You have noticed the appearance of condensation in the thermometer of your kamado and are wondering about its origin? This phenomenon is generally related to humidity and temperature variations to which ceramic barbecues are regularly exposed. In most cases, this condensation is temporary and does not affect the accuracy of the thermometer or the quality of your cooking.

WHY IS THERE CONDENSATION IN THE THERMOMETER OF MY KAMADO?

Like any device used outdoors, a kamado is subject to changes in temperature and variations in humidity. When humid air gets inside the thermometer, the temperature difference between the dial and the outside environment can cause condensation to form.

Steam often appears after a rainy period, during the first ignitions of the season, or during long low-temperature cooking. In these situations, it is a natural phenomenon comparable to what can be observed on the windows of a house or on the windscreen of a vehicle.

STEAM IN A KAMADO THERMOMETER: IS IT NORMAL?

In the vast majority of cases, yes. Occasional light condensation is perfectly normal and does not necessarily indicate a fault with the thermometer.

Kamado thermometers must withstand demanding conditions. They are continuously exposed to heat, smoke, humidity, and sometimes the elements. Therefore, it is not uncommon for a veil of steam to appear temporarily behind the dial glass before disappearing during subsequent uses.

When the condensation is light and temporary, it generally has no impact on the accuracy of the displayed temperatures.

WHAT SIGNS SHOULD ALERT YOU?

If the steam becomes permanent or if water droplets remain visible several days after cooking, it may be useful to monitor the evolution of the phenomenon. Particular vigilance is recommended when reading the dial becomes difficult or when the displayed temperatures seem inconsistent with the observed cooking conditions.

In this case, the seal of the thermometer may have been compromised and a check may be necessary.

HOW TO REMOVE STEAM FROM A KAMADO THERMOMETER?

The simplest solution generally involves raising the temperature of the kamado for a sufficiently long period. Cooking or heating up to between 200 and 250 °C often allows for the natural expulsion of moisture present in the dial.

It is also advisable to pay attention to the storage conditions of the kamado. Even though it is designed to remain outside all year round, using a quality protective cover and choosing a well-ventilated location help limit moisture accumulation.

In most situations, no special intervention is necessary. After a few heating cycles, the condensation naturally disappears.

CAN STEAM AFFECT THE DISPLAYED TEMPERATURE?

Slight condensation generally does not affect the accuracy of the thermometer. As long as the needle remains fluid and the reading remains clear, the displayed temperatures remain reliable for cooking control.

However, if a significant amount of water accumulates inside the dial for a long period, the mechanism may eventually be affected. This situation is relatively rare but deserves checking if it persists.

WHEN SHOULD YOU REPLACE THE THERMOMETER OF YOUR KAMADO?

Replacing a thermometer is generally only considered when condensation becomes permanent or when measurement performance is no longer satisfactory.

If the dial remains continuously fogged despite several high-temperature cooks, if the needle reacts abnormally, or if the indicated temperatures seem inconsistent, it may be wise to consider a replacement.

You can also perform a simple check by immersing the metal probe of the thermometer in boiling water. The displayed temperature should be close to 100 °C. A significant discrepancy may indicate a malfunction.

HOW TO AVOID CONDENSATION IN A KAMADO THERMOMETER?

Although it is impossible to completely eliminate the risks of condensation, certain good practices can help reduce them. A kamado protected by a suitable cover, placed in a properly ventilated area and used regularly will be less exposed to prolonged condensation phenomena.

Regular temperature increases also help eliminate the moisture accumulated inside the barbecue and its accessories.

CONCLUSION

The occasional presence of mist in a kamado thermometer is a perfectly normal phenomenon related to humidity and temperature variations. In the vast majority of cases, this condensation naturally disappears after a few uses and does not affect the accuracy of the thermometer or cooking performance.

If the mist persists for a long time, if it hinders the reading of the dial, or if the temperatures become inconsistent, it is advisable to check the condition of the thermometer and consider replacing it if necessary.

FAQ: MIST AND CONDENSATION IN A KAMADO THERMOMETER

IS IT NORMAL TO HAVE MIST IN A KAMADO THERMOMETER?

Yes, occasional light condensation is perfectly normal. It is generally caused by the temperature differences between the inside and outside of the thermometer.

WHY IS MY THERMOMETER FOGGED UP AFTER RAIN?

The humidity present in the air can condense inside the dial when the kamado is reheated after a rainy episode.

CAN STEAM DAMAGE THE THERMOMETER?

Occasional condensation generally does not damage the thermometer. Only persistent humidity over a long period can eventually affect its mechanism.

HOW TO REMOVE STEAM FROM MY KAMADO THERMOMETER?

The most effective method generally involves raising the temperature of the kamado to naturally expel the humidity present in the dial.

DOES CONDENSATION AFFECT COOKING TEMPERATURE?

No, slight steam generally has no impact on the accuracy of the displayed temperatures.

WHEN SHOULD A KAMADO THERMOMETER BE REPLACED?

Replacement is recommended when the steam remains permanent, the dial becomes difficult to read, or the indicated temperatures seem inaccurate.
