Low-temperature 1-color Pyrometer
This classification includes one color infrared pyrometers measuring range is 250℃-2200℃. The one color pyrometers currently on market are mostly narrow-band pyrometers. Its principle of temperature measurement is to determine the temperature by detecting the radiant energy that occurs in a narrow wavelength range of an object. The temperature a pyrometer measured is the average temperature in an area, and the measuring result is affected by emissivity, lens contamination and background radiation.
To use 1-color pyrometer mode, the measured area of the object should be large (it can fully fill the target field of view) , object surface should be relatively flat (not curved), measurement direction should less than 30 degrees, and the physical and chemical state of the measured object surface should be stable (not in the process of oxidation, gasification or liquefaction) , the optical channel should with less dust and without blocking and attenuation.

**Test Theory**
Organophosphate and carbamate pesticides are among the most commonly used in agriculture, but many are banned for use on fruits and vegetables. These pesticides bind to acetylcholinesterase (AChE) in the body and are not easily separated, which inhibits AChE activity. This prevents the hydrolysis of acetylcholine, leading to nerve conduction issues, hyperexcitability, poisoning symptoms, and even death. Based on this principle, the enzyme inhibition method is used for detection. The process involves using a sensitive enzyme extract, such as butyrylcholinesterase, to measure changes in enzyme activity in food samples, thereby determining pesticide residues.
The YN-CLVI is the only instrument capable of testing heavy metals—such as chromium, cadmium, mercury, arsenic, and lead—in fruits, vegetables, and other food products.
