Single channel datalogger
Our single channel data loggers are perfect tools for monitoring and recording data in environments where measurement of a specific parameter is necessary. Simple to set up and use, these devices are ideal for tracking variables such as temperature, humidity, pressure or light levels, recording reliable data continuously.
Technical FAQ:
Single channel datalogger
What is a single-channel data logger?
It is a data logger dedicated to recording a single physical quantity (e.g. only temperature, only humidity), compact, economical and optimized for monitoring a single measurement point.
What is a single-channel data logger used for?
It is used to continuously and autonomously monitor a single variable at a specific point: the thermometer of a refrigerator, the humidity of a warehouse, the temperature in pharmaceutical transport. It is the most widespread solution for the cold chain and for point monitoring.
In which sectors is a single-channel data logger used?
It is used in the food and pharmaceutical cold chain, refrigerated transport, monitoring of cold rooms, freezers and incubators, archives and museums, agriculture, structural monitoring and in all contexts where a single parameter needs to be recorded over time.
When to choose a single-channel data logger instead of a multi-channel or IoT one?
The single-channel is chosen when only one parameter needs to be monitored at a single point, when the budget is limited, or when many data loggers are distributed across multiple points. The multi-channel is preferable for complex environments with multiple variables; the IoT data logger when real-time remote access is required.
What are the most common single-channel data loggers?
The most widespread are temperature data loggers (with NTC or Pt100 sensor), combined humidity and temperature (although "two quantities" are technically still considered single-channel for commercial use), CO₂, pressure, shock/vibration for transport and on/off events (door opening, light presence).
Are single-channel data loggers disposable or reusable?
Both versions exist: disposable units are designed for a single transport (e.g. pharmaceutical shipment), with contained unit cost and PDF report automatically generated at the end; reusable units are used for years with periodic battery replacement and annual calibration.
How much do single-channel data loggers store?
Typical memory ranges from 8,000 to 32,000 measurements, sufficient to record even an entire year at hourly frequency. Advanced models have expandable memory and "rolling" mode that overwrites the oldest data for indefinite duration recordings.
Can single-channel data loggers be used for pharmaceutical transport?
Yes, they are the standard tool for transport according to EU GDP (Good Distribution Practice) guidelines. Disposable data loggers are inserted in the package before shipment and produce at the end a digitally signed PDF report, attachable to the delivery documentation.
Do single-channel data loggers have a reading display?
Some models integrate an LCD display for immediate reading of the current value, min/max and alarm status. Other models are "blind" (without display) and data is only visualized after downloading via PC, NFC or Bluetooth.
Are single-channel data loggers certified for GMP use?
Professional models comply with 21 CFR Part 11 and EU GMP Annex 11, with audit trail, electronic signature and traceability. They are used for thermal mapping of warehouses and cold rooms, continuous monitoring of pharmaceutical refrigerators and validation of thermal processes.
How long do single-channel data loggers last?
Reusable models have a useful life of 5-10 years with periodic lithium battery replacement (1-3 years depending on consumption). Disposable models are designed for durations from 30-60 days up to 100 days in a single trip.
Do single-channel data loggers need to be calibrated before use?
Yes, professional reusable data loggers must be calibrated annually with ISO/IEC 17025 accredited certificate. Disposable units are supplied by the manufacturer already calibrated with factory certificate.
