The first kind of detector which is approved by Standardization Administration of China can be designed individually according to users’ need among food safety detection industry.

It can stand by for 5 days in a power saving mode.

Support dynamics method detection.

1. Principle

This detector is developed basing on enzyme reaction. If there is organophosphorus or carbamate in the test sample, they will inhibit the activity of cholinesterase to affect the reaction speed of coloration. This detector can detect the quantitative result of pesticide residue by measuring the variation rate of absorbance. 

2. Application

This detector can accurately and rapidly detect pesticide residue of organophosphorus and carbamate in vegetables, fruits, tea, grains, water and soil. It is one of basic equipment to ensure the implementation of market admittance system for food safety.

It is suitable for agricultural system, food and drug system, quality supervision system, epidemic prevention, vegetable production bases, wholesales vegetable markets and supermarkets.

3. Characteristic

3.1  High efficiency

6~18 channels, easy operation, rapid detection, it can detect 6~18 samples at the same time.

3.2  High flexibility

There are two detecting modes, starting multichannel at the same time or starting single channel separately. When detecting multiple samples, users can select the detecting modes according to operating proficiency.

3.3  Long standby time

Built-in large capacity rechargeable battery can stand by for 5 days, it is suitable for detection on spot in the field.

3.4  Large storage capacity

48,000 groups of detecting data can be stored automatically.

The testing results can be printed manually or automatically. The history testing data and criterion also can be printed optionally.

3.5  Powerful network monitoring and data processing

With the interfaces of RS-232, USB and wireless data transmission, it is available for different connection modes.
