Digital measuring computer complex for chemistry teacher

Digital Computerized Measurement System for Chemistry

The wireless sensors are equipped with a 1.8-inch color LCD screen that immediately displays measurement results for conducting experiments.

The wireless sensors operate autonomously without additional devices or wires, specifically without a data logger or other analog-to-digital converter to transmit measurement results to a computer or tablet.

The digital course includes a separate tool utilizing artificial intelligence technologies, including capabilities for applying generative artificial intelligence.

The digital lab is a modern educational solution that combines software, multimedia content, and artificial intelligence elements to support inclusive and engaging learning.
