Working Environment Measuring Instruments
|
Air flow indicator |
|
* AS-1
|
|
| |
|
Flow visualization is common for air flow check in room and function check of local exhaust ventilation, but heat source is not suitable.
The Model AS-1 is designed to check velocity and direction of air flow with a smoke tube (No.301) which reacts with vapour in the air and generates white smoke.
|
|
* Composition
|
| |
| |
- Rubber bulb
- Soft case * Smoke tube (No.301) is not included.
|
|
Air flow indicator (for continuous smoke generation)
|
|
* AS-2
|
| |
|
Flow visualization is common for air flow check in room and function check of local exhaust ventilation, but heat source is not suitable.
The Model AS-2 is designed to check velocity and direction of air flow continuously with a smoke tube (No.301) which reacts with vapour in the air and generates white smoke.

|
Have you ever experienced you were uncomfortable when you had to check air flow with a smoke tube where ventilation fan or hood was unreachable or was located at confined space?
With a switching operation on the pump, air flow check continuously or intermittently up to 2 metres is possible.

* Charcoal tube (800B)
|
|
800B is designed for sampling and measurement of organic solvents in air with personal sampler for industrial hygiene (conformed to NIOSH requirements).
Sample air containing vapour of organic solvents is passed through a glass tube packed with charcoal which adsorbs the solvent. Adsorbed solvent is recovered with desorption solvent leeching followed by gaschromatographic analysis.
Useful for sampling organic solvent vapours.
|
|
801 is designed for sampling organic solvents in environmental air, particularly for polar solvents such as Methanol and Acetone which cannot be sufficiently adsorbed onto charcoal.
Organic solvent vapour is adsorbed onto the silica gel while passing through the tube. Adsorbed solvent is recovered with a desorption solvent followed by gaschromatographic analysis.
When sample air corresponding to 60 to 80 & of the amount causing breakthrough is passed, the colour begins to change from blue to pink by the moisture from the silica gel side predicting breakthrough.
