Iodine deficiency persists as the leading cause of preventable brain damage and reduced intellectual capacity in the world. The most effective method for the elimination of iodine deficiency is the consumption of adequately iodized salt. Ensuring that a population receives adequately iodized salt demands careful monitoring of the salt iodine content. We evaluated the WYD Iodine Checker, a hand-held instrument that quantitatively measures the salt iodine content on the basis of a colorimetric method, and compared its performance with iodometric titration. Performance testing results indicated that the WYD Iodine Checker is a highly precise, accurate, and sensitive tool for measuring salt iodine content. It is a user-friendly instrument that is based on a simple methodology and a straightforward salt sample preparation and testing procedure. We recommend further testing to examine the field performance of the WYD Iodine Checker when measuring iodate salt samples.
碘缺乏仍然是全球可预防脑损伤和智力下降的主要原因。消除碘缺乏的最有效方法是食用加碘量充足的盐。确保人群食用加碘量充足的盐需要仔细监测盐中的碘含量。我们评估了WYD碘含量检测仪，这是一种基于比色法对盐碘含量进行定量测量的手持式仪器，并将其性能与碘量滴定法进行了比较。性能测试结果表明，WYD碘含量检测仪是一种用于测量盐碘含量的高精度、准确且灵敏的工具。它是一种用户友好型仪器，基于简单的方法以及直接的盐样品制备和测试程序。我们建议进一步测试，以检验WYD碘含量检测仪在测量碘酸盐盐样品时的现场性能。
