TMP-1500air sampler
TPM-1500The electronic time controlled atmospheric sampler is a commonly used instrument for collecting various harmful gases. It is widely used in atmospheric environment monitoring, health and epidemic prevention, labor protection, scientific research, teaching and other units, and can also be used in conjunction with relevant instruments. By analyzing the sampled gases, we can understand the degree of environmental damage caused by harmful gases and provide the actual situation of pollution to relevant regulatory authorities for taking countermeasures to ensure a healthy living environment for people.
This instrument has a compact structure, stable performance, small size, light weight, and is easy to carry. It is currently an ideal instrument among small portable atmospheric sampling instruments in China. By switching different sampling loads and using different absorption methods, the sampling instrument can be used for multiple purposes.
1 Introduction to the Structure of Atmospheric Sampler
The whole machine of the instrument consists of a diaphragm pump, a regulating valve, a buffer, a flow meter, an electronic timing control circuit, an undervoltage indicator circuit, and a power supply.
1Diaphragm pump for atmospheric sampler Its structure and assembly adopt technology, making small pumps have the advantages of compact structure, high efficiency, high pumping pressure, strong load capacity, stable flow rate, low power consumption, and low noise. In100 mmHgUnder load capacity, it can obtain1L/min左右。
2Time control structure of atmospheric sampler This machine adopts a fixed type8The timing structure does not need to be set before sampling every time, nor does it fail to insert due to setting errors.
