REED R6250SD-NIST

The R6250SD measures temperature, humidity, and direct or radiant sunlight with Wet Bulb Globe Temperature (WBGT). With this information it determines the "what it feels like" temperature. The R6250SD is designed to meet OSHA requirements, with a user-adjustable WBGT audible alarm and the ability to adjust settings for indoor temperature measurement. Featuring, Data hold, Max/Min functions, and an easy-to-read backlit LCD display. Using a SD card (max 16GB), a user can manually record up to 99 readings or do so automatically by selecting a desired sampling rate from 1 to 3600 seconds. Quickly generate an Excel file with raw data, all without the use of software. Optional accessories include a tripod and AC adapter for continuous long-term monitoring.

This product includes a Traceable Calibration Certificate with full Data and Uncertainties.

The Occupational Safety and Health Administration (OSHA) recommends the use of Wet Bulb Globe Temperature (WBGT) heat stress monitors to ensure safe working conditions are met. The R6250SD considers temperature, humidity, and direct or radiant heat to determine the "what it feels like" temperature.

Save yourself a lot of work with the data logging features of this model. As a data logger, its capacity to automatically monitor and record environmental parameters over time, allow conditions to be measured, documented, analyzed, and validated in 3 easy steps.

1. Insert memory card

2. Record the needed data

3. Insert memory card in PC and open with Excel

The REED R6250SD Data Logging Heat Stress Meter comes complete with a carrying case and batteries.
