The SmartReader ACR/SRP 12 Bit data loggers satisfy a wide range of applications;- Temperature, Relative Humidity, AC current, Pressure, Process Signals and Pulses can all be measured and recorded. Extended memory options are available on selected ACR/SRP series 12 Bit devices up to 1.5MB. They are powered by an internal battery with a typical life of up to 10 years and programmed by Windows based TrendReader software. The data stored in the logger can be downloaded and either saved to disk or analysed immediately on screen. Information is displayed in tabular or graphical format with full reporting facilities or alternatively the data can be incorporated into other spreadsheet packages. Refer to page 161 TrendReader software. |  |
