The 195-704-B 4-Channel Analog Data Logger has 16-bit resolution and can record up to 1.9 million measurements. The four external channels accept a variety of analog sensors. The 195-704-B supports the following measurements (sensors sold separately): 4-20 mA, DC voltage, pressure, temperature, evaporation pan level, solar radiation, wind speed and wind direction. Most sensors will require a separate power source. A voltage input cable is required (sold separately). Using HOBOware®, you can easily configure from 1 to 4 sensors. The logger can calculate minimum, maximum, average, and standard deviation statistics. This easy-to-use data logger has a built-in LCD screen to check current readings and to monitor logging status, battery use, and memory consumption in between readouts.
Stored data is collected by a direct USB interface cable connected to a laptop or PC. Graphing: View multiple parameters on one graph, zoom and axis-control tools. Check logger status: Verify logger operation while logging and current readings. Export data to other programs: Microsoft® Excel or other ASCII-compatible programs.
The logger will be setup and programmed with the sensor or sensors that are ordered with the logger.
