195-704-B 4-Channel Analog Data Logger

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 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: 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 and an input cable to connect to the logger. The logger can calculate minimum, maximum, average, and standard deviation statistics.

HOBOware® software is used to configure from 1 to 4 sensors and manage downloading data. Stored data is collected by a direct USB interface cable connected to a laptop or PC. The software can display multiple parameters on one graph, and includes zoom and axis-control tools. Data may be exported to other programs such as Microsoft® Excel.

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. The logger will be setup and programmed with the sensor or sensors that are ordered with the logger. The logger is available either stand-alone or in a weatherproof enclosure.
