Product description:

■DDY-1.5B Smart series type (individual, air, gases, poisons, and low flow) air sampler, in strict accordance with the national standards for occupational health and workplace air monitoring and HBC 2-2001Of the ambient air samplersJJG 956-2000Standards and the development and production of the air sampler, used to collect the sulphur dioxide in the atmosphere and the shop floor, carbon monoxide, NOx and other harmful gases special instruments. Has a novel design, advanced technology, small size, high accuracy, compatibility, it is widely used in indoor and outdoor air monitoring, disease prevention, safety, military, weather, research and teaching, metallurgy, petrochemicals, railways, building materials and other fields of health monitoring and evaluation, can also be used with the relevant instruments.

The apparatus imported single-chip microcomputer LCD Digital liquid crystal display system, compact structure, stable performance, accurate, highly integrated, high precision, high compatibility, low error, and other advantages, is the small portable domestic atmosphere (individual, air, gases, poisons, and low flow) sampled instruments an ideal instrument. Replacing different sample loading, which can collect toxic gases, also available with activated charcoal sampling tubes, silicone sampling tubes, gas and a variety of supporting the use of solid sorbent tubes, with ф25mm Micro-sampling head impact catcher to collect air in the hazardous dust and respirable dust (RSP) .

A, function and characteristic:
