More About This Item

This environmental monitoring instrument records data directly to a standard SD memory card instead of relying on fixed internal memory. When storage capacity is reached, simply replace the card to continue monitoring, providing virtually unlimited long-term data collection capabilities.

Recorded data is easily transferred to a computer using the included USB memory card reader. Generated text reports include time-stamped measurement records and can be imported directly into spreadsheets, databases, and reporting systems for convenient documentation and analysis.

The unique four-line display simultaneously presents ambient temperature, relative humidity, calculated dew point, and current time. Programmable alarm limits can be established for temperature, humidity, and dew point measurements. Whenever a parameter exceeds the selected limits, both audible and visual alarms immediately notify users.

User-configurable settings include date, time, sampling interval, temperature units, alarm thresholds, and automatic power-off operation. Multiple mounting options including magnetic strips, hook-and-loop fasteners, and a bench stand make installation simple in virtually any monitoring environment.

Each Traceable® instrument includes an individually numbered Traceable® Certificate verifying accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. Measurements are traceable to SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. This rigorous validation eliminates the need for separate calibration, saving both time and cost.
