SD700 records data to SD card in Excel format. Displays Barometric Pressure in 3 units of measure: hPa, mmHg, and inHg. Triple LCD simultaneously displays Barometric Pressure, Temperature, and Relative Humidity. Datalogger date/time stamps and stores readings on an SD card in Excel format for easy transfer to a PC. Selectable data sampling rate from 5, 10, 30, 60, 120, 300, 600 seconds. Complete with (6) AAA batteries, SD memory card, Universal AC adapter, and mounting bracket.
PIM uses this device as a personal temperature, pressure and humidity meter that is kept on the PIM member’s person and part of the battery of control equipment PIM utilizes for their investigations. This device is better than the Extech RHT50 due to its higher sampling rate of as low as once every 5 seconds versus once/minute for the RHT50. This increased sampling rate does come and a significantly higher cost.
