Supported Applications

The Omega OM-20A-TC is a single-channel USB thermocouple data logger designed for temperature measurement. It features an LCD display and direct USB connectivity, intended for use with Windows XP/Vista/7/8 (32 or 64 bit) systems to log, graph, and export temperature data.

Operating Conditions & Performance

The device is powered by a 3.6V lithium battery (included) or via the USB port power source. The LCD display indicates real-time readings in °C/°F units. A specific operational constraint applies to the display: the LCD cannot work at below -10 Celsius degree and will not display normally under those environment conditions.

Configuration Options

The series includes a USB interface for data transfer and power, along with LED indicators that provide status updates on logging activity, alarms, battery levels, and connection states. The following options and accessories are available:

  • 3.6V lithium battery (included)
  • USB driver
  • Data Logger Graph software
  • CD-ROM with software and driver

Key Product Differences

The OM-20A-TC series is identified by the model number guide OM-20A-TC. The device carries CE and RoHS approvals. Users must have administrator rights on the host computer to install the software and USB driver.

Rated 1 out of 5 by from Terrible software, need an actual mini CD drive Bought this for our lab, functionally it's fine but in order to set it up and/or pull the data from it, you need an obsolete CD drive. Pretty ridiculous that the USB driver software isn't either included or availibe on their website. You have to legitimately find a CD drive that can take a mini (4cm) CD.

Hello, thank you for your question. Our miniature connectors accept Stranded or Solid Wire up to Size 20 AWG. Other manufactures may have different specs.
