MEATER's internal sensor is accurate to 0.5 of a degree celsius. If you suspect your MEATER is giving incorrect internal readings it is worth considering that probe placement may be the issue. The internal sensor pictured above should be inserted into the thickest part of the meat. If it is not then the section where the internal sensor is sitting may have hit your target temperature; but the core of the meat might not! Establishing proper probe placement is essential to producing good quality results with MEATER.
If you still think that your MEATER is giving incorrect internal temperature readings you can test it at home by boiling a kettle and pouring some water into a cup. Stir the water well and insert the MEATER probe. If you have another thermometer for comparison then add this to the mix. If not you should be looking at an accurate consistent boiling temperature of between 95 and 100c every time you try this.
If your internal temperature is nearing close to that of the ambient temperature, the ambient may not display/displays a '-' symbol. We are constantly looking for ways to improve our algorithms and do apologise for any inconvenience this may have caused/will cause during your cook.
Moving forward from this, to test the ambient sensor is working you can do a simple test at home:
If the ambient sensor does appear then we know that the probe is working correctly.
The ambient temperature MEATER provides can be affected by many variables. It is important to remember that rather than measuring the temperature of your grill/smoker/oven etc. It is measuring the temperature directly at the point of the black ceramic tip of the probe.
Most cooking devices will differ in temperature largely based on the location of MEATER, which is important to take into account when trying to compare the temperature readings of MEATER with another thermometer, or another MEATER probe itself. Often the temperature is very different at and near meat. The benefit of the ambient sensor on the MEATER Probe is that it can identify whether your meat is at a hot or cold spot and if the ambient temperature is consistent across all of the meat you're cooking.
For example in a smoker, just the difference between the gauge's position and grates can vary between 20-40F depending on how hot it is running. Having the ambient sensor where the meat is can help identify this temperature difference.
Probe Direction/Location: We strongly recommend not having the ambient touching any hot elements or metal that may get hot over time. Please also make sure that this part of the probe is not inside the meat, or too near it as it can affect the temperature readings. Ideally, the MEATER Probe should be submerged into the meat up to halfway between the insertion notch and the ambient tip.
Cooking Apparatus Accuracy: Cooking appliances, like ovens, operate on wave temperature; meaning if you set your oven to 200c, the temperature will likely fluctuate above and below this target in a wave-like pattern as it turns the heating element on and off in an attempt to maintain the correct temperature. This is something that you can expect to see in your cook graphs when cooking with MEATER, showing the correct behaviour of your cooking appliance in heat.
