1. How do I know when the Fyrite fluid needs to be replaced?
2. What can I do if the fluid level is below the zero mark on the sliding scale?
3. How long should the fyrite fluid last?
4. How many times should I squeeze the aspirator bulb on my fyrite?
5. What does it mean if my Fyrite reading is too high?

After a test is completed, invert the sample bottle two additional times.  If the level of the liquid rises, the fluid needs to be replaced.

Occasionally, enough water will evaporate from the fyrite fluid to reduce the volume below the zero mark on the scale.  Simply add a few drops (it doesn't take much) of water to the fluid.

When measuring CO₂ (red fluid) at 10%, the fluid should be capable of 300 to 350 tests.

The O₂ fluid (blue fluid) at 10%, the fluid should be capable of 100 to 125 tests.  If the O₂ fluid becomes green in color, it should be replaced.

The aspirator bulb should be squeezed a minimum of 18 times whether it is measuring CO₂ or O₂.

Make sure the wool material in the filter chamber is damp.
