Built with a precision-molded ABS housing and leak-proof ultrasonic welding, it utilizes an inclined column design to physically magnify minute pressure variations. Filled with specialized low-volatility red gage oil (specific gravity 0.826), it delivers clear, continuous, and explosion-proof readings without requiring electrical power or frequent fluid refills.<\/p>\n<p>Ideal for HVAC filter monitoring, cleanroom pressure tracking, and duct airflow velocity measurement, the EM700 operates reliably across -10\u00b0C to 60\u00b0C. It features an integrated overpressure safety reservoir to prevent fluid loss during pressure surges, along with a zero-adjustment knob and built-in leveling bubble for effortless installation and precise calibration.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p data-path-to-node=\"0,0,0\"><b data-path-to-node=\"0,0,0\" data-index-in-node=\"0\">Inclined Column Design<\/b>: Physical magnification enables high sensitivity and precise micro-differential pressure readings without power supply.<\/p>\n<p data-path-to-node=\"0,1,0\"><b data-path-to-node=\"0,1,0\" data-index-in-node=\"0\">Ultrasonic Seal<\/b>: Precision ABS construction with ultrasonic welding prevents oil leakage for long-lasting durability.<\/p>\n<p data-path-to-node=\"0,2,0\"><b data-path-to-node=\"0,2,0\" data-index-in-node=\"0\">Low-Volatility Red Oil<\/b>: Specially formulated 0.826 specific gravity red oil provides high visibility and low evaporation.<\/p>\n<p data-path-to-node=\"0,3,0\"><b data-path-to-node=\"0,3,0\" data-index-in-node=\"0\">Overpressure Protection &amp; Easy Zeroing<\/b>: Built-in overflow safety reservoir, integrated leveling bubble, and zero-adjustment knob ensure simple setup and safe operation.<\/p>","protected":false},"featured_media":4128,"template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[4,75,93],"product_tag":[],"class_list":["post-4126","product","type-product","status-publish","has-post-thumbnail","product_cat-pressure","product_cat-mechanical-differential-pressure-gauge","product_cat-em700-series","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/product\/4126","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/media\/4128"}],"wp:attachment":[{"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/media?parent=4126"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/product_brand?post=4126"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/product_cat?post=4126"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.elecall.com\/es\/wp-json\/wp\/v2\/product_tag?post=4126"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
