Abstract

A portable colorimeter using a red-green-blue light-emitting diode as a light source has been developed. An embedded controller sequentially turns emitters on and off, and acquires the signals detected by two photo diodes synchronized with their blinking. The controller calculates the absorbance and displays it on a liquid-crystal display. The whole system, including a 006P dry cell, is contained in a 100 x 70 x 50 mm aluminum case and its mass is 280 g. This colorimeter was successfully applied to the on-site determination of nitrite and iron in river-water.

摘要

一种以红绿蓝发光二极管作为光源的便携式色度计已被研制出来。一个嵌入式控制器依次打开和关闭发射器，并采集与它们的闪烁同步的两个光电二极管检测到的信号。该控制器计算吸光度并将其显示在液晶显示屏上。整个系统，包括一个006P干电池，被封装在一个100×70×50毫米的铝制外壳中，其质量为280克。这种色度计已成功应用于河水中亚硝酸盐和铁的现场测定。
