Instrument features:

1. Testing method: The methanol testing method complies with the "GB/T5009.48 Analysis Method for Hygienic Standards of Distilled Liquor and Blended Liquor"

2. Instrument composition: consisting of a host, sample pretreatment equipment, and reagent kit, suitable for on-site and laboratory use

3. Optical path system: The light source and detector adopt an all solid state structure, with high accuracy and precision; Adopting energy-saving design with automatic light source switch, the service life of the light source is over 100000 hours.

4. Built in curve: The instrument has a built-in working curve, which does not require the preparation of standard solutions. After zero point calibration with matching reagents, rapid quantitative determination of samples can be achieved.

5. Measurement method: The sample color development and measurement are carried out in the same sealed container (cylindrical), without the need for transfer, which improves the detection precision.

6. Power supply method: Powered by a 9V battery, it has self diagnosis of battery level and energy-saving function, automatically indicating low battery level. The instrument will automatically shut down after 30 minutes of inactivity.

7. Consumables and accessories: Provide complete specialized pre-treatment equipment and consumables, one-stop service.

8. Special reagent kit: equipped with specialized pre made reagents, shortening the preparation time of reagents, easy to operate, and convenient to use.
