Product description

Use Series 1227 as a regular U-tube manometer to read high-range pressure on the right leg, or as an inclined manometer to read low-range pressure on the bottom leg. Simply incline manometer until fluid levels read zero. No spirit level required. Magnetic clips hold the gage in position on a steel duct surface. Most versatile and useful low cost manometer we know of. Designed for installation and servicemen. A sturdy, clear plastic manometer, it offers single, direct readings in two ranges: As a U-tube, it reads from 0 to 16" of water; as an inclined gage, it reads from -.20 to 0 to 2.6" of water. Model 1227M (Metric) is 0 to 400 mm water column as a U-tube and -5 to 0 to 70 mm water column as an inclined gage. "How-to-use" instructions are printed directly on the scale.

User questions & answers

Question:	What is the max PSI
Answer:	2psi
Question:	Can this measure inches water column? for gas valves and pressure switches
Answer:	Yes It measures in a couple of different measurements
Question:	When setting this meter to read for gas supply pressure, i want to get results in inches of wc (water column). what's the setting for this meter
Answer:	This is exactly why I purchased this meter. Hit the units button until the units are shown as In. (Inches are abbreviated in). Also make sure you are in differential mode (the diff button) so that the inlet attached to the gas is compared to the inlet exposed to the atmospheric pressure.
Question:	Will it measure in tenths of an inch
Answer:	It will measure .01” of H2O

User questions & answers

Question:	Could this be used to do zone pressure testing? Home Diagnosis tv show discusses the benefits of having matching pressure inside/outside the house
Answer:	It will only work on the return and supply duct if that is the question you are asking. So you will equalized pressure on your unit. Same amount of air coming in as going out. So nothing for outside the house with pressure.
Question:	Does it come with a pouch to keep it in
Answer:	I purchased this fieldpiece a couple of years ago and it did not come with a case or pouch. Very good pressure measuring instrument.
Question:	I need to measure a air chamber that will be between 1/2"-2" water column. it needs to be at 1.250" will this be accurate enough to measure
Answer:	spec states measure to 0.01 inches WC. if you need to 0.001inches WC will not be good for your measurements.
Question:	Full range? -wc to +wc
Answer:	Yes, it's spec'd at: * -60.0" WC to 60.0" WC range

User questions & answers

Question:	Can this be used for measuring pressure differential between lower and upper engine cowlings in light piston aircraft
Answer:	That depends on the pressure the switch on your furnace is operated at. This manometer measures very low pressure, most pressure is measured in lbs per sq in or PSI, gas pressure feeding into a furnace is very low ( below 1 psi) gas pressure in your home is measured in inches of water , think of counting dollars and needing to get closer to less than a dollar think of pennes 100 make a 1 dollar, same thing in less than 1 psi you have to switch to inches of water
Question:	can this be used or gas pressure
Answer:	Yes set on inches of water 11- 14 adjust propane regulator only
Question:	when using the left port, do you get a negative reading? mine does so I not sure if I got a defective unit
Answer:	If you are referring to the barbed adapter, it should be a 1/4" npt. You may need a bushing to size it to whatever outlet you are measuring. The two ports are used for differential pressures such as measuring air pressure drop through an air handler/furnace, etc. mWhen you are easuring gas pressure, one port stays open to read atmospheric pressure while the other (port) is reading inHg, KPa, bar, etc.
Question:	How long are the tubes
Answer:	No, the description shows 2 psi maximum. Your water system should be MUCH higher than this. The 55 water range is in inches of water column. It’s a completely different scale than psi. 55 WC (water column) is about 2 psi.

User questions & answers

Question:	Can this differencial manometer work as a traditional manometer if one places a cap on one of the barbs? What is the unit's accuracy and range for mmHg? (The pyleaudio webpage will not load otherwise I'd research these questions on my own
Answer:	I beleave it can. As long as you stay in specs. Reading other reviews, people are using it to set-up LP/Natural gas regulators. Remember it is only good for 10 lbs. psi. max.
Question:	dose this work for corbon monoxide
Answer:	I just checked out my manometer. What you are experiencing is normal and correct. Because it is capable of differential readings, you have both negative and positive sides of the sensor. Much like a volt meter. You would only use the left port while doing differential measurements. The right port would be used for all others. Giving you the proper pressure/vacuum reading that you would expect.
Question:	Does this measure the water coulmn in an oil fired boiler
Answer:	Don't have the item in front of me but recall the tubes as being roughly twice the length of the electronic unit itself, so at least 12 inches long, probably longer. I recall the tubes as basically folding in half to fit into the pouch that is provided with this product. This was a one-time-use product for me but saved me the cost of an HVAC home appointment that likely would have cost me upwards of $100+. My natural gas hang-from-the-ceiling garage heater had become horribly coated with carbon black from a misadjusted pilot light. I cleaned the unit, replaced the pilot and used this pressure manometer to adjust the pilot flame to specification. Pilots been burning for more than a year now with no carbon buildup. I found this gauge to be very precise and easy to use.
Question:	What is the resolution for inches of H2O or how many decimal place if any
Answer:	Thank you so much for your interest in our products. These readings are within the range detectable by the model 407910. You will have to check if these regulators require any standard for safety and if our meter reaches that standard.

User questions & answers

Question:	While doing a pressure check my gauge read 313 inwc which is around 12lbs it also displayed a code ofl anyone know what that means
Answer:	In the bottom of the section Product Description (big yellow-orange rectangle), it lists : package 1*USB Endoscope 1*Small hook 1*Magnet 1*Side audition 1*CD 1* User's Manual So I guess it does.
Question:	How do you display the readings in inches of water column
Answer:	Will not turn corners on its own. The camera needs to be taped to a drain snake or something flexible yet strong.
Question:	Does this unit come with a carrying case
Answer:	Yes. It should fit fine.
Question:	does the meter come with a hose kit
Answer:	I used this on a LP (liquid propane) system. It measures gas pressure, so it should not matter the type of gas. I suggest you consult the gauge manufacturer's web site to determine which gases are supported by this product.

User questions & answers

Question:	Hello. already returned 2 defective gauges. this looks as basic as t concept of in wc itself. will it accurately measure if my home ng pressure is
Answer:	In my opinion, yes, it will accurately measure 7" of gas pressure. It is as basic and as accurate as you an get, a simple water manometer. I've used mine to check gas pressure at a boiler and also at the inlet of a propane Generac generator.
Question:	Is there a standard type of fitting for connecting to the system? videos show people using diy fittings w/ stems. isn’t there a ready-made product
Answer:	I believe it has a standard fitting for relay driven gas valves like the ones used to control furnaces. If you want to measure pressure in a pipe, you need to build an adapter. Any good plumbing supply house or home center has the parts. They aren't expensive, and are reusable. Pro tip: pick up a roll of gas rated Teflon tape and use as directed. Tighten all joints securely.
Question:	Feeling a little dumb here. but how exactly does this hook up? (I want to check NG pressure out of a 1/2" black pipe
Answer:	Get a reducer 1/2"by 1/4" and conect the brass 1/4 that comes with this manometer and add water on your glass up to the 0 mark and open your gas and test your pressure.
Question:	Hooked up to wh conn. it read 7.5”. fired up furnace & dryer. it dropped to 6.5”. excellent reading. should i trust? seems so high for residential
Answer:	A good reading would be one above the minimum gas supply pressure specification on the water heater. I have seen a drop in pressure when the air heater comes on. This may have something to do with a shared gas supply branch pipe in my case. I think the gauge is accurate.
