COMET U0141T – 4-Channel Temperature Data Logger for 4 External Pt1000 Probes via Terminal Block

COMET U0141T – robust 4-channel temperature data logger for 4 external Pt1000 probes via terminal block (-200 to +260 °C ±0.2 °C), 500,000 values memory, acoustic/optical alarm 

The COMET U0141T is a robust and versatile 4-channel temperature data logger with terminal block connection for up to four external Pt1000 probes – the ideal solution for precise long-term monitoring and documentation of temperature in cold chains, warehouses, climate chambers, cold rooms, transport, pharmaceutical production, food industry, server rooms, heat treatment systems, or anywhere multi-point temperature measurements need to be recorded. With a huge memory of 500,000 values (non-cyclic) or 350,000 values (cyclic), freely adjustable recording interval (1 s to 24 h), and a traceable calibration certificate (EN ISO/IEC 17025), it is perfect for quality management, audits, temperature mapping, and ISO compliance.

The four external Pt1000 inputs via terminal block measure temperature from -200 to +260 °C (±0.2 °C from -50 to +100 °C, ±0.2% of the measured value above, ±0.4% from -200 to -50 °C). The acoustic and optical alarm (buzzer + LED) provides immediate warning when freely adjustable limits are exceeded. Min/Max values are stored. The backlit LCD display is easy to read, and the measurement/alarm update rate is adjustable (1 s, 10 s, 1 min). The logger operates autonomously with a 3.6 V AA lithium battery – operating time several years depending on interval. No power supply required – ideal for fixed and mobile installations. Recording is non-cyclic (stops when memory is full) or cyclic (overwrites oldest data). Real-time clock with date/time. Data transfer to PC via USB-C (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 measurement accuracy from the factory. Intuitive operation via buttons and a clear menu. The compact housing (61 × 93 × 32 mm, approx. 130 g incl. battery) simplifies installation. Whether as a stand-alone logger in production, a mobile tester in service, or as a fixed part of a monitoring chain – the U0141T convinces with precision, robustness, and ease of use. The four Pt1000 inputs via terminal block allow flexible wiring and multi-point measurements (e.g. flow/return, several products or zones).
