RT-AP4 four-channel ambient air particulate matter sampler

North Korea RT-AP4 four-channel ambient air particulate matter sampler

RT-AP4 four-channel ambient air particulate matter sampler adopts homologous secondary cutting technology to realize simultaneous sampling of various particulate matter four-filter membranes. The four sampling filter membranes can be any one or more combinations of TSP, PM10, PM5, PM2.5 and PM1. At the same time, four suction pumps and four flow sensors are used to realize flow sharing control. The sampler has the characteristics of reliable operation, simple operation, and simultaneous collection of multi-component four filter membranes, which is an ideal choice for source analysis sampling.

RT-YLA membrane low temperature transport box

North Korea RT-YLA membrane low temperature transport box

The filter membrane cryogenic transport box has the characteristics of small size, light weight, easy to carry, air transportation, real-time recording of transportation temperature and trajectory, and is an ideal choice for long-distance transportation of particulate sampling filter membranes. He adopts ultra-high cold preservation and blocking membrane inner container design, secondary low temperature storage technology, long-term refrigerant technology and ultra-light packing box technology, which can realize long-term storage at low temperature below 4 ℃ without external power supply. The temperature recording instrument can record the temperature data in real time and transmit the data to the cloud server. Combined with the handheld terminal, it can easily query the transportation track and temperature curve of the sample.
