LogBox multiT

Mobile precision thermometer
with integrated data logger,
high resolution (0.015°C)

The LogBox multiT is a complete autonomous measurement system, consisting of a 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 IP67). 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 10 individually calibrated temperature sensors over a maximum cable length of 200 m. We offer you two different sensor encapsulations:

   a) plastic jacket - for minimum space requirement:
       10 mm diameter, waterproof to 100 m depth
   b) stainless steel capsule - for maximum water depth:
       22 mm diameter, waterproof to 200 m depth

LogBox - Series and Features

The precision thermometer LogBox multiT 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.

The measurement data file can be imported into all common spread sheet applications (e.g. MS Excel, LibreOffice Calc), which can be utilized to perform data processing and visualization.

Due to its high accuracy and the selection of sensor encapsulations, the LogBox multiT 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 concrete penetration depth during cementation of (geothermal) boreholes.
