Food sulfur dioxide rapid analyzer

GDYQ-801SCFood sulfur dioxide rapid analyzer
Food sulfur dioxide rapid analyzerApplication fields:

Suitable for rapid quantitative determination of sulfur dioxide in sugars, alcoholic beverages, and various dried fruits.

Instrument features:

● Detection method:The colorimetric method complies with GB/T5009.34-2003 Determination of Sulfites in Foods, and the sample pretreatment adopts rapid coarse sieving method.

● Instrument composition:The detector consists of a host, pre-processing device, reagent kit, etc., packaged in a whole box. The instrument is small in size, light in weight, easy to operate, and suitable for field and laboratory use.

● Optical path system:Solid state light-emitting devices are used as both light sources and monochromators. The light source/monochromator, colorimetric tank, and sensor are integrated, with no movable parts and pulse power supply. The light source has a service life of 100000 hours. Compared with traditional spectroscopic systems, the optical system structure is simple, enhancing the instrument's seismic and moisture resistance performance, greatly improving the accuracy, sensitivity, and reliability of the instrument.

● Display mode:Adopting a 4.7-inch large LCD display screen with Chinese language display. Directly display the concentration of the measured substance and show the absorbance of the current measurement.

● 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.

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 accuracy.

● Special reagent kit:By using specialized pre made reagents, the preparation time of reagents is greatly shortened, the operation is simple, and the use is convenient. After adding the specialized reagent kit for color development, only zero point calibration is required to achieve the determination of the analyte.

● Single machine software:The instrument has multiple functions such as measurement, setting, recording, saving, and data statistical processing.

Online software:It can input information such as sample name, tested item, testing institution, and testing personnel, and export data in EXCEL format. Test reports can be directly written and printed through an external printing system.

● Data interface:External USB interface, supporting data management and instrument control.

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