Ultra-compact water temperature measurement data logger "Tidbit v2"
Tidobit v2 is an ultra-compact device the size of a 500 yen coin, allowing it to be installed at various measurement points without being location-restricted. It features a fully waterproof (up to 300m depth) and dustproof structure with the log and battery encapsulated in resin, making it effective for measurements in harsh environments. The battery life is approximately 5 years, and it can store up to 42,000 data points, enabling long-term sampling. Additionally, it can be reused as long as the battery life lasts. It also includes a multi-sampling function that calculates minimum, maximum, and average values, making data analysis easier. Communication with a PC is done optically using dedicated communication equipment (USB base station and dedicated software: sold separately), allowing for immediate graphing and tabulation of the collected data.
