Relative Humidity and Temperature SD Card Logger, NIST Certified

Relative Humidity and Temperature SD Card Logger, NIST Certified

Introducing the Sper Scientific 800021C RH / Temperature SD Card Logger, a robust and versatile environmental monitoring solution designed for precision and ease of use. This advanced logger not only captures essential relative humidity (RH) and ambient temperature data but also calculates dew point and wet bulb readings. For even broader applications, it doubles as a Type K or J thermometer, making it an indispensable tool for a wide range of professionals from HVAC technicians to environmental scientists, and anyone requiring accurate climate control or material condition monitoring.

Unmatched Data Logging Capability with SD Card Convenience: Say goodbye to data storage limitations and complex software installations. The 800021C innovates by recording all data directly onto standard SD memory cards, just like a digital camera. This means virtually unlimited data storage capacity—simply swap out a full card for an empty one and continue logging. Transferring data to your computer is effortless; just insert the SD card into your computer's slot or an adapter. The data is preformatted for immediate analysis in Excel, eliminating the need for proprietary software or cumbersome cables. Need to stream data in real-time? Optional software and cables are available for direct PC connection. Every data set includes precise temperature, RH, time, and date stamps for comprehensive analysis.

Key Features for Professional Performance:

• Comprehensive Measurements: Accurately measures relative humidity (RH), ambient temperature, dew point, and wet bulb.
• Dual Thermocouple Input: Functions as a Type K or J thermometer for expanded temperature measurement capabilities.
• User-Friendly Data Handling: Records data directly to widely available SD cards for unlimited storage and easy transfer.
• Effortless Data Export: Data is preformatted for direct import into Excel, streamlining your analysis workflow.
• Real-time Data Streaming: Optional software and cables enable live data transmission to a computer.
• Essential Functions: Includes Min/Max readings, auto power-off, low battery indicator, and a data hold function for convenience.
• Designed for Clarity: Features a large, easy-to-read backlit LCD display for clear visibility in any lighting condition.
• Durable & Portable: A well-made unit with fast response times, built for reliability, and includes a fold-out tripod for stable placement.
• Ready-to-Use Kit: Comes complete in a soft carrying case with a detachable probe, 6 AA batteries, an instruction manual, and an SD card, so you can start monitoring right away.
