About

Theta

Read full description

Theta-Meter X Theta-Meter X is a companion application designed to work with compatible Theta-Meter hardware devices.  The app connects via Bluetooth Low Energy (BLE 4.0 or higher) or Wi-Fi and displays real-time electrical resistance  measurements from objects connected to the device’s electrodes. Key Features: - Real-time visualization of electrical resistance changes - Clear analog-style needle indicator for dynamic monitoring - Bluetooth LE and Wi-Fi connectivity - Simple, user-friendly interface - Stable data transmission from supported hardware devices How It Works When connected to a compatible device, the app measures and displays variations in electrical resistance detected between  attached electrodes. The needle indicator provides a continuous visual representation of resistance fluctuations, allowing  users to observe dynamic changes over time. Intended Use Theta-Meter X is designed for general experimental, educational, and technical purposes involving electrical resistance measurement.  It is intended for use with compatible hardware devices only. Important Notice This application and the associated hardware are not medical devices. They are not intended for diagnosing, treating, curing,  preventing, or mitigating any disease or health condition. The app does not provide medical, therapeutic, or psychological advice.
