OVERVIEW
The Excelog One combines two essential functions into a single, portable instrument:
- Measure Mode: Read and record temperatures directly from a thermocouple probe. Logged data is saved to the device’s internal memory for quick access later.
- Simulate Mode: Generate a millivolt output to simulate a thermocouple signal at a chosen temperature. This lets you check and calibrate thermocouple-based equipment by connecting the Excelog One in place of a probe.
Whether you’re logging temperature data in the field or testing your instrumentation, the Excelog One makes it simple — no bulky gear or complicated setup required.
Key Features
- Single-channel, dual-function data logger and thermocouple simulator
- Universal thermocouple input (compatible with multiple thermocouple types)
- Simulate a thermocouple voltage for a chosen temperature
- Built-in USB-rechargeable battery
- Backlit colour display for clear readout in any environment
- Simple, intuitive menu and push-button interface
- Multilingual interface (English, Spanish, French, German, Italian, Chinese, Japanese)
- Compatible with third-party Modbus software
Built for Efficiency
A backlit colour display, intuitive push-button controls, and a multilingual menu system make setup fast and straightforward. The built-in USB-rechargeable battery and included USB cable let you download data or power the unit with ease.
Compatible and Connected
The Excelog One communicates via the Modbus protocol, allowing seamless integration with third-party Modbus software. It’s fully configurable and versatile enough for both standalone and PC-connected operation
