Measurement Computing / IOtech DBK81 / DBK82 / DBK83 / DBK84 Expansion Cards

Features
  • Measures Type J, K, S, T, E, B, R, and N Thermocouples as Well as Voltage Up to ±100 mV
  • Low Noise, High Accuracy, High Stability
  • 200 kHz Maximum Scan Rate
  • High Noise Immunity
  • Open Thermocouple Detection per Channel
  • Over-Voltage Protection
  • Four Form-Factors

Description

The Measurement Computing / IOtech DBK81, DBK82, DBK83, and DBK84 Expansion Cards are designed to provide very low-noise thermocouple and milli-volt measurements, with high accuracy and very close tracking between channels. This series provides TC accuracy up to 0.8 °C, and noise typically less than 0.2°C peak-to-peak, with no digital averaging required.

The performance of these new DBK cards is enabled through their use of very low-noise amplifiers on every channel. Built-in cold junction compensation and software-based linearization automatically provide quiet and stable temperature measurements, with no need to deal with the usual complexities associated with TC measurements.


Product Family: DBK81, DBK82, DBK83, DBK84

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
