Vernier Software & Technology has developed four sensors and probes for Vernier LabQuest, which is a handheld interface. The sensors include the anemometer, 30-V voltage probe, high current sensor and a melt station, applying which one can collect and measure scientific data such as wind speed and melting temperatures.
A former physics teacher and the co-founder of Vernier, David Vernier explains that the new high-quality, easy-to-use, affordable equipment meant for both educators and students will help expand the possibilities of science, technology, engineering and mathematics (STEM) education.
Intended for use by all students, the impeller-type, palm-sized anemometer is a sensor used for gauging wind speeds ranging from 0.5 to 30 m/s (1–67 mph) and performing wind study measurements. For wind turbine experiments, it can be positioned facing a fan or in front of wind tunnels using an accessory rod and mounting a standard camera on the back.
In experiments where currents larger than 1 A are involved, such as in solar panels and hand generators, the high current sensor is used. It calculates the current within -10 to +10 A range. While working with large solar panels or in experiments, which involve voltage is higher than 10 V, the 30-V voltage probe can be used. It calculates voltages in the –30 to +30 V range.
Designed for college-level organic chemistry, the melt station determines the melting temperature of solid substances. A built-in RTD temperature detector is used in the 30° to 260°C range and the sensor also comprises a high-quality 6X viewing lens meant for clarity in observation, a cooling fan, which helps gap the time between tests and an adjustable tilt, which offers optimal viewing angle. About 100 standard capillary tubes are included in each melt station.
