SKU : Propylene Glycol Coolant Hydrometer (Tester )

Hydrometer c\w unabreakable transparent perspex tube

Easy to read indicator and designed for modern Ethylene Glycol antifreeze
Number of floating discs indicates level of antifreeze protection.
Tests at hot and cold temperatures and reads in Celsius and Fahrenheit.
Floating orange disc shows over protection and loss of efficiency.
50/50 mixture - the coolant will boil at 107 deg C (228deg F) and freeze at -37deg C (-34deg F)
70/30 mixture - the coolant will boil at 135 deg C (276deg F) and freeze at -64deg C (-84deg F)
Solution with more than 70% antifreeze will give less protection.
Pure antifreeze will freeze at -21C (-6 F)

Note! Distilled or deionized water should be used for Ethylene glycol solutions.
City water is often treated with chlorine, which is corrosive, and should be avoided.
One of the best method to determine if the coolant is properly mixed is to measure the strength or concentration of the antifreeze with a hydrometer.
After checking then you can safely decide to add more antifreeze or distilled water

Good quality for a good price!
Size: 6 Gauge 15FT, Size: 6 Gauge 15FT
Good value for the quality of these copper cables. Cut them to the length I needed and put a copper eyelet on one end. Wire size works good between my Victron solar charge controller and the batteries. Wire gauge will be able to handle the wattage much better than what I was using. They look much more professional than the old cables I was using also!

Be safe and always calculate the gauge wire are you need, don’t cut corners.
Size: 4 Gauge 10FT
Good quality solid copper 4 Gauge wires in red and black. Avoid aluminum wiring that has copper plating so looks like solid copper but can be dangerous if used in heavy load applications. Copper is expensive but required if amperage is high.

Durable insulation and pure copper not that cca bs
Size: 1/0 Gauge 5FT
Good quality. Solid copper, not that cca bs. Stiff and durable insulation. Used for big 3 car audio grounds on high output alternator. Great results. Will mention that it’s not as thick as some other brands but not by much. Terminals still crimped tightly with 1/0 gauge
