SMTEK is a research-based company with in-depth knowledge and experience with color-changing materials. We focus on developing products to satisfy our customers’ demands to reduce damage to people from exposure to hazardous chemicals. Our main products are chemical leak detection tape, flange band, and flange guard. In this article, we introduce ammonia leak detection tape.
1. Specification of ammonia leak detection tape
The length is uniformly 30m, and it is sold in two widths: 30mm and 50mm. If you require other specifications, please contact our company.


※ Ammonia gas (basic gas) cannot be detected by acid-alkali leak detection tape
※ Detection range is > 100ppm and response time may vary depending on flowrate and
ammonia concentration.
※ Tape discoloration may occur due to water, but interference by moisture in the air is minimized.
Recommend indoor use.
2. Performance test of ammonia leak detection tape
a) Ammonia concentration effect at 100 cc/min
Color change at different ammonia concentration @ 100cc/min

b) Flowrate effect at 100 ppm ammonia
Color change at different flowrate @ 100 ppm ammonia

c) Moisture effect

When the ammonia detection tape is exposed to the atmosphere, it is observed to change from light yellow to dark yellow due to atmospheric moisture. However, after a few days, it appears that there is almost no effect from moisture.
