How many tests is the fluid in a CO2 tester good for?

The fluid in a CO2 tester is generally good for approximately 200 tests. This means that the tester can be utilized effectively for this number of applications before the fluid should be replaced. The reasoning behind this limit often involves the properties of the testing fluid, which can degrade or become less reliable after repeated exposure to the conditions and substances it is measuring.

Using a tester beyond its designated number of tests can result in inaccurate readings, which can affect diagnostic processes or maintenance work related to oil heat systems. It's important for technicians to be aware of the limits of their tools to ensure high-quality service and maintenance. This knowledge is crucial to proper testing protocols and helps ensure the efficiency and safety of heating systems.
