There are MANY things that determine quality of water, common ones being: "Nuisance" Bacteria Not always harmful, but they do release iron and sulfur into the water during their life cycles, and form a biofilm on the well surfaces Disease-causing bacteria Most common are e. coli and coliform, but can also include fecal coliform and fecal streptococci ...

Very good question but you need to find out more information. The very first question on my mind is.. Where do they connect to ? if they are connected to anything else at all? A simple solution Find the starting point(A) and the end point(B) of either cable. Using a multimeter and a return cable* you test continuity of the cable. Either using Ohms = 0 ...

The gauge refers to the thickness of the steel, which is but one measurement of the quality of the stainless steel (the other main factor is the grade of stainless steel it's using) see: Steel Grades on Wikipedia. As for measuring the gauge , you can get a Sheet Metal Gauge online, or from your local hardware store.

“Water quality” is not one-dimensional … what kind of contaminats do you want to test for? If the answer is “everything” or “I don't know” then start by finding a reputable local lab, describe your concerns to them, and see what they recommend based on their knowledge of the water in the area. Once you have done a thorough one-time test, you will have a ...

A non-contact tester might give you a false-positive on the neutral in some cases. Try testing the outlet with an outlet tester which will indicate if the hot/neutral are switched or open. Alternatively you can use a multi-meter to test it. If you are in the US, you should get ~120VAC between hot and neutral, but 0VAC between neutral and ground if the ...

You can use your cable modem itself as the tool. Do a search for "[your modem manufacturer] cable modem diagnostics" and you'll find out how to access the modem's diagnostic page in a web browser. This will give you upstream & downstream signal levels and lots of other useful info. Here's a page with some information about a few different ...

The easiest way to test the output of a transformer is with a multimeter which can measure both volts and ohms. If the transformer is wired into the 120VAC, and the power is on, remove any wires on the 5V side and place the multimeter probes/clips on the two connection screws on that side. You need to read the transformer output rating to see if this is AC ...

A Hygrometer is used to test the level of Humidity. I'll bet that your levels are very high. High humidity can lead to health issues with mold groth, not to mention it can destroy your home. Things you can do: Vent the dryer to outdoors, a big source of the problem! Add a bathroom vent to the outdoors, not in an attic or other room! Run the fan for 30 ...

I wouldn't bother with making smoke—at least not initially. If this is in an apartment or condo, that might set off a smoke alarm. The surefire solution is to poke your head up into the attic with a bright hand held light. If you can't see the bathroom fan area from the access opening, you'll have to crawl through the attic until you are close ...

Continuity is "An unbroken electrical path in an electronic circuit or connector[1]". First thing, unplug the dishwasher or if hard-wired turn off the circuit breaker. Unplug the connector to the heating element and then test the contacts on the heating element. A heating element is a semi-conductive (typically coil) that creates heat as it resists the ...

I'm not a fan of the test kits. I recently had some mold issues and used a mail-in tape sample to test for mold. I did 8 samples for $50. I think 3 or 4 samples can also be done for lesser price. Here is the site I used: http://www.mold-control-on-a-budget.com/ (I'm not associated in any way to her but can vouch for her service and professionalism after ...

My thoughts on your first question would be to take a sample from a few different rooms, if you can see any differences between color/texture on the ceilings. From asbestos.com: If the material looks different (especially in color or texture) in different parts of the room, plan to sample each of those areas. For a ceiling surface in a large ...

I'm afraid any stand alone meters are going to be pricey. There are two types to measure RF signal level. One that you set on a frequency and read the power level at that frequency. The other is called a spectrum analyzer and shows a waveform of the power level across a range of requencies. That is what is really needed to see whats going on. I'd try to get ...

First of all, you need some SCIENCE! A multimeter measures one of three things: Current, Voltage, Resistance. Current (I) is the flow of electricity (how much water goes over the falls) In a one path circuit, the current is a constant throughout (i.e. ALL the water reaches the bottom) Voltage (V) shows how much potential energy the current is carrying. ...

If you've had problems with water damage in your basement before, there is a really good chance that you have mold. The downside is, it can be hard to detect mold on your own since it can grown within the walls or under carpet. You can buy a mold test kit from somewhere like Home Depot to check on your own. I would probably start there if I were you and if ...

I would recommend looking at the tutorial from SparkFun: How To Use a Multimeter. It is a bit specific to the multimeter that they sell.

The first source of information is the manual that comes with the meter. Most have a section on applications that explain the use of the various functions (voltage, current, resistance) in everyday repair situations. Your local library will also have a selection of books on electricity for homeowners that will have chapters on using a multimeter.

This makezine article links to this DIY-electronic project (which probably not what you want to spend a week building) but there's also a link to readymade alternatives like Mavromatic HM COM-100.

Just to answer the basic question; there is no such thing as a continuous stream "water quality monitor". Just like Gregmac and Vebjorn stated in their posts above, there are many elements which determine water quality. I can tell you based on working in power plants, and large physical plants we had (at only a handful of facilities mind you...) several ...

If we're just talking about hardness, there are water softeners that can measure the hardness in real time and adjust their regeneration frequency to match (for example, Culligan calls theirs an "Aqua Sensor". There are also realtime TDS (total dissolved solids) meters that are used on the output side of lab-grade filtration systems. I'm not sure if there ...
