NeuLog logger sensor measures dissolved (liquid) or open air (eous) oxygen levels, and can be used to monitor ecological systems, combustion reactions, and oxygen consumption rates for further study. The logger sensor’s attached electrode probe is made of durable polyoxymethylene, which has high strength and hardness, and is resistant to abrasion. The sensor uses polarographic technology for analysis, and has two modes of operation for experiments: open air to test eous oxygen concentration, and dissolved to test liquids for oxygen levels. The logger sensor has an experiment duration of 1.0 second to 31.0 days, with 13.0-bit analog-to-digital converter (ADC) resolution for reading a range of values. The logger sensor’s integral thermistor provides temperature-compensated measurements, and is housed in stainless steel and sealed on the probe’s outer wall for accurate readings. Stainless steel resists scaling and corrosion. The oxygen logger sensor can be used for chemistry, physiology, exercise, biochemistry, biology, environmental, and earth science 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, , 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, , 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.
