Ethernet (LXI) Instruments for Thermocouples

DT8871U: Highly Accurate Thermocouple Temperature Measurement Instruments

ISO-Channel™ Technology
TEMPpoint™ is a series of temperature measurement instruments designed for high accuracy and industrial robustness. TEMPpoint utilitzes ISO-Channel™ front end architecture to eliminate common mode noise and ground loops through ±500V channel to channel galvanic isolation.
These instruments allow direct thermocouple and precision voltage measurements with a PC. Temperature and voltage values can be viewed, graphed, recorded, and exported to Excel with the free MEASURpoint Framework application.
Ethernet (LXI) versions are available with 8, 16, 24, 32, 40, or 48 channels.
