| 1EL |
Carbon monoxide, CO
25-400 ppm
(10 tubes/box) |
The air in a class room is investigated using combustion apparatus. (Carbon monoxide will be produced due to imperfect combustion). The environmental influence of CO contained in the exhaust fumes of an automobile can also be investigated. |
CH100128 |
£12.50 |
| 2EL |
Carbon dioxide, CO2
0.03-1.0%
(10 tubes/box) |
The air in a class room is investigated using combustion apparatus, and/or the difference between sources of fresh air and stale air. Changes in the concentration of CO2 caused by photosynthesis of plants is investigated. |
CH100136 |
£12.50 |
| 2EH |
Carbon dioxide, CO2
0.5-8.0%
(10 tubes/box) |
Changes in the concentration of CO2 in the air caused by the respiration of humans and animals, and the photosynthesis of plants, are investigated. Changes in the concentration of CO2 in the air caused by the combustion of organic substances (chemical reactions) are investigated. |
CH100144 |
£12.50 |
| 3EL |
Ammonia, NH3
2.5-60 ppm
(10 tubes/box) |
NH3, one of the causes of foul smells generated in an animal-breeding house or a communal lavatory, is investigated. NH3 produced in a production experiment is confirmed. Changes in NH3 by a chemical reaction are investigated. |
CH100152 |
£12.50 |
| 4EL |
Hydrogen sulphide, H2S
10-120 ppm
(10 tubes/box) |
H2S, one of the causes of foul smells generated in an animal-breeding house, a communal lavatory, a hot-spring resort or a volcanic zone, etc., is investigated. A chemical reaction in which SO2 is produced by combustion of sulphur containing coal and crude oil is investigated. |
CH100160 |
£12.50 |
| 5EC |
Sulphur dioxide, SO2
2-40 ppm
(10 tubes/box) |
A chemical reaction in which SO2 is produced by combustion of sulphur containing coal and crude oil is investigated. |
CH100168 |
£12.50 |
| 8EL |
Chlorine, Cl2
1-16 ppm
(10 tubes/box) |
Cl2 in a collecting experiment is investigated. Changes in Cl2 by a chemical reaction are investigated. |
CH100176 |
£12.50 |
| 11EL |
Nitrogen oxides, NOX
1-20 ppm
(10 tubes/box) |
Contamination in a class room where combustion apparatus is in use is investigated. The environmental influence of NOX in the exhaust fumes of an automobile is investigated. |
CH100184 |
£12.50 |
| 18EL |
Ozone, O3
0.5-10 ppm
(10 tubes/box) |
O3 produced in an ozonator or a sterilizer is investigated. |
CH100192 |
£12.50 |
| 31E |
Oxygen, O2
6-24 %
*(5 tubes/box) |
Changes in the concentration of oxygen caused by human respiration, animal respiration and the photosynthesis of plants are investigated. Change in oxygen by combustion (chemical reaction) can also be investigated. |
CH100200 |
£13.50 |
