Supports automatic measurement! A multi-point temperature logging device that can operate on solar power even in places without AC power!
The "GTL-100H" is a one-wire temperature profiler that connects up to 60 temperature sensors with a single cable, allowing for simultaneous digital transmission and measurement of temperature. It provides detailed data both spatially and temporally, enabling in-depth analysis of underground thermal energy and groundwater flow. The logger unit and temperature profiling cable are connected via terminals using a thin flathead screwdriver, and it starts up when a DC12V power supply is connected. Additionally, RS-485 is also connected via terminals. 【Features】 ■ Measures standard 51 temperature points at 2m intervals up to a depth of 100m with a single cable ■ The maximum outer diameter of the temperature measurement section is 18mm, allowing it to be inserted into a 25mm diameter measurement tube ■ Measures 50 points in about 1 second, enabling high-precision measurement with a relative error of ±0.2℃ ■ Energy-efficient design powered by a 12V battery ■ The logger has an RS-485 communication port, allowing for remote measurement via radio or mobile packet communication *For more details, please refer to the PDF document or feel free to contact us.
