Manufactured by Japan's Sato Keiryoki Mfg. Co., Ltd., the Mini-Cube 7-Day Temperature and Humidity Recorder stands as a classic piece of environmental monitoring equipment in both industrial and laboratory settings, as well as a representative category within the realm of scientific instrument collecting.
The device employs a hair-type humidity sensor and a bimetallic temperature sensor, paired with a quartz-driven mechanical movement, to automatically plot continuous 7-day temperature and humidity fluctuation curves on specialized recording paper; it operates autonomously without the need for an external power supply. A digital quartz clock module located on the front of the unit displays the current time in real-time, facilitating the cross-referencing of recorded data; the overall design strikes a balance between the inherent stability of mechanical recording and the convenience of digital display.
The device features a light beige engineering plastic casing complemented by a transparent dust cover, which serves to protect the internal mechanical movement and recording paper from dust and moisture. Additionally, ventilation grilles positioned on the sides ensure optimal contact between the sensors and the external environment, thereby guaranteeing measurement accuracy. A battery compartment located at the base powers the quartz movement, ensuring stable timekeeping, while the recording pen mechanism operates smoothly and without jamming, allowing for the accurate plotting of the environmental curves.
