COMET U0110 – Temperature Data Logger with Internal Sensor (-30 to +70 °C ±0.4 °C)

COMET U0110 – Rugged Temperature Data Logger with Internal Sensor (-30 to +70 °C ±0.4 °C), 500,000 Value Memory, Acoustic/Visual Alarm 

The COMET U0110 is a compact and extremely robust temperature data logger with an integrated sensor – the ideal solution for autonomous long-term monitoring and documentation of temperature in cold chains, warehouses, climatic chambers, cold rooms, transport, server rooms, archives, offices, greenhouses, or anywhere temperature needs to be precisely recorded without an external probe. With a large memory capacity of 500,000 values (non-cyclic) or 350,000 values (cyclic), freely adjustable logging interval (1 s to 24 h), and traceable calibration certificate (EN ISO/IEC 17025), it is perfect for quality management, audits, and ISO compliance.

The internal temperature sensor measures from -30 to +70 °C (±0.4 °C) with a resolution of 0.1 °C. The response time t90 is 15 minutes (for a 20 °C temperature step and 1 m/s air flow). The acoustic and visual alarm (buzzer + LED) provides instant warning when user-defined limits are exceeded. Min/Max values are stored. The illuminated LCD display is easy to read, and the measurement/alarm update rate is adjustable (1 s, 10 s, 1 min). The logger operates independently with a 3.6 V AA lithium battery – lifetime of several years depending on interval. No power supply required – ideal for fixed or mobile use. Recording modes: non-cyclic (stops when memory is full) or cyclic (overwrites the oldest data). Real-time clock with date/time. Data transfer via USB-C to PC (COMET Vision software).

The data logger is maintenance-free, long-term stable, and comes with a 3-year warranty. The included traceable calibration certificate ensures the highest measuring accuracy from the factory. Intuitive operation via keys and clear menu. The compact housing (61 x 93 x 32 mm, approx. 120 g including battery) with IP67 protection makes it resistant to dust and splashing water. Whether used as an autonomous logger in production, a mobile tester in service, or a fixed element in a monitoring system – the U0110 convinces with precision, durability, and easy handling. No external probe required – ready for indoor measurements right out of the box.
