Data Loggers
Data loggers record temperature, humidity, pressure, voltage and other readings over time, giving you a dependable record for quality checks, compliance and troubleshooting. Most are small, battery-powered units that can run on their own for weeks or months.
Data Logger Types
- Temperature and humidity loggers – cold chain, warehouses and cleanrooms
- Process signal loggers – record 4-20 mA and voltage inputs from transmitters
- Pressure loggers – monitor water systems and compressed air
- Wireless and cloud-connected loggers – view live data and receive alerts remotely
- Multi-channel loggers – log several sensors on one device
What to Consider
Define what you need to measure, the sample rate, how long the logger must run and how you'll retrieve the data. For regulated industries, look for calibration certificates and software with audit trails. Wireless loggers save time when many sites or rooms need monitoring.
Centro offers data loggers and software for food, pharmaceutical, HVAC and industrial monitoring.
