The
aromatic hydrocarbon sampler has large sampling flow and good stability. The
power supply adopts AC type, convenient to use, compact size and light weight.
It is a powerful tool for sampling toxic and harmful gases in the field. It is
more suitable for the implementation of sanitary standards for air conditioning
and ventilation in public places.
Characteristics
1.
Standard flow, sampling microcomputer control DC motor mode, automatic setting
of time and flow, microcomputer control, currently widely used in China, the
flow-meter is adjusted, the accuracy and error are
relatively poor;
2,
using the way of single-chip control flow (no glass flow-meter), sampling system applied for invention
patent. High precision, stable flow and advanced technology;
3.
Automatic constant flow. Prevent the influence of voltage fluctuation on the
flow rate, and the sampling accuracy is high;
4.
ET-1 type intelligent toxic and harmful gas sampler;
5,
sampling pump constant current sampling, sampling flow 1 to 2 L / min
adjustable;
6,
standard flow control, using MCU automatic control, can be automatically set,
constant flow, to ensure that the instrument can have accurate constant flow
when the voltage changes, continuously monitor the sampling flow, so that the
sampling is more reliable;
7,
can automatically set the sampling flow and sampling time;
8.
Connect the AC/DC power converter with AC and DC power supply;
9,
sampling time can be selected from 1 minute to 99 hours;
