Disc Maxi 3 in 1 - Bluetooth Enabled Temperature, Humidity and Dew Point Sensor and Logger

SKU: Disc-Maxi-003

$45.00 USD

One of our most popular Bluetooth-enabled sensors and data loggers, the Disc Maxi offers extended performance in a compact form. Slightly larger than the Disc Mini, it compensates with a significantly longer battery life—lasting up to 5 years under typical usage. It is equipped with a factory-calibrated SHT4x temperature and humidity sensor, delivering excellent accuracy and long-term reliability.

Note: If you have a preference for a specific sensor type, please contact our Sales team. Starting in 2025, all devices will ship with the SHT4x sensor by default, unless otherwise requested.
