CMH-20 is a precision microprocessor-based meter using a chilled mirror to measure the absolute humidity of gases. The measurement is\u00a0based on the definition of the dew point. CMH-20 has user-friendly interface and a large clear graphic display.
\nInside the measuring head is a gold plated copper mirror chilled by a two-stage Peltier, precision resistor Pt100 measuring the temperature on\u00a0the surface of the mirror and an optical detection system.\u00a0Condensation of dew on the surface of the mirror is indicated by an the optical system.<\/p>\n","protected":false},"featured_media":4124,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[172,168,165],"class_list":{"0":"post-5342","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-control-and-measuring-devices","7":"product_cat-dewpoint-hygrometers-and-transmitters","8":"product_cat-loggers","10":"first","11":"outofstock","12":"taxable","13":"shipping-taxable","14":"purchasable","15":"product-type-variable"},"acf":[],"yoast_head":"\nDewpoint hygrometer with chilled mirror type CMH-20 - Czaki Thermo Product<\/title>\n<meta name=\"description\" content=\"More information about Dewpoint hygrometer with chilled mirror type CMH-20 at czaki.pl website.
