Simply take it out of the bag and place it to easily measure low concentrations of acidic and alkaline gases!
The "Passive Indicator" is an indicator that detects low concentrations of harmful substances that can affect cultural properties. It mainly consists of a detection agent, a removal agent, and the main body (outer shell), and there are two types of products: organic acids and ammonia. The detection agent is a dried substance that has been impregnated with a reagent that reacts with the substance to be detected, resulting in a color change. The removal agent is something that is removed beforehand to prevent interference with the reaction between the substance to be detected and the detection agent. 【Features】 ■ No power supply is required; measurement can be done simply by placing it. ■ Small (24mm in diameter, 8mm thick), can be installed in narrow spaces, and discoloration can be easily confirmed visually. ■ Reacts only to organic acids and ammonia gas without being affected even when multiple types of gases coexist. *For more details, please download the PDF or feel free to contact us.
