WHAT IS AN INFRARED THERMOMETER AND HOW DOES IT WORK
Prior to using an infrared thermometer for measuring the body temperature, all you need to do is make sure you have the right one at hand. In order to detect the body temperature with the intent to get quick and accurate reading, you should use a high-quality (ideally FDA-certified) infrared thermometer specially for medical use.
This is because medical infrared thermometers cover a limited temperature range of around 10°C/20°F (Suitable for detecting the body temperature whose range is about 32..43°C/90..110°F), which achieves higher accuracy (accuracy tolerance of ± 0.3°C/0.6°F).
Besides, when selecting your infrared thermometer, you need to pay close attention to the response time. Always choose an infrared thermometer gun with quicker response time (better to be fewer than 1.5 seconds). This is because fast response time helps your gun to get the body temperature more immediately, leading to more accurate reading.
Insert the stem of a probe thermometer into the thickest part of the food, or in the centre of the food if the food is even in thickness. If the food is liquid (e.g., stew or soup) stir it to make sure the heat has been evenly distributed before inserting the thermometer in order to get an accurate temperature reading.
BRIX REFRACTOMETER
To test the sweetness of dragon fruits, you can use a little tool called the BRIX refractometer (or Br for short). It measures the sugar content in the juice. On this Brix scale, Brix 1 means there is 1 gram of sucrose sugar in 100 grams of juice. ... The trick is no flesh, no seeds, and only the juice.
