The DATAQ DI-2008 Thermocouple and Voltage Data Logger is a high-performance USB data acquisition system. It is specifically designed for precise temperature and voltage monitoring in industrial, laboratory, and research applications. Featuring 8 differential isolated analogue input channels, the DI-2008 allows each channel to be independently configured for thermocouple or voltage measurements.

Compatible with Multiple Thermocouple Types

Supporting thermocouple types J, K, T, B, R, S, E, and N, the DI-2008 provides accurate temperature measurement with automatic linearisation and cold junction compensation. Voltage measurement ranges from ±10 mV to ±50 V make the system suitable for a wide range of signal acquisition tasks, including 4-20 mA process monitoring using a shunt resistor.

Isolated Inputs for Accurate Industrial Monitoring

With 16-bit resolution and isolated channel architecture, the DI-2008 delivers highly accurate and noise-resistant measurements, even in electrically noisy industrial environments. The integrated USB interface and included WinDaq software enable rapid setup, real-time monitoring, and reliable long-term data logging.

The DI-2008 also includes seven programmable digital ports for switch, counter, and rate input applications, making it suitable for RPM, pulse, flow, and event monitoring. Additionally, ChannelStretch expansion support allows scalability up to 128 analogue and 112 digital channels for larger data acquisition systems.

Ideal Applications for the DATAQ DI-2008

Ideal for process monitoring, industrial testing, thermal analysis, energy systems, and engineering research. The DATAQ DI-2008 offers flexible and reliable thermocouple and voltage data logging in a compact USB-connected platform.

  Set trigger levels to record up to 2G (combined) of pre- and post trigger data (total file size of 4G).
• Seven Digital Ports
  Folds discrete I/O into the measurements process. Each bit is programmable as an input or as a switch.
• Rate Measurement Channel
  Measures pulse rate as may be acquired from a pickup for rpm measurement, or sensor to measure flow.
• Counter Channel
  Tallies the number of pulses applied. Useful for integrating rate information, like flow rate to volume, or simply the number of definable events.
• Software Support
  Supplied with ready-to-run WinDaq software, which records up to four channels at any sampling rate (purchase WinDaq/Unlock to record all channels, or to synchronize multiple units). Also provided with documented command protocol for OS-independent use.

Supplied with: a 6-foot USB cable, a screwdriver for signal connections, and a 32GB USB flash drive containing an NIST-traceable Calibration Certificate and WinDaq software.

*1 WinDaq/Unlock required per device to use ChannelStretch and to record more than four total channels when using WinDaq software.

*2 160 kHz stand-alone dependent on storage card type – refer to the Specifications Sheet
