## Description

Product description GME RD-300 Resistance Substitution Decade Box, Designed in The USA The RD-300 Resistance Decade Box is a convenient tool aiding you both in design and testing as well as calibration of your test equipment. When needed to determine the correct resistance value, the RD-300 offers 7 decades of resistance ranges, from 1 to over 11MΩ in 1Ω steps. Slide switches allow for easy addition and subtraction of resistance values. Switches that are in the ON position are clearly marked by a white dot below it to easily distinguish it from those that are OFF. A protective impact resistance case allows the user to prop up the unit for ease of viewing and changing of values. Features 7 decade resistance range from 1Ω to 11,111,110Ω (over 11MΩ) in 1Ω steps 1% high accuracy 1-watt rated resistors 28 slide switches organized in 4 x 7 grid Each switch displays a visible white dot when in the ON position Two binding posts for easy connection with banana plugs, bare wires, spade lugs, or alligator clips Portable and rugged design, housed in protective impact resistant rubber holster with tilt-stand Specifications Resistance ranges 1 to 11,111,110Ω in 1Ω steps Internal Resistance 0.3Ω Power: 1W Resistors Connection Two (2) binding posts Accuracy: 1% Operating conditions: Temperature: 32 to 122oF (0 to 50oC) / Humidity: <80%RH Dimensions: 6” (15.2cm) x 3.5” (8.9cm) x 2.0" (5.1cm) Weight: 0.95 lb (430g) Package Contents One (1) – GME RD-300 Resistance Decade Box One (1) - Protective Rubber Holster One (1) - User Manual

Review: Well made. Sturdy. - A well made unit that I find handy when testing electronic circuits or checking meters.
Review: Wow such a deal! - Decent R-boxes have long been in the hundreds of dollars, prohibitively expensive for little guys like me... up to now. I got this box. put my Fluke 80 on it, and it checked out on all the values. Very nice. The 1 Watt rated power is excellent as it will avoid a lot of inadvertant blowing-out of a value. Darn good R-box. Thanks GME!

### ⭐⭐⭐⭐⭐ Well made. Sturdy.
*by L***R on February 22, 2026*

A well made unit that I find handy when testing electronic circuits or checking meters.

### ⭐⭐⭐⭐⭐ Wow such a deal!

### ⭐⭐⭐⭐ Best I've found - a bit pricey tho
*by T***R on April 28, 2025*

It's a nice quality box. Sturdy box, nicely laid out. Switches work well and feel good (not cheap like some boxes) Accuracy is very good. 1W rating is very handy - not needing to baby it like a 1/4w or 1/2w unit. Binding posts are kinda cheesy. No test leads. A bit pricey but at least it's decent and sturdy.
