These barometric pressure (altitude) and temperature data loggers are ideal for monitoring cleanrooms and laboratories to make sure positive or negative pressure is maintained for safety. As a stand-alone data logger, the unit can record up to 64,000 data points before downloading to a PC. Onboard memory is nonvolatile, so data will not be lost if the battery dies. Alternatively, you can stream data in real time to a PC to keep an eye on changing conditions.

The multicolored LED indicator alerts you to alarm conditions and activity.
