LabJack produces low cost, high quality, data acquisition (DAQ) and control devices that are compatible with the Modbus TCP/UDP protocol. This means that they can be controlled by many industrial SCADA Systems/Modbus Client Applications, and used natively in any programming language that supports TCP connections. There are several Modbus TCP Libraries available in a variety of different languages.

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.

[1] Can be configured for -10V to +20V range.
[2] According to actual measured data, see related Noise and Resolution (App Note)
[3] If not thermocouple ready, can purchase an amplifier like the LJTick-InAmp, see related Thermocouples (App Note)
[4] The T4 has 4 high voltage (±10V) and up to 8 low voltage (0-2.5V) analog input lines
[5] The U12, UE9, and UE9-Pro are older devices and are not recommended for most new applications. Consider using the T4, T7, U3, or U6.
