Portable Pesticide Residue Detector

Scope of Detection

Mainly used for rapid detection of organic phosphorus and carbamate pesticides in fruits, vegetables, tea, grains, water, and soil, especially suitable for on-site law enforcement by food safety testing institutions at all levels. In addition, it can also be used for on-site testing in fruit and vegetable tea production bases and agricultural wholesale sales markets, as well as safety rapid testing in restaurants, canteens, and household fruit and vegetable processing

Instrument Principle

Detection principle: Using a microcontroller to control parameters such as temperature and time, combined with biochemical reactions for semi quantitative detection of organic phosphorus and carbamate pesticides in vegetables, fruits, and other foods

◆ Biochemical reaction principle: Acetylcholinesterase (white tablet) in the rapid test card can catalyze the hydrolysis of indophenol acetate (red tablet) into acetic acid and indophenol. Due to the inhibitory effect of organophosphorus and carbamate pesticides on acetylcholinesterase activity, the color development after catalytic hydrolysis changes. Therefore, based on the color intensity of the results, the residual situation of organophosphorus or carbamate pesticides in the sample can be determined

Instrument Features

◆ 12 channels, fast detection at the same time, each sample is controlled by the program to work independently without interfering with each other

The instrument is small in size, light in weight, and has no accessories, making it easy to carry

◆ Quick operation, especially suitable for on-site use

◆ Built in large capacity battery, can work continuously for 4 hours without external power supply

◆ Provide complete accessory configuration, using beautiful and durable aluminum alloy packaging boxes

Adopting a new instrument structure design, it is small in size and easy to carry. No mechanical moving parts, anti-interference, anti vibration, high detection accuracy, long instrument life
