NUL248 Neulog mA Current logger sensor module is used to measure the current in the mA range, in parallel or series branches of low voltage AC and DC circuits and also to investigate the dependence of the current flow through components on the voltage across them. Includes red (positive probe) and black (negative probe) wires connected directly to the sensor's body. The wires are attached to 4 mm red and black plugs. With its 4 mm plugs it can easily be connected into electric circuits. Specifications: Range and operation modes +/- 250mA, ADC resolution 15 bit, Accuracy 1%, Resolution 0.1 mA, Maximum sample rate (S/sec) 3,000 short duration. This logger sensor can be use on ipads, tablets, PCs, and Macs (devices sold separately). "Required accessories-To use sensors you will need either: a USB Module (USB 200) to connect via USB cable to PC or Mac, or a Wi-Fi Module (WIFI201) and battery (BAT200) to connect to any Wi-Fi enabled device (Smart Phone, Tablet, Computer)" The module is suitable for grade 3 and higher, or ages 10 to 21. Measurements with NeuLog sensors can be performed through any device which uses the Wi-Fi technology, such as iPads and Tablets with Android, PC computers with Windows / Linux or Macintosh with OS. These can all communicate with the Wi-Fi adaptor to begin a unique experience of data acquisition. There is no need for any application download or software installation to take advantage of all the power of NeuLog sensors through the wifi module.
