REED R4700SD Offers

The R4700SD is a 6-in-1 environmental meter that measures air velocity, air temperature, ambient temperature, relative humidity, light and contact temperature measurements. Has the ability to capture sound level measurements using the R4700SD-SOUND adapter (optional). The R4700SD features 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 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.
