ACR SmartReader Plus 4 Pressure/Temp/Humidity data loggers

ACR SmartReader Plus 4 Pressure/Temp/Humidity data loggers

ACR SmartReader Plus 4 data loggers are multi-channel, user configurable data loggers that monitor pressure, temperature and humidity. The alarm feature alerts when thresholds are transgressed, via phone or email (external hardware required). These loggers are accessible remotely by modem or device server; multiple loggers can also be linked to form a network. Durability is assured with a 3-year logger warranty and 10-year battery life.

When the sample interval is set longer than 8 seconds, the readings are averaged over the period giving a quantitative result. The software package and USB cable are purchased separately as they can support more than one device.

Faster logging, up to 25 samples per second, is supported using an external power source (USB cable or BP-101 Battery Pack option, see below).
