Model 200 is appropriate for high concentrations and offers single particle counting up to 2,000,000 particles\/cm<sup>3<\/sup>. It can be used for ambient air monitoring without a dilution system.<\/p>\n<p>The ENVI-CPC 200 can be equipped with an isothermal Nafion<sup>\u00ae<\/sup>\u00a0aerosol dryer that has no consumables and can be used for months without maintenance. The humidity of the aerosol at the inlet is measured and controlled. Additionally, it has a second pump for the working fluid in order to suck it out of a large butanol reservoir. Due to those features it can operate for months without refilling the fluid reservoir.<\/p>\n<p>The cut-off diameter is, as requested for ambient air monitoring CPCs, at 7 nm. Another advantage is the high aerosol flow rate of 1 l\/min which reduces diffusion losses to a minimum. The ENVI-CPC 200 can be equipped with a powerful meteorological sensor that monitors ambient air temperature, pressure, humidity, wind speed, wind direction and precipitation type and intensity. A protective outdoor housing is available.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-medium wp-image-4111\" src=\"https:\/\/palas-china.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10-300x166.png\" alt=\"\" width=\"300\" height=\"166\" srcset=\"https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10-300x166.png 300w, https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10-1024x565.png 1024w, https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10-768x424.png 768w, https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10-600x331.png 600w, https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2020\/07\/1-10.png 1200w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Fig. 1: Counting efficiency curve of the ENVI-CPC measured at the Leibniz Institute for Tropospheric Research<\/p>\n<p>The control of the volume flow is enabled by an internal flow sensor with accessed long-life membrane pump. Contrary to a control with critical nozzle a contamination of the system does not lead to an drop of the volume flow. This is important especially for long-time measurements in ambient air. Additionally, the volume flow can be calibrated afterwards by the user.<\/p>\n<p>As user interface the ENVI-CPC 200 has a 7\u201c touch display. For remote and network applications the ENVI-CPC 200 supports a standardised interface with different protocol choices, e.g. Modbus, Bayern-Hessen protocol and features like remote access and data storage in the internet or in an internal network.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nanoparticle counter for ambient air monitoring with Nafion<sup>\u00ae<\/sup>\u00a0aerosol dryer (optional) and high volume flow for up to 2 \u2022 10<sup>6<\/sup>\u00a0particles\/cm<sup>3<\/sup>\u00a0(single count mode)<\/p>\n","protected":false},"featured_media":4197,"template":"","meta":[],"_links":{"self":[{"href":"https:\/\/palas.com.cn\/en\/wp-json\/wp\/v2\/product\/4110"}],"collection":[{"href":"https:\/\/palas.com.cn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/palas.com.cn\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/palas.com.cn\/en\/wp-json\/wp\/v2\/media\/4197"}],"wp:attachment":[{"href":"https:\/\/palas.com.cn\/en\/wp-json\/wp\/v2\/media?parent=4110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
