*Easy to operate:

Adopting microprocessor technology, microcontroller control, and touch sensitive button operation for convenient and fast operation; The mass production of finished reagents ensures fast testing speed and low cost by opening the bottle and using it immediately.

IIThe connotation of speed testing technology:

In order to independently, inexpensively, and quickly complete soil nutrient determination work without being in the laboratory, the FM-TFY soil fertilizer nutrient rapid testing instrument is equipped with the following rapid testing techniques:

1. Manufacturing technology of photoelectric colorimeter: Colorimeters generally use filter photoelectric colorimetric technology. Due to the poor monochromaticity of the filter, the linear error is generally large. The national standard allows 3-8%. By improving the optical path design and intelligent microprocessor technology, the error has been reduced to 1-3%, achieving the accuracy level of grating spectrophotometers and reducing weight and cost.

2. Soil moisture measurement technology: To measure the nutrients of fresh soil, it is necessary to know the moisture content. A developed capacitive moisture sensor has been added to quickly measure the moisture content of soil samples.

3. Soil nutrient co extraction technology: The efficient N, P, and K nutrients in the soil can be extracted simultaneously at once, greatly simplifying the pre-treatment work and reducing the extraction time from half an hour to 5 minutes.

4. Reaction system anti-interference technology: In routine analysis, if a certain soil has special interference, experimental personnel can often add some treatment or choose another analysis method, while rapid testing does not have this condition. Therefore, rapid testing methods and reagent formulas must have strong soil adaptability and anti-interference ability, and the reagent formula is preferred.

5. Durable storage technology for finished reagents: Supplying finished reagents and enabling users to use them immediately after opening the bottle is an important way to improve testing speed. The storage period and analysis method selection of reagents, reagent formula design, reagent preparation process, reagent packaging, etc. The shelf life of supporting reagents has been extended to six months to one year.
