Vernier Science Education launches standalone energy meter for schools

Vernier Science Education has released the Vernier Energy Counter, a device built to help students measure the energy produced by renewable energy kits, specifically KidWind wind turbines and solar panels. The meter provides digital readings of total energy in joules after a 30-second testing cycle, operating independently of computers, multimeters, or additional software.

The hardware features a built-in 30 Ω load and supports potentials of up to ±12 V and currents up to ±400 mA. Designed for classroom durability, the rechargeable battery allows for more than 100 testing sessions before needing a charge. This release aims to simplify the data collection process in STEM labs, allowing students to iterate on their turbine and panel designs based on tangible results.

CEO Jill Hedrick noted that the tool is intended to help students practice engineering skills by measuring energy output and adjusting variables accordingly. To support the device, the company is providing free instructional materials that guide students through experiments such as testing different blade pitches. The device is priced at $85 and includes a five-year limited warranty.
