The aromatic hydrocarbon sampler

Application

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;

10, size: 24.5 × 19 × 10 cm;

11, touch the button, easy to operate, intelligent menu, easy to operate and set.

Range of using

1. Indoor air quality; 2. Efficiency study of filters and clean rooms; 3. Pharmaceutical products; 4. Hospital environment; 5. Environmental monitoring
