摘要 ARS-8500便携式余氯二氧化氯五参数快速检测仪符合《生活饮用水标准检验法》GB/T5750—2023,检测游离氯、化合氯、总氯以及二氧化氯、亚氯酸盐,广泛应用与水中消毒副产物的监测领域。

该设备是一种可快速检测余氯、总氯、化合性氯、二氧化氯及亚氯酸盐五项关键水质消毒指标的现场分析工具,广泛应用于饮用水、泳池、医疗废水等场景,确保水质安全合规。


随着公众对水质安全的关注度提升,传统实验室检测已难以满足现场即时响应的需求。便携式余氯二氧化氯五参数快速检测仪应运而生,主要用于监测水体中消毒剂(如氯、二氧化氯)的有效成分及其副产物(如亚氯酸盐),防止因消毒不足或过量带来的健康风险 。这类仪器普遍采用符合国家标准的DPD分光光度法,操作简便,检测速度快,适合环保、水务、公共设施等领域使用 。


主要检测项目与意义

余氯(Free Chlorine):衡量水中游离态氯的浓度,是判断消毒能力的关键指标,出厂水一般要求在0.3–2mg/L之间。

总氯(Total Chlorine):包含余氯和化合性氯的总量,适用于采用氯胺消毒的系统,需接触120分钟以上检测,标准值应大于0.5mg/L 。

化合性氯(Combined Chlorine):由余氯与氨氮反应生成的氯胺类物质,消毒效果弱且可能产生异味。

二氧化氯(ClO₂):高效广谱消毒剂,可减少三卤甲烷等有害副产物,出厂水限值为≤0.8mg/L 。

亚氯酸盐(Chlorite):二氧化氯消毒后的副产物,具有潜在健康风险,检出限应小于0.7mg/L 。

" PCE-PH20 easy-to-use pH meter for pH determination \/ External pH electrode \/ Recalibratable \/ Waterproof (IP 67)","The pH meter was developed to directly determine the pH in aqueous media or water based solutions. The waterproof pH tester PCE-PH20 is used for the fast and accurate measurement of pH. The practical display makes the pH value on the pH meter easy to read. Due to the waterproof and robust housing (IP 67), the pH value tester can also be used under difficult conditions. A recalibration always guarantees optimum accuracy and is very easy to perform using the optionally available calibration kits (automatic calibration function without calibration screws - to be performed only via the keyboard).Water quality in aquariums is extremely important for the living organisms that inhabit it. Slight changes in pH level and temperature may lead to aggravating results and even death of the fishes or reptiles in the water tank. Therefore, application of the appropriate pH meter is required. The ecosystem in the aquarium must be as much similar to the natural conditions as possible. So, the measurements should be regular and provide accurate result.Depending on the purpose of creating an aquarium, commercial, scientific (experimental and laboratory tests), decorative, the most desirable pH level should be maintained to provide correct living conditions for the fishes and other possible organisms there. Modern devices are often portable and easy-to-use instruments which help to monitor the changes in the pH level during the day or from day to day etc. The glass electrodes have long service life and due to a high level of precision and wide measurement range, it is possible to apply the meter often and detect the slightest deviations. For this type of measurements, the presence of the temperature sensor is very important, since the temperature change may occur within one aquarium, and it should be detected at once."
