GDYS-103SE鎂測定儀是一款適用于多種水質(zhì)中鎂含量快速測定的儀器，廣泛應(yīng)用于生活飲用水及其水源水、地表水和地下水等水質(zhì)檢測。其檢測方法采用酸性格蘭K法，具有較高的準(zhǔn)確性。

該儀器由主機、樣品前處理裝置和試劑包等構(gòu)成，整箱包裝，體積小、重量輕，操作簡單，既適合野外現(xiàn)場使用，也適合實驗室操作。其光路系統(tǒng)采用固體發(fā)光器件，光源/單色器、比色槽、傳感器一體化，無可動部件，脈沖供電方式使光源使用壽命可達(dá)10萬小時，增強了儀器的抗震、抗潮性能，提高了精度、靈敏度和可靠性。

儀器內(nèi)置工作曲線，無需配置標(biāo)準(zhǔn)溶液，只需用配套試劑進行零點校正后，即可實現(xiàn)樣品的快速定量測定。樣品顯色和測量在同一密閉器皿中完成，無需轉(zhuǎn)移，進一步提高了檢測精度。此外，該儀器采用9V電池供電，滿足實驗室測定需要的同時，也支持現(xiàn)場測定，且具有電量自診斷和節(jié)能功能，自動提示電量不足，30分鐘無操作自動關(guān)機。

The GDYS-103SE Magnesium Determination Instrument is a device for the rapid determination of magnesium content in various types of water, including drinking water and its source water, surface water, and groundwater. It employs the Acid Chrome K method for detection, ensuring high accuracy.

The instrument consists of a host unit, sample pretreatment device, and reagent pack, all packaged together. Its compact size and light weight make it easy to operate both in the field and in the laboratory. The optical system uses a solid-state light-emitting device that integrates the light source, monochromator, cuvette, and sensor. With no moving parts and a pulse power supply, the light source has a lifespan of up to 100,000 hours. This design enhances the instrument s resistance to vibration and moisture, improving its precision, sensitivity, and reliability.

The GDYS-103SE features an internal calibration curve, eliminating the need for standard solution preparation. After zero-point calibration with the accompanying reagents, it can quickly determine the magnesium content in samples. The sample coloring and measurement are performed in the same closed vessel, avoiding transfer and further increasing detection accuracy. Additionally, the instrument is powered by a 9V battery, suitable for both laboratory and on-site measurements. It also has a self-diagnostic power function and energy-saving features. It automatically alerts when the power is low and shuts down after 30 minutes of inactivity.
