SRP-004 SmartReader Plus 4 Pressure Data Logger

ACR 01-0120 4 Channel Data Logger: Pressure, Temperature and 2 for optional RH/Temp Probes

SmartReader Plus 4 Data Logger: 4 Channels  Pressure, Temperature and 2 for optional RH/Temp ProbesThe SmartReader Plus 4 data logger provides easy monitoring and troubleshooting of pneumatic control systems. The datalogger is completely self-contained with a 1/4” quick-release pressure fitting to allow a fast and trouble-free connection. As an added bonus, this data logger can also monitor temperature internally, or temperature and RH externally. (RH sensors/probes and thermistor temperature probes sold separately).

All ACR Systems Products Have A 7 to 10 Business Day Lead Time.

Fast Sampling with Battery Pack or External 120 Volt Power Supply
For sampling rates faster than once every 8 seconds, the Smart Reader Plus data loggers require the use of an external 120 volt power supply (#PS-201) or fast sampling battery pack (#BP-101).

The fast sampling battery pack has replaceable "AAA" batteries and 8" (20cm) cable attached, with a male stereo jack on the end. The stereo jack is plugged into the communication port on the Smart Reader Plus data logger.

The 120 Volt Power Supply is required when network length is greater than 50' , more than 3 loggers are on the network, or for sampling rates greater than 8 seconds on the SmartReader Plus Loggers.
