Key Features
• Digital Hygrometer Measures Humidity with 8-Bit (0.6%RH) or 12-Bit (0.04%RH) Resolution • Operating Range: -20 to +85°C; 0 to 100%RH (see Safe Operating Range) • Automatically Wakes Up, Measures Temperature and/or Humidity and Stores Values in 8kB of Datalog Memory in 8- or 16-Bit Format • Digital Thermometer Measures Temperature with 8-Bit (0.5°C) or 11-Bit (0.0625°C) Resolution • Temperature Accuracy Better than ±0.5°C from -10°C to +65°C • Built-in Humidity Sensor for Simultaneous Temperature and Humidity Logging • Capacitive Polymer Humidity-Sensing Element • Hydrophobic Filter Protects Sensor Against Dust, Dirt, Moisture, and Contaminants • Sampling Rate from 1s up to 273hrs • Programmable Recording Start Delay After Elapsed Time or Upon a Temperature Alarm Trip Point • Programmable High and Low Trip Points for Temperature and Humidity Alarms • Quick Access to Alarmed Devices Through 1-Wire Conditional Search Function • 512 Bytes of General-Purpose Memory Plus 64 Bytes of Calibration Memory • Two-Level Password Protection of All Memory and Configuration Registers • Communicates to Host with a Single Digital Signal at Up to 15.4kbps at Standard Speed or Up to 125kbps in Overdrive Mode Using 1-Wire Protocol • Individually Calibrated in a NIST-Traceable Chamber • Calibration Coefficients for Temperature and Humidity Factory Programmed into Nonvolatile (NV) Memory Key Features
• Digital Identification and Information by Momentary Contact. • Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code + 48-Bit Serial Number + 8-Bit CRC Tester) - Assures Absolute Traceability Because no Two Parts are alike. • Multidrop Controller for 1-Wire Net. • Chip-Based Data Carrier Compactly Stores Information. • Data Can be Accessed While Affixed to Object. • Button Shape is Self-Aligning with Cup-Shaped Probes. • Durable Stainless Steel Case Engraved with Registration Number Withstands Harsh Environments. • Easily Affixed with Self-Stick Adhesive Backing, Latched by its Flange, or Locked with a Ring Pressed Onto its Rim. • Presence Detector Acknowledges When Reader First Applies Voltage. • Meets UL#913 (4th Edit.). Intrinsically Safe Apparatus: Approved Under Entity Concept for Use in Class I, Division 1, Group A, B, C and D Locations (application pending).
