Instrument features:

1Instrument composition: consisting of a host, sampling device, and reagent kit, suitable for on-site and laboratory use.

2Optical path system: The instrument light source and detector adopt an all solid state structure, with no movable parts, and high accuracy and precision; Adopting energy-saving design with automatic light source switchingThe service life of the light source is over 100000 hours. Compared with traditional spectroscopic systems, it has a simple structure and strong seismic and moisture resistance.

3Built 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.

4Measurement method: equipped with dedicatedA 19mm color comparison bottle with engraved lines can be used as both a reaction bottle and a measurement bottle without the need for transfer, greatly facilitating customer use and reducing operational errors.

5Specialized reagent kit: Equipped with a specialized reagent kit, greatly reducing the preparation time of reagents, easy to operate, and convenient to use.

6Power supply method: AdoptingPowered by a 9V battery and equipped with a power-saving module, it automatically shuts down in 30 minutes without any operation; The instrument has a self diagnostic function for battery level, automatically indicating insufficient battery.

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

8Sampling method: Pump suction sampling, sampler quantitatively collects air volume, with flow correction function.
