LogBox microT

Mobile high precision thermometer
with integrated data logger,
very high resolution (0.0003°C)

The LogBox microT is a complete autonomous measurement system, consisting of a high precision thermometer with integrated power supply and data logger and an additional sensor cable with several temperature sensors. It combines the high accuracy of a laboratory instrument with the robustness of a field measurement device.

A weatherproof casing protects the instrument from rain, dirt and dust (protection IP65). Disturbing influences on the measurement device, like temperature changes between day and night or decreasing battery voltage, are compensated reliably. Thus, the LogBox multiT always provides you with precise measurement results even under difficult measuring conditions.

We customize every sensor cable to perfectly meet your specific requirements - with up to 3 individually calibrated temperature sensors over a maximum cable length of 300 m. Each sensor is protected by a stainless steel capsule that is waterproof to 300 m depth.



LogBox - Series and Features

The high precision thermometer LogBox microT works very energy-efficient. There are battery holders for 3 standard D-size batteries integrated into the casing. They provide enough energy to run a maintenance-free measurement for several months. For even longer unattended measurements there is an additional power connector to apply external 12-V power sources, like car batteries or AC-adaptors.

No tools are required for deployment or maintenance of the LogBox. Measured data are stored in a text file on a removable USB memory stick, which can be read on every computer.

An efficient and easy-to-use data processing software for fast visualization, averaging and printing of measured data is included in the scope of delivery.

Due to its extraordinary high accuracy, the LogBox microT is not only a good choice for applications where temperature is in the focus of interest. More than that, it enables you to measure other physical properties and processes indirectly, like the water flow in aquifers or waters.
