product -- it comes with connecting hoses , fittings , carrying case and even the battery. i only needed to purchase a rubber tapered cone shape adapter that is used for automobile vacuum testing to connect the meters provided hose to the test port on my stove. after using the meter just one time to accurately adjust my stove without guessing -- the stoves never worked so good and the heat output has almost doubled and even saves on the the amount of wood pellets used . great product , basically paid for itself in just one use.

Great kit

I bought this one instead of one of the other similarly priced manometers because it came with the extra attachments I needed. I used it to install my pool heater and diagnose a problem I was having. It was simple to use and helped me pinpoint my gas supply problem. Especially for the price, it was money well spent for the amateur occasional user like me.

Good Manometer.

If you have a wood furnace like me I would highly recommend this. I use it for testing my chimney exhaust water column when installing my chimney pipe to make sure that I am getting a good burn and the gases are flowing at the right rate.

automotive use

I bought this to use for work to primarily measure crankcase pressures, has other uses as well. multiple scales including the one which was importance for my job. Update. 07/15. Have used this tool many times now and it is a great time saver. Been a good purchase for my diagnostic tools and recommend highly.. update 3/1/16.; meter works so well, it has impressed co workers, so much so, they have begun to purchased their own from pyle.

This is a good meter I was able to set the gas pressure ...

This is a good meter I was able to set the gas pressure in my Furness with it (Inches of water) I cross checked it with a direct low pressure gage that reads Inches of Water, They both read the same. The Digital gave the reading Fraction between increment's which nice if you fine tuning the gas pressure. Its a Good Meter cant beat the price.

Good Value for the Price

Good value for the price. Very sensitive, and plenty of resolution, I can't attest to the accuracy, because I haven't checked that. I noticed you need to be careful about not handling the plastic tubes, because that heats them up, and significantly affects the readings. After installing the tubes by hand, I needed to wait about 30 minutes before the readings stabilized. Then be sure not to handle them again while taking readings.
