Floating Contact Null Switch
1640
The unique electric switch design in the 1640 is another Dwyer Instrument, Inc. innovation. The Dwyer Model 1640 Differential Pressure Switch resembles the Series 1630 switches. The Model 1640, however, is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch.

Winding Resistance Meter
TRM 104
TRM104 is a portable winding resistance meter, designed to work in live EHV switchyards. Winding resistance values of large transformers up to 500 MVA and rotating machines are directly displayed. The meter is protected against the back emf offered by large inductive winding. A back-lit 4 line LCD with a user-friendly menu sets up the instrument for the test. Winding resistances and safety messages are also shown on this display. It is possible to measure the resistance of two windings simultaneously.The meter contains a special power source for rapid stabilization of test results.

Ground Earth Resistance Tester
2678X
Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.

SparkFun Decade Resistance Box
This is the SparkFun Decade Resistance Box, an involved PTH soldering kit that allows you to quickly and accurately dial in a specific resistance value between 0 and 999,990 Ω, in 10 Ω increments. The concept is simple, a decade box is a tool that contains resistors of many values that can be accessed via mechanical switches. All you need to do is just adjust the knobs to output any of the discrete resistances offered by the box. Once assembled, each kit will have controls that correspond to the digits in a decimal number - a control for the tens position, a control for the hundreds position, and so on.
