LabJack T7
The LabJack T7 is a 16-bit multifunction DAQ with 14 analog inputs, a programmable gain amplifier down to ±0.01 V, a 100 kS/s stream rate, USB and Ethernet, and on-board Lua scripting. The T7-Pro adds WiFi and a 24-bit sigma-delta converter. Engineers use it for thermocouples, load cells and lab logging.

T7 vs T7-Pro
The T7 lists at $570 and the T7-Pro at $850 at the time of writing. Both have 14 analog inputs that pair up as 7 differential channels, ranges of ±10, ±1, ±0.1 and ±0.01 V from gains of 1 to 1000, 23 digital I/O lines and two 12-bit, 0 to 5 V analog outputs. The T7-Pro adds built-in WiFi and a second, 24-bit sigma-delta converter, for which LabJack quotes 16 to 22 bits of effective resolution depending on settings. The Mux80 board expands either model to 84 analog inputs.
Sample rate across channels
100 kS/s is the total stream rate. LabJack’s own example is one channel at 100 kHz or ten channels at 10 kHz each. Internal amplifier settings also affect the achievable rate, so check the data rate tables in the T-series datasheet before you plan a fast scan on the ±0.01 V range. Hardware-timed vs software-timed sampling explains how stream mode differs from command-response reads.
Software on each platform
LJM, LabJack’s free library, runs on Windows, macOS and Linux, and Kipling handles configuration and testing on all three. LJLogM and LJStreamM, LabJack’s logging apps, are Windows only, and LabJack T7 on a Mac goes through the alternatives. The T7 also runs Lua scripts on the device, and its AIN extended features can return thermocouple, RTD and thermistor temperatures directly. DAQAtlas, which is in development, supports the T7 and T7-Pro through LJM, which you install from LabJack.
Questions
Does the LabJack T7 work on a Mac?
Yes. LJM, LabJack’s driver library, and the Kipling configuration app run on macOS as well as Windows and Linux. LabJack’s LJLogM and LJStreamM logging apps are Windows only.
What does the T7-Pro add over the T7?
Built-in WiFi and a 24-bit sigma-delta converter for higher-resolution readings. The rest of the I/O is the same.
Is the T7’s 100 kS/s per channel?
No. It is the total stream rate, shared across the channels you scan, for example ten channels at 10 kS/s each.
