Product description


NeuLog logger sensor measures voltages, and can be used with Van de Graaff generators, fuel cells, batteries, and parallel and series circuits for further study. The logger sensor has power and ground wires with 4.0mm plugs to connect to electric circuits, and is attachable to the NUL 202 current logger sensor to study current dependence on voltage in various electric circuits (sensor sold separately). The logger sensor has an experiment duration of 50.0 milliseconds to 31.0 days, and 15.0-bit analog-to-digital converter (ADC) resolution for reading a range of values. The logger sensor measures low-voltage AC and DC circuits and, with a step-down transformer, can measure the AC voltage of the main supply and check its frequency up to 50.0/60.0Hz. (Transformer sold separately; the sensor’s input is limited to 60.0Hz and +/-20.0V maximum.) The voltage logger sensor can be used for physics, electronics, chemistry, and biology experiments, and is suitable for grade 3 and higher, or ages 10 to 21.

The logger sensor consists of a data logger, flash memory, and a sensor for fully self-contained data gathering, and is plug-and-play for immediate readings as soon as it is connected. The logger sensor sends data in digital format to a PC, Mac, tablet, smart phone, or other viewer device, and provides multiple connection options, including USB and wireless. The logger sensor’s browser-based software adjusts ranges and gains, and provides applications for presenting data, including online and offline modes, tables, graphs, data analysis, double-axis set up, statistic operations, and mathematical operations. The logger sensor is encased in durable plastic, and has an LED indicator to track experiment status, with push buttons for calibration and start/stop experiments in offline mode for ease of operation. To take an assortment of readings during a single experiment, the logger sensor can be attached to another sensor; one to 10 logger sensors can be used per experiment (sensors sold individually). For efficiency, the logger sensor can store up to five experiments in flash memory, and saved experiments can be uploaded to a PC or Mac at any time. Additional accessories, such as USB, Wi-Fi, or battery modules, are required for operation depending on the device (PC, tablet, viewer, and so on) used to receive readings from the sensor. (Accessories and devices sold separately.) The logger sensor includes a guide with instructions for use and care, and measures 6.5 x 7.0 x 1.5cm (L x W x H). (L is length, the horizontal distance from left to right; W is width, the horizontal distance from front to back; H is height, the vertical distance from the lowest to highest point.)

Logger sensors are electronic devices used to record a variety of energy and environmental measurements, such as temperature, humidity, voltage, and soil moisture, at set intervals over a period of time in scientific classroom and field settings.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

NeuLog brand products, manufactured by EISCO Scientific and Science Educational Systems (SES), include logger sensors, software, and accessories for energy and environmental data acquisition and measurement. EISCO Scientific was founded in 1968, and is headquartered in Rochester, NY; SES was founded in 1983, and is headquartered in Israel. Both companies meet International Organization of Standardization (ISO) standard 9001.
