Product overview

It applies solution absorption method to 24-hour continuously collect various harmful gases such as gas and steam state SO₂, NO_X in ambient air in constant temperature and flow. Aiming at the current problems of samplers in market, referring and learning characteristics from the similar products of foreign countries, the instrument is significantly improved in aspects of small-size and portability, constant temperature and flow rate stability, is particularly suitable for routine monitoring of gaseous substances for environmental monitoring, environment assessment, hygiene, working place, safety inspection, military, scientific research, education and other departments.

Execution standard

  HJ/T 376-2007  Technical requirement and test procedures for 24h thermostatic automatic continuous ambient air sampler

  JJG 956-2013  Air sampler

Product features
