GDY-301S Indoor Air On site Ammonia Concentration Tester

The principle of the portable on-site ammonia analyzer is based on the colorimetric analysis method established by the selective absorption of visible light by yellow compounds generated by the reaction of ammonia and chromogenic reagents in the tested sample. The instrument consists of a silicon light source, a colorimetric bottle, an integrated photoelectric sensor, and a microprocessor, which can directly display the ammonia content in the tested sample on the LCD screen.
Instrument features:
1. By using national standard methods (GB/T18204, 25-2000), the ammonia concentration can be directly displayed.
2. Can quantitatively measure ammonia in gas samples on site.
3. Chemical reagent packaging for color development requires minimal sample and reagent usage, which can reduce and prevent secondary contamination.
4. Pulse mode power supply, low power consumption, one 9V battery can be used for more than 40 hours, and automatically shuts off after 10 minutes of stopping input commands.
5. The host has a small size (140 × 70 × 30mm), light weight (the whole machine weighs 180g, including the battery), simple operation, and easy portability.
