Nitrite CHEMets® Visual Test Kit - Azo Dye Formation (NED) 0-0.1 & 0-1 ppm as N

Nitrite CHEMets® Visual Test Kit utilizes an Azo Dye Formation Method, where nitrite reacts with sulfanilic acid to create a colored azo dye. This allows for accurate and precise measurement of nitrite levels in an acidic solution. A primary aromatic amine and 4,5-dihydroxynaphthalene2,7-disulfonic acid are used to produce a pink-orange color, which is directly proportional to the nitrite concentration.  Results are expressed as ppm 
(mg/L) nitrite-nitrogen (NO2-N). To convert results to ppm NO2, multiply by 3.3. 

Range: 0 - 0.1 & 0 - 1 ppm as N
MDL: 0.005 ppm
Method: Azo Dye Formation (NED)

Very easy to use
Size: 12 Pairs / 24 pcs
I have an Onkyo audio/video receiver along with an Emotiva amplifier. Both have speaker "post" terminals which will accept banana plugs, OR I can connect the speaker wires by unscrewing the posts, poke the speaker wires into the terminals and then tighten the posts. The problem with poking the wires into the terminals and tightening the posts vs using banana plugs is that there is a risk of the wires touching the metal on the back of the chassis or touching other speaker wires, causing a short if one is not careful. With banana plugs, they simply plug into the back/top of the posts, eliminating the rsick of a short circuit. They can also be unplugged very easily if needed. Banana plugs are DEFINITELY the preferred way to connect speakers to an receiver or amplifier if they have post-style terminals. These particular banana plugs came in a package of 12 I believe. They were very reasonably priced, and simple to connect to the end of the speaker wires. Simply unscrew the banana plugs, use a small, standard jewelry screwdriver and loosen both of the set screws, insert the speaker wire, then tighten the set screws, and then screw the banana plug back together. The plugs have either a red band which would typically be used for your "Right" speakers, or a black band which would typically be used for the "left" speakers. The banana plugs insert into the top or front of the speaker terminal posts on the amp and receiver. They fit VERY snug, and so I did have to apply just a little bit of pressure in order to insert them into the posts, but once plugged in, rest assured they're not going anywhere. They are snug. I highly recommend these.

Heavy-Duty 4 AWG Cable With Flexible Insulation
Size: 10ft, Color: 4awg
I am satisfied with this 4 AWG cable. The insulation coating is soft, and the cable itself is very pliable, making it easy to bend and route into the configuration needed for installation. Despite the flexibility, it still feels like a heavy-duty cable designed to handle demanding applications. I am using this cable to provide the necessary amperage to start the generator on my trailer, and it performs as expected. I also like that the wire gauge and cable properties are clearly printed along the side of the insulation, making identification easy during installation or future maintenance. The cable arrived in good condition with no obvious odor from the insulation or packaging. Overall, this appears to be a quality heavy-duty cable that is flexible, easy to work with, and suitable for high-current applications.

True copper battery cables that are high quality
Size: 10ft, Color: 4awg
I love having heavy duty cable on hand for my cars. It's so nice to be able to make your own starter and alternator cables when restoring cars. These cables are 100% copper, not CCA (copper clad aluminum) like many others are. Copper is far superior for conductivity and handling higher loads. The rubber on the cable is thick and yet very flexible..it's clearly marked and seems very durable. I like to use a hydraulic crimping tool and then add marine grade heat shrink tubing with the adhesive inside of it to keep it as weatherproof as possible.

Excellent . Bought these to install a 5000 watt inverter . Arrived a little late but these cables are exactly as described. I needed 10 ft but ended up using like 9 ft. These are extremely flexible and of very good quality . Highly recommended and will buy again

Poor quality and false advertising in size
Size: 4/0 AWG 10FT Red & Black
A complete fraud. I ordered 4/0 but got 4 gauge. The description & picture was correct, but someone doesn’t know the difference in 4 gauge and 4/0. AND the jacket insulation was cheap and translucent, not solid color and supple/flexible. Poor product quality and completely misleading.
