Real-time data logger with integrated SD memory card measures/records oxygen, carbon dioxide, carbon monoxide, ambient temperature, dew point and wet bulb temperatures and humidity.
Real-time data logger with integrated SD memory card measures/records oxygen, carbon dioxide, carbon monoxide, ambient temperature, dew point and wet bulb temperatures and humidity.
The R9910SD is capable of recording readings from 3 probes simultaneously and 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 sec to 8 hours. 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.
