Applicable scope:

This instrument utilizes chemical solutions to absorb the hazardous gases and samples the various hazardous gases in the environmental atmosphere, at the labor and operational places, within the rooms, and on public occasions; it may be applied by the entities such as environment protection, labor health, safety monitoring, and military authorities and the institutes of scientific researches for regular gas monitoring.

Major features:

1.    An imported thin-membrane pump is used as a sampling pump to secure stable sampling flows and guarantee 24-hour continuous sampling;

2.    The semiconductor refrigerating and heating elements, double-loop temperature measurements, double-loop semiconductor refrigeration or heating etc have been employed at the earliest time to keep the solution that absorbs hazardous gases constantly at the set temperature;

3.    This instrument is designed with the advanced embedded software and hardware systems, simplified and convenient human-instrument interfaces, and a high degree of intelligence;

4.    This instrument is installed with a real-time clock which enables setting of the time for sampling commencements, sampling durations, and sampling intervals;

5.    This instrument is capable to automatically measure the pressure and temperature of the environmental atmosphere;

6.    This instrument is inbuilt with rechargeable batteries, stores the sampled data, and is functional to be automatically actuated when its power supply is resumed;

7.    It is optional to select a double-loop rotor flowmeter atmosphere sampling system;

8.    User password protections;

9.    It is optional to select a printer for data printing, or communications with a computer;

10.   This instrument is small in size, light in weight and convenient for sampling in the wild.
