The MFR 012 electromechanical hygrostat is designed to control
\nthe relative humidity inside enclosures. When connected to
\nan enclosure heater (dehumidifier), it will energize the heater at
\nthe humidity set point in order to raise the dew point. This helps
\nprevent damage and malfunction of electronic components
\ncaused by condensation
\nand corrosion.\u00b9 The MFR 012 can also be used to control cooling
\nfans, warning lights or other devices.
\n\u00b9 The critical relative humidity level for most components is 65%.
\nAbove 65% RH, condensation can form and cause malfunctions
\nof electronic equipment. Long term, this can lead to corrosion
\nand permanent damage of electronic components and systems.<\/p>","protected":false},"featured_media":344581,"template":"","meta":{"_acf_changed":false,"rs_blank_template":"","rs_page_bg_color":"","slide_template_v7":""},"product_brand":[],"product_cat":[4168],"product_tag":[],"class_list":["post-339946","product","type-product","status-publish","has-post-thumbnail","product_cat-environmental-controls","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
