The MS-57SH built on that achievement with the addition of Modbus 485 RTU and SDI-12 digital outputs for improved compatibility with data logger systems; also introducing new internal diagnostic sensors, now standard to all S-Series sensors, offering visibility over internal temperature, humidity, tilt angle; helping to ensure optimum performance without the need for regular physical checks.<\/p>\n<p>These features, along with EKO\u2019s unique 5-year recalibration interval, and new low power consumption integrated solid-state window heater make the MS-57SH the best value Class A sensors available; ideal for complex networks, hard to reach locations, and monitoring networks with restricted access.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Key Features:<\/strong><\/p>\n<p>&nbsp;<\/p>\n<ul class=\"f-list product-features-list\">\n<li>ISO 9060:2018 Class A, Spectrally Flat &amp; Fast Response<\/li>\n<li>Smart 2-channel Digital Interface (Modbus RTU | SDI-12)<\/li>\n<li>&lt;1.4W Integrated High-Efficiency window Heating for dew &amp; frost resistance<\/li>\n<li>&lt;0.2s Ultra-fast response for always accurate measurements<\/li>\n<li>Unique &lt;0.5% non-stability change of 5-years<\/li>\n<li>Level A EMI\/EMC Electronics Surge Filter &amp; Protection<\/li>\n<li>Internal Diagnostics for tilt angle, temperature and relative humidity<\/li>\n<li>5 Years Warranty &amp; Recommended Recalibration Interval<\/li>\n<li>ISO 17025 accredited calibration<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Ultra-fast and accurate, the MS-57SH is a unique digital DNI sensor fully traceable to the World Radiometric Reference with competition-beating long-term stability and exceptional reliability.
