Vernier Software and Technology has launched five new sensors, including thee designed to provide high school and college science instructors and their students with tools to conduct investigations across many disciplines.
The Goniometer lets users measure the angle of a human joint, such as the knee or elbow. The sensor can analyze the range of motion of a limb during different types of physical activity.
The Vernier Optical DO Probe--with plug-and-play functionality--measures the dissolved oxygen concentration in water. This probe is designed for use in the field or in biology, ecology, or environmental science labs and requires no calibration, no filling solution, no warm-up time, and no stirring. .
The Vernier Radiation Monitor detects alpha, beta, gamma, and X-ray radiation. The monitor can be used to explore radiation statistics, measure the rate of nuclear decay, and monitor radon progeny.
The Ethanol Sensor is used to measure the concentration of ethanol in air above an aqueous sample.
The Pyranometer measures the power of electromagnetic radiation in watts-per-square-meter and is sensitive to near infrared, visible, and UV radiation, where 90% of solar energy is concentrated.
