Handheld Comprehensive Toxicity Detector

I. Product Overview

The handheld biotoxicity tester is a new-generation acute biological toxicity analyser for laboratory use. It is a toxicity testing system based on bioluminescence sensing technology that performs rapid qualitative testing from the change in light output of luminescent bacteria during metabolism. Compared with traditional test organisms such as fish and daphnia, the luminescent bacteria method is simple, fast, sensitive, highly adaptable, reproducible, accurate, low-cost and widely applicable. It is designed for environmental pollution assessment, emergency incidents, safety screening and routine testing, and can determine the overall toxicity of heavy metals, poisons, nerve agents and pesticide formulations in water. It complies with the national standard GB/T 15441-1995 and the international standard ISO 11348-3.

II. Applications

Drinking water testing; emergency response to biological contamination; emergency response to toxic chemicals; toxic and hazardous waste; municipal drainage; rainwater testing; drilling fluid and mud testing; mining; wastewater; soil and water body testing; industrial wastewater discharge testing; process water testing; seawater testing; medical and pharmaceutical product testing; food packaging testing; personal care and household chemical testing; sediment testing; rainwater runoff testing; solid sample testing; and food processing water testing.

III. Measuring Principle

The handheld biotoxicity tester performs three functions: toxicity testing, ATP testing and determination of microbial contamination. Toxicity testing uses naturally occurring luminescent bacteria, which emit light during normal metabolism. When placed in a toxic environment their cellular respiration is affected and light output decreases. The light detector measures the light output before and after exposure to the toxic environment, and the degree of decrease corresponds to the level of toxicity.

IV. Key Features

1. Complies with the national standard (GB/T 15441-1995) and the international standard (ISO 11348-3).

2. A biological early warning system sensitive to more than 3,000 toxic compounds.

3. Fast, reliable and reproducible results: within 15 minutes of sample preparation.

4. A simple, fast and highly sensitive portable water quality tester designed specifically for screening acute toxicity and adenosine triphosphate (ATP).

5. Android smart operating system — more intelligent and more user-friendly.

6. Combines an ATP testing function that quantifies ATP concentration on site, strengthening the interference resistance of the toxicity tester and providing multiple functions in one instrument.

7. Portable handheld design for convenient on-site testing.

8. The detection sleeve uses a plug-in design for flexible use and periodic cleaning, extending the service life of the instrument.

9. 3.5-inch true-colour touch screen, removing cumbersome keys and making operation more convenient.
