USB data logger enables precise measurement and recording of data for parameters Temperature and Humidity. With a Built in USB interface, you dont need any external USB cables or interfaces to connect with a Computer to download the data.
USB temperature data logger and USB temperature and humidity data logger range is very popular among the users due to the low cost, reliability and convenience in operation.

USB data logger enables precise measurement and recording of data for parameters Temperature...

Our EasyLog USB data logger (also searched as USB datalogger or USB data recorder) range plugs directly into any PC via USB — no external interface cable, no software licence, and no subscription to download your readings. Choose a temperature-only logger (EL-USB-1 / EL-USB-1-LCD), a combined temperature and humidity logger (EL-USB-2 / EL-USB-2+ / EL-USB-2-LCD / EL-USB-2-LCD+), or a thermocouple logger (EL-USB-TC / EL-USB-TC-LCD) for higher-temperature or multi-point monitoring. Models with an LCD display show live and min/max readings on the device itself; all models download logged data free via USB using EasyLog’s own software.

Need continuous, always-on monitoring instead of a USB-download logger? See our Wireless, Bluetooth and WiFi data logger ranges. Need to log voltage, current, CO2 or pressure instead? See our dedicated Voltage, Current, Carbon Dioxide and Pressure Data Logger ranges.

Frequently Asked Questions

Do I need special software to read a USB data logger?

No. EasyLog USB data loggers plug directly into a PC's USB port — there is no external interface cable and no paid software licence or subscription. EasyLog's free software reads the logged data straight from the device.

What is the difference between the LCD and non-LCD models?

LCD models (EL-USB-1-LCD, EL-USB-2-LCD, EL-USB-2-LCD+, EL-USB-TC-LCD) show the current and min/max reading on a built-in screen, so you can check the logger without a computer. Non-LCD models are smaller and slightly cheaper, and are read back via USB only.

Should I choose a temperature-only, temperature and humidity, or thermocouple USB data logger?

Temperature-only (EL-USB-1 range) suits general ambient monitoring. Temperature and humidity (EL-USB-2 range) suits storage, transport and cold-chain applications where humidity also matters. Thermocouple loggers (EL-USB-TC range) accept an external thermocouple probe for higher-temperature or hard-to-reach measurement points.

What's the difference between the standard and ‘+’ (high-accuracy) EL-USB-2 models?

The EL-USB-2+ and EL-USB-2-LCD+ are the higher-accuracy versions of the standard EL-USB-2 and EL-USB-2-LCD, for applications needing tighter humidity and temperature accuracy specifications.

Can I log temperature and humidity data without a network or gateway?

Yes — USB data loggers are designed for exactly this: they record independently on battery power, and you plug them into any PC afterwards to download the full log. For continuous, always-on network monitoring instead, see PST's Wireless, WiFi, Bluetooth or PoE/Ethernet data logger ranges.

Do you stock and support EasyLog USB data loggers in Australia?

Yes. Pacific Sensor Technologies holds local AU stock of the full EasyLog USB range and provides local calibration and technical support.
