- Here’s how to use your Magnehelic Gauge: 1) Prior to cleaning the dryer vent, install our SmartTap Fitting in the transition hose (see pic to the right). Using the same tubing from the LintAlert, connect the SmartTap Fitting to the High Pressure barb on the magnehelic gauge.2) Turn the dryer ON and take note of the high pressure reading on the gauge. 3) After cleaning the dryer vent, turn the dryer back ON and see how much the back pressure has been reduced.sing the same tubing from the LintAlert, connect the SmartTap Fitting to the High Pressure barb on the magnehelic gauge. 2) Turn the dryer ON and take note of the high pressure reading on the gauge. 3) After cleaning the dryer vent, turn the dryer back ON and see how much the back pressure has been reduced.

How to Measure Air Pollution for a Science Fair Project How to Measure Air Pollution for a Science Fair Project. Pollution is one among the major problems of today’s world and air pollution is one root cause of many environmental issues. You can use a magnifying glass for this purpose as the dust particles are too tiny to be seen with necked eye. 2  Count the number of dust particles carefully stuck to the Vaseline in each square and note them down on a note book. 3  Use the number of dust particles sticked to the squares as a proof of air pollution.

Cliches A negative pressure gauge is used to. test evap systems where the on-board system uses vacuum to test for leaks. This is also the primary gauge I use to test different evap systems. This photo shows a typical evap system testing setup that uses a hand-held. vacuum pump with an H. 2O vacuum gauge teed into the test line. The in.-Hg gauge. (attached to the pump) is not used at all. The lines to the H. 2O gauge and hand.

- Posts. 3,659. Buy a depth gauge (compact one) used for diving that has a MAXIMUM needle on it. Attach it to the line with a carabiner clip and let it slide down the line to the lure. Put a rubber band on the line at the spool-then reel the gauge and lure in to see where it was. Then if you want it deeper let the line out further than the rubber band and vice-versa. I know the gauge has a little effect on the depth but it is very minimal especially during trophy season when you are running HEAVY stuff. 03-27-2007, 04:01 PM #8.

Pulling A Good Vacuum Equals $$$ For The Contractor A micron gauge measures the amount of air or “noncondensables” and moisture in a system. The unit of measurement used is a “micron.” The gauge is placed between the vacuum pump and the middle port of your manifold set. The lower the micron reading, the deeper the vacuum. The deeper the vacuum, the lower the amount of air and moisture in any given system.

How to Use a Manifold Gauge Set How to Use a Manifold Gauge Set. A manifold gauge is used to diagnose and correct an air conditioning unit that is not working (cooling properly). Refrigeration manifold sets check the pressure of the refrigerant inside the system.Follow these instructions to check your A/C. The service hose on the manifold gauge set must have manual or automatic backflow valves at the service connector ends to prevent refrigerant from leaking. 2  Connect the blue hose to the low pressure port on the A/C. 3  Connect the red hose to the high pressure port of the A/C.

Tips From The Pros If you want to use a 22 gauge needle to do a hand draw using a separator tube, release the vacuum in the tube. It will allow for 1/2 of the tube to be filled with blood, and will also decrease the possibility of a hemolized specimen, and a hematoma on the patients hand! -- Michael.hen you insert the needle into the patient's arm it is good practice to switch the hand that's holding the barrel. This way the dominant hand is the one inserting, and changing the tubes. This stabilizes the needle holder/barrel better and prevents the needle from moving each time the tube is changed. -- Natalie.

- A2 build, and attach the compact ACOG to the carry handle, like in the pic. I would prefer more magnification than 2x though, I looked at a compact last night in a local sporting goods store and it was a 4x32 with the red chevron and .223 ballistic reticle. I'm a little confused because SWFA only carries up to 2x.

- Amp probe meters are very easy to use, and you do not need to be an electrician in order to use one correctly. Depending on the type of current and wire you are testing, you will need to set the amp probe to a 0-10 or 0-20 amp scale. A local electrician could advise you about setting your amp probe meter.
