1、 Test strip-immerse-read-record-take measures

RQflex 20Compact and easy-to-use, making you feel like you're in a laboratory. Mainly used for raw material detection or residual monitoring after disinfection in the production process, accurate quantitative test results can be quickly obtained on site.

ReflectoquantThe system consists of a reflectometer and supporting componentsRQComposition of test strips. This portable laboratory solution provides you with all the necessary testing tools, mainly used for high-quality and low-cost on-site analysis and testing of food and beverage, soil, water and other samples.

1Intuitive navigation menu

The new Chinese menu is simple and easy to use, allowing you to access all testing methods, test results, and analysis quality assurance options, as well as customize various settings according to your own needs.

The Chinese display screen shows simple and easy to understand test methods and operation process diagrams, making it convenient for you to start testing directly and quickly obtain accurate and reproducible test results.

2Portable analysis

Lightweight and compact, like a mobile laboratory, it can directly analyze and test key indicators on site and obtain quantitative results. You can obtain test results within a few minutes, making it easy for you to monitor the raw materials throughout the entire production process.

3Barcode test strip with batch information calibration function

Each batch'sRQThe test strip packaging box contains a barcode with batch calibration function to ensure accurate and reproducible results. The accuracy can reach ± within the middle range of the testing range10%.

4The instrument supports analysis quality assurance function

Analyzing the quality assurance function（AQA）In the middle,RQcheckTesting kit and overall system monitoring（TSM）The process ensures that you receive accurate measurement results. Instrument baseline calibration is intuitive and simple, allowing you to always obtain reliable test results.

5Detailed testing methods and application instructions to meet your testing needs

We provide comprehensive and rapid instrument analysis solutions covering the determination of ammonia nitrogen, nitrate, and other substances, such as sugar content in chocolate, nitrite content in vegetables, or hydroxymethylfurfural in honey.

6Simplify your analysis through timers

To improve your efficiency, a timer with advanced warning functions can be customized according to your workflow to sound an alarm before the test strip preparation time ends.

7Supports multiple languages

English, German, French, Spanish, Portuguese, Japanese, and Chinese are optional.

2、 Application

ReflectoquantThe application instructions provide specific steps for sample preparation and detailed information on how to measure various parameters in agricultural, food and beverage, or disinfection residue control processes.

1Agriculture: Controlling Nutrients in Soil and Plant Products

Like nitrogen, phosphorus is also a nutrient element that plants require in large quantities during their growth process. Overfertilization may occur in agricultural production, so analyzing these parameters is crucial.

2Disinfection residue control:0.1%Peroxyacetic acid is sufficient to kill bacteria, viruses, fungi, and spore forming bacteria in the shortest possible time

Therefore, it is often used in infectious low-temperature disinfection processes such as beverage packaging bottles. Complete disinfection residue control includes analysis within high and low concentration testing ranges.

3Food and beverages

（1）Rapid quantitative analysis of hydroxymethylfurfural content in honey

The freshness of honey can be detected by measuring its hydroxymethylfurfural（HMF）Determine based on the content.HMFIt is an organic compound produced during the dehydration process of fructose, such as heating for packaging convenience. Almost undetectable in fresh honeyHMFAfterwards, the agreement will be made2.3mg/kg/The annual rate of increase depends on the storage temperature andpHValue).

21At ℃,HMFThe content can increase to within just one year20mg/kg.

（2）Determination of V in food and beveragesC

VC(Ascorbic acid) is a parameter that often needs to be tested in many food and beverage industries. The reduction of this ingredient will cause a decrease in quality and taste, so it is necessary to test its content.

（3）Detecting Acrylamide

In fried or baked goods such as potato chips, the reaction between asparagine and reducing sugars (fructose, glucose, etc.) may produce acrylamide, which is considered a toxic carcinogen. Therefore, the reducing sugar in potatoes should not exceed the allowable amount.
