Specifications Resistor values: 10 Ω, 15 Ω, 20 Ω, 30 Ω, 39 Ω, 51 Ω, and 100 Ω Dimensions: 3.5 in long by 2 in wide What's included Vernier Resistor Board Four insulated jumper wires fitted with mini-alligator clips User Manual - VES-RB

The Vernier myDAQ Adapter allows you to connect Vernier sensors to National Instruments’ myDAQ interface.  The adapter includes two connectors for Vernier analog sensors and one connector for Vernier digital sensors. A screw terminal and header pins provide access to myDAQ lines not used by the connectors. This includes the two analog output lines, three digital lines (including the digital lines with the frequency and pulse width modulation outputs), and a +5 volt power terminal. The Vernier myDAQ Adapter board includes an optional external power port. This is designed to be used with Vernier’s LabQuest Power Supply (not included). You might consider using this external power supply if you want an easy way to provide more current to the +5 volt power terminal for building external circuits or to power a servo motor, for example. Easily connect the myDAQ platform to Vernier specialized sensors with this add-on board Access measurements from over 60 Vernier sensors (sold separately) Take advantage of connectors for two analog sensors and one digital sensor Download predefined software examples developed in LabVIEW

This adapter allows an EasyTemp or EasyLink to be connected to a computer for data collection using Logger Pro, Graphical Analysis, or Logger Lite software. The adapter has a USB Mini-A receptacle that connects to the EasyTemp or EasyLink and a standard-A plug that connects to the computer. It can also be used with the USB cable that comes with the CBR 2. User Manual - MINI-USB

An affordable, latex- and phthalate-free accessory, the Gas Pressure Sensor Bulb is designed to be used with the Gas Pressure Sensor to easily perform grip strength measurements. What's included Gas Pressure Sensor Bulb or Bulbs User Manual - GPS-BULB4

The Go Direct Temperature Probe is a rugged, general-purpose temperature sensor that students can use to monitor temperature. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. The rugged, all-purpose Go Direct Temperature Probe gives students the advantage of go-anywhere, work-anywhere connectivity. Because it is also waterproof, Go Direct Temperature is more durable than sensors that are simply water resistant. Unlike a traditional thermometer, Go Direct Temperature allows students to collect real-time temperature measurements of a single instance or over a period of time. Its temperature range and wireless capability make Go Direct Temperature the go-to sensor for real-world applications. The Go Direct Temperature Probe can be used in a variety of experiments: Conduct endothermic and exothermic reactions. Investigate the freezing and melting of water. Measure the energy content of foods. Examine the absorption of radiant energy. Monitor environmental conditions. Rechargeable Battery—Ready When You Are The Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis™ 4 app. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students. Wired or Wireless—The Flexibility to Choose Our Go Direct™ Temperature Probe connects directly to your mobile device, Chromebook, or computer using our free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth, allowing you to choose the solution best for your classroom or laboratory. Specifications Temperature range: –40 to 125°C Handle temperature range: –10 to 45°C Resolution: 0.07°C Connections: Wireless: Bluetooth Wired: USB
