GS-3C Atmospheric SamplerDetailed product description：

The GS-III C atmospheric sampler (hereinafter referred to as the instrument) is designed to meet the requirements of users for small individualization and single gas path sampling. This instrument adopts single gas path sampling and is used for short-term collection of harmful gases such as TVOC, SO2, NOX, Hg2, CL2, S2H in the air by environmental protection personnel in engineering quality indoor testing, environmental monitoring stations, disease control centers, scientific research units, colleges and universities, and industrial and mining enterprises.

The GS-3C atmospheric sampler has a low voltage alarm function: it uses six 5 # high-capacity nickel hydrogen batteries inside, which can be used continuously for about 6 hours when fully charged. When the battery is low, the instrument will emit a buzzing sound and digital flashing phenomenon.
Timed sampling: The timed time is controlled by a microcontroller and can be set arbitrarily within 1 minute to 99 hours and 59 minutes.
Pre alarm function: When there are 30 seconds left before the end of sampling, the buzzer will sound an alarm in advance, and the end of sampling will also sound an alarm.
This instrument has the characteristics of small size, light weight, and easy portability
