SmartReader Plus

Multi-channel Alarming Networkable Data Loggers

ACR SmartReader Plus data loggers are multi-channel, user configurable data loggers that monitor a variety of parameters and feature extended memory. The alarm feature alerts when thresholds are transgressed via phone or e-mail*. 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. It is important to note that on competitive products if the replaceable battery comes loose or dies you will not get data - lost time and effort far outweighs any price difference. The SRP uses a 12-bit successive approximation converter for ultra-low power comsumption compared to delta sigma. When the sample interval is set longer than 8 seconds, the readings are averaged over the period giving a quantitative result. Software Packages are purchased separately as they can support more than one device.
