Contact Resistance Test Sets
-
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.

Contact Resistance Tester
JYL
-
As a high current passes through a pair of mechanically independent metallic contacts, the contact resistance must be as low as possible. Increasing the contact resistance of the contact often causes a large voltage drop on the contact, which reduces the input power of the load equipment. If the contact resistance of one or two contacts becomes large, the three-phase voltage of the load equipment will be unbalanced, causing phase loss operation.

Contact Resistance Measurement System
CRMS
-
The CRMS is a system designed to allow any user to measure the resistance of each set of relay contacts associated with the relay under test. The test system consists of a CONTACT RESISTANCE MEASUREMENT UNIT (CRMU), a MULTIPLE RELAY TEST RACK, as well as an interconnect CABLE ASSEMBLY. Either DC or AC energy to pick and drop relay coils under test for all contact measurements is supplied from the CRMU and easily interfaces with the Multiple Relay Test Rack. For additional and more thorough testing of relays an external relay tester can be interfaced to the Multiple Relay Test Rack to supply energy to the relay coil. It is recommended that the UTE Relay Tester With Timer/Counter (UTE Product # 15967-00) be utilized so the operator can take full advantage of the unique features it offers

200 Ampere Micro OHM Meters
HL-200
-
Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 200 is a direct reading tester, and uses a test current of 200A DC, resulting in true value and accurate measurements. Model HL- 200 adopts digital circuit technique and is used for measuring contact resistance of switch control equipment at test current of 200A DC. The measurements are accurate as the test is highly stable. HL- 200 is a new, fully automatic micro controlled tester that measures contact resistance at 200A DC with built in printer.

Qmax Test Technologies Pvt. Ltd.
QT25 employs a unique method to detect exact PCB shorts circuit locations and pin down the shorted components and tracks. It is designed in such a manner that it precisely detects exact short circuit locations across VCC - GND or a shorted component connected across a Bus or hair-line shorts between PCB tracks, Which is highly impossible to detect using conventional tools especially when they are connected parallel in circuit. It can also be used in measuring the contact resistance of switches and relays in its milli-ohm mode as a value add.
