LabJack produces low cost, high quality, multifunction data acquisition and control products capable of logging data independently from a computer so that it can be retrieved at a later date. The Digit series devices are battery powered data loggers that let you retrieve saved temperature, light, and humidity data via a USB connection in convenient formats for easy analysis interpretation of collected data. The T7 Series is capable of running Lua Scripts that can be written to acquire data from almost any sensor and saving the result to its internal microSD card.

Update: The Digit has been tested for over a year and is still collecting data. Read the full blog post for more information. If you are looking for capable of other types of measurements we make a variety of DAQ devices that connect to the computer in various ways that are capable of logging data from almost any electrical sensor. LabJack produces USB DAQ devices, Ethernet DAQ devices, and WiFi DAQ devices fulfilling these needs.
To view our USB DAQ product offerings please see our USB DAQ (data acquisition) products. To view our Ethernet DAQ product offerings please see our Ethernet DAQ (data acquisition) products. To view our WiFi DAQ product offerings please see our Wifi DAQ (data acquisition) products.
Please note that the term "DAQ (data acquisition)" implies products that connect to a PC to acquire data. Hence, the term "Modbus TCP DAQ" means that this communication occurs using a PC's active network connection. If you need an instrument that can operate independently from a computer we have Data Logging compatible DAQ devices that are capable of periodically recording to internal memory for later use.
NIST traceable calibration of the U6, T7, or UE9. Includes a calibration certificate.
