Data Logger: Accurate, Continuous Monitoring for Reliable Data Collection

Data Logger Testo Testo 174 H is a compact, powerful device designed to automatically record environmental or process conditions over time. Widely used in laboratories, manufacturing, logistics, food safety, pharmaceuticals, and environmental monitoring, data loggers help professionals collect, store, and analyze data without the need for constant supervision.

Whether you’re tracking temperature, humidity, pressure, voltage, or pH, a data logger ensures precision, reliability, and traceability—making it an essential tool for quality control, regulatory compliance, and research.

What Is a Data Logger?

A data logger is an electronic instrument that records data over time using built-in or external sensors. It stores the data in internal memory or transmits it wirelessly to computers or cloud platforms for real-time monitoring. Data loggers are capable of measuring a wide range of parameters including:

• Temperature

• Humidity

• Pressure

• Voltage

• Light

• Carbon dioxide (CO₂)

• pH and conductivity

• Shock and vibration

They are commonly used for long-term data collection in environments where manual monitoring is impractical or impossible.

How Does a Data Logger Work?

1. Sensors Detect Conditions: Built-in or connected sensors continuously measure specific parameters.

2. Digital Conversion: The analog signal is converted into digital data.

3. Data Storage: Information is saved at programmed intervals in internal memory or external storage.

4. Data Access: Data is retrieved via USB, Bluetooth, Wi-Fi, or cloud platforms for analysis and reporting.

Some advanced models offer real-time alerts, graphical displays, and automated report generation.
