SmartReader
ACR SmartReader data loggers are multi-channel, user configurable data loggers that monitor a variety of parameters. 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 SR has more available memory as a result of using a 8-bit converter which is sampled 4 times every 8 seconds for extra stable readings. When the logging interval is set longer than 8 seconds, the readings are further averaged giving a quantitative result (with the exception of the SR7 when Battery Switch is enabled). Software Packages are purchased separately as they can support more than one device.
