Vernier Intros Probes and Sensors for Scientific Data Collection
Vernier, a company that specializes in scientific data collection solutions, has released four new scientific testing devices for use in school science programs.
The new devices--an anemometer, a high-current sensor, a 30-volt probe, and a melt station--combine with Vernier's LabQuest handheld devices to enable testing of wind speed, current, voltage, and melting temperatures.
The anemometer is a handheld impeller-type sensor that can be used to quantify power/energy for smaller wind turbines or determine solar thermal system efficiency. It offers the ability to measure wind speeds up to 67 MPH and includes an accessory rod that allows it to be mounted in front of wind tunnels.
For testing melting temperatures, the melt station combines a resistance temperature detector with a range of 30° C to 260° C with a 6x zoom lens for observation. The sensor includes an adjustable tilt for changing the viewing angle and a cooling fan that reduces the waiting period between tests.
The high current sensor is designed to measure current from generators and solar cells. It measures ±10 amps to -10 amps and includes a Hall effect chip to avoid adding resistance while testing.
The 30-volt probe is designed for use in experiments involving more than 10 volts, including those involving larger solar panels.
All four devices are compatible with three different devices: LabQuest, a stand alone tester with a color touch screen and built in analysis software; LabQuest Mini, an interface that's designed to be used in combination with a computer; and Go!link, a little USB device that works with Mac OS X- and Windows-based computers.
The anemometer, high current sensor, 30-volt prob are currently available and ship for $89, $79, and $29, respectively. The melt station will ship in March for $399.
