The Eastwood QR101B-2M-RX resistance decade box can output desired resistance, making it very useful for prototyping, measuring or analysing.

It features a electronically controllable switch, a modern user interface with a keypad for input and a mini OLED screen for displaying by default the Step-point (SP), resistance Process Value (PV) and max voltage allowed (U<) of PV.

The Plug-and-play USB port supports any free/open source serial software, supporting ASCII type AT style commands. It is also used to charge the 300 mAh Li-Polymer battery, with 500+ charge/discharge cycles and an 12 hour battery life. Furthermore, it features a user calibration function which can be very useful for maintenance.


The models primarily differ in resistance range, resistance stepsize and accuracy.
