The increasing general awareness of atmospheric air pollution and t serious impacts of pollutants and hazards to the health and well-being of industrial workers has resulted in greater stress on accurate, reliable and frequent assessment of work space pollution and workerexposure. The data so generated are needed for corrective measures to safe guard the workers as per Factory act !948 and amendment in 1986-87.

Ecotech IAS 019 Handy Sampler uses a small worlds best imported light weight battery operated pump to draw air through 37 mm dia filter and through suitable absorption solution contained in two impinger fitted in series. Thus besides particulates any two gaseous pollutants can be monitored simultaneously.

IAS 019 sampler uses wet chemicals method to sample gaseous toxicants the same hardware can be used to sample a variety of pollutants including Oxides of Sulphur and Nitrogen, Halogens, Ammonia, Sulphides ozone etc. The Particulate sampling head provided with the system would be useful for monitoring particulates like silica cement dust metal fumes, asbestos fiber etc. in work area of cement plants, foundries mines and also in indoor air quality monitoring etc.

To ensure complete absorption and reduce loss of absorbing solutions by evaporation the impinger tubes of IAS 019 sampler are kept in an insulated ice-tray.

Rechargeable batteries have been used with sufficient storage to operate the system for 8 hours making it easier to compare workers dose to the TLV levels specified.

A separate charger is provided with IAS 019 to recharge the batteries overnight. A digital timer has been incorporated in the IAS 019 to facilitate unattended operation.
