Buyer's Guide: Co2 Tester

Co2 Tester

Model No. : SD-1025E is one of two recommended CO2 testers that comes with the kit. Designed for checking leaks in cylinder head without unscrewing engine block by testing the presence of CO2 in coolant, radiator, and fan cooling lines by filling the bottles with test solution. The leak testing is done by spraying the test solution on to the leaky parts, such as cylinder head, radiator fins, and fan belt. The other option is by using an external method, which is recommended for large diameter holes or cracks, and for checking for leaks at unusual places.

The other tested and recommended CO2 tester is model No: SD-1025H. Ideal for checking the level of carbon dioxide content in the radiator and fan belts without disassembling the engine block, this tester uses a carbon monoxide sensor to detect the amount of carbon dioxide dissolved in the coolant. There is an LED indicator located on the lid of the bottle which flashes when the level of carbon dioxide is detected. This product is not suitable for detecting leaks in your engine because the detection of carbon monoxide in the coolant is based on a different principle than the detection of carbon dioxide in the radiator. You can use this product for checking the level of carbon monoxide in your air conditioner only if it has been certified to prevent and stop excessive air conditioning unit operation.

The other widely used CO2 tester is Co2 gas monitor. This tester is made to detect the levels of carbon dioxide in the exhaust from the tailpipe and other emissions. This is the best for checking the level of co2 because all the other testers are based on the same principle as to how they detect the level of co2. To know the exact readings of co2 tester you need to use CO2 analyzer to check the levels of co2.

The main reason why you should use this analyzer when checking for a leak in your auto is that by measuring the amount of co2 gas in the air you can easily find where the leak is. You will not be able to find it if the gas is still rising up in the air. Most of the times the location of the leak is not very clear but you can find it with the help of this device. The other thing which is good about this analyzer is that it does not produce any harmful gases.

If you find a leak in your automobile then you need to replace it right away. But before you replace the faulty one there are certain things which you have to consider and remember. The first thing that you have to keep in mind is to find out the exact location from where the malfunction has occurred. If you are able to find the exact location then you can use the Co2 tester to determine whether the problem is air leakage or not.

The other thing which you have to keep in mind is that you should use the co2 tester only for the purpose of detecting the leaks. There are various other methods which are also available which can help you detect the faulty wiring. When you use the carbon monoxide analyzer you can easily find out whether the car has been contaminated with this toxic gas. You can make use of the Co2 tester and other related accessories in order to maintain the engine of your vehicle properly.

There are some precautions which you have to follow before you start using the analyzer. You should always wear gloves when you are carrying out the test. It is because the emissions of this poisonous gas are quite hot. So you have to make sure that you wear some protective clothing on your hands. There is no other risk of causing harm when you are trying to perform this test.

You can easily carry out the test yourself. But if you do not have the time to perform the test yourself then you should get a professional lab to carry out this task for you. If the tester is reliable then it will show 100% results as early as possible. You should make sure that you choose the right place to carry out the co2 testing. The best place to find a co2 tester is a reliable lab which is a part of a manufacturing company.
