Complete with a precision sensor for \u00b10.2\u00b0C accuracy, this logger measures temperatures between -40\u00b0C and 70\u00b0C (-40\u00b0F to 158\u00b0F) in air and up to 50\u00b0C (122\u00b0F) in water. The waterproof, streamlined case allows for extended deployment in freshwater or saltwater. And the optical USB interface lets you offload data even while the logger is wet or under water. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (either the assembly-required RS1 Solar Radiation Shield or the pre-assembled M-RSA Solar Radiation Shield).<\/p><p>&nbsp;<\/p>","applications":["Environmental Research & Protection","Ecology","Water Resource Management","Aquatic Ecology","Water Quality & Compliance","Hydrology & Groundwater Monitoring","Watershed Management","Wetland & Stormwater","Dam Management"],"brand":"HOBO","communication":"Optic\/USB","compatibility_callout":["HOBOware"],"compatible_items":{"Accessory":{"Compliance_Certificates":{"items":["COMPLIANCE CERT"]},"Data_Offload_Base_Stations_Shuttles_Couplers":{"items":["COUPLER2-C"]},"NIST_Setup_Certifications":{"items":["NIST-SETUP","NIST-TEMP-POINT"]},"Protective_Covers_and_Boots":{"items":["85-CAPLUG-H20-B","BOOT-BLK","U22-U24-CAP"]},"Solar_Radiation_Shields":{"items":["M-RSA","RS1"]},"Accessories":{"items":["ME-BP"]}},"Required Communications":{"Data_Offload_Base_Stations_Shuttles_Couplers":{"items":["BASE-U-4","U-DTW-1"]}},"Required Software":{"Graphing_Analysis":{"items":["BHW-PRO-DLD","BHW-PRO-USB"]}}},"country":"US","customers_also_bought":["MX2001","U-DTW-1","U20L-0x","U24-002-C"],"field_documents":[{"nid":9491},{"nid":10271}],"environment":["Outdoor","Water"],"important_information":"Requires HOBOware software and either an Optic USB Base Station or HOBO Waterproof Shuttle (U-DTW-1).
