IET Labs Resistance Substitution Box, Model RS-201, 0.1% Accuracy, Size: 3.2" x 3.1" x 2.2"

This Resistance Substitution Box, Model RS-201, offers an impressive 0.1% accuracy rate, while taking direct readings for convenience. The individual value ranges are demarcated with color-coded switches and numbers, making it incredibly easy to read. Furthermore, the box is highly portable and built with rugged durability, measuring just 3.2" x 3.1" x 2.2".

Features:

• Direct reading — No fumbling with multiple slide or rotary switches
• Standard accuracy of 0.1%
• Direct readings eliminate potential mistakes that come from rotary or slide-switch boxes.
• For easy value readings, ranges are separated by color-coded switches and numbers.
• The units are small, rugged, and portable.
