Handheld Liquid Detector for Sealed Containers
This handheld detector identifies the chemical composition of a liquid still sealed in its bottle or can, covering more than 30 dangerous liquids including gasoline, kerosene, diesel, hydrochloric acid and sulfuric acid. It uses ultra-wideband pulse microwave reflection with thermal conductivity measurement, emits no radiation, and returns a result in about 8 seconds from a 200 g instrument.

Key benefits
- Identifies liquids without opening the bottle or can
- Covers more than 30 dangerous liquids including fuels and strong acids
- No radiation, harmless to the operator and the person being screened
- Result in about 8 seconds
- 200 g instrument at 216 x 50 x 79 mm
Problems it solves
- Opening containers to check them is slow, unsafe and unpopular
- A visual check cannot tell water from a clear solvent or acid
- Radiation-based methods raise objections in a public setting
- Blanket confiscation of liquids causes queues and complaints
Who it is for
- Checkpoint teams that must let drinks through but not fuels or acids
- Venues where confiscating all liquids is impractical
- Operators needing a radiation-free screening instrument
Application scenarios
- Airport, train station and subway access control
- Gymnasiums and large venues
- Important government offices
- Border seaports and customs checkpoints
Technical features
- Ultra-wideband pulse microwave reflection method
- Thermal conductivity technology
- Small size with high-speed analysis
- Straightforward single-operator use

Figures are those published by the factory for this model. Where a value is shown as TBC it is not published, and we will confirm it with the factory before you order rather than estimate it.
Compared with other models in the range
The handheld hazardous liquid detector covers 49 liquid types with a one-second result and 150,000-record storage. This instrument covers more than 30 liquids at around 8 seconds, using microwave reflection and thermal conductivity, in a 200 g body.
Use guide
- Hold the detector against the sealed bottle or can
- Wait around 8 seconds for the composition result
- Treat any identified dangerous liquid as a refusal at the checkpoint
- Explain to the person screened that the method emits no radiation
- Power from 110 to 240 V at 50/60 Hz when charging
