AEMC Ohmmeters are Available for Rent from Protec

by Protec Tech Team September 28, 2017

Ohmmeters are an electronic device that measure electrical resistance, and come with different levels of sensitivity. Some are designed to measure low-resistance materials, while others measure higher resistance. The higher resistance the material has, the less current will pass through it.Contact Us Now

An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through various parts of the circuit, although it can be used to test that a circuit is not broken.


Protec Offers Range of Insulation Resistance Test Equipment for Rent

by Protec Tech Team July 25, 2017

Electrical current flowing through a conductive wire should reach its intended destination. However, it is possible that some of the current may be lost along the way for various reasons.

AEMC 1026, A Digital Megohmmeter with Numerous Appplications

by Protec Tech Team December 01, 2016

Megohmmeters are design to measure very high resistances usually greater that 1 MegOhm or 1,000,000 Ohms. 

They are used to measure the resistance of insulating materials and to determine at what voltage the insulation will "break down" and allow a current to flow through it. 


Rent the AEMC 6416 to Measure Ground Electrode System Resistance

by Protec Tech Team September 26, 2016

When verifying grounding resistance, a clamp-on tester makes it simple by simply clamping the sensor around the connection at the ground rod, and reading the resistance on the display of the instrument.


Rent AEMC 6416 Clamp-On Ground Resistance Tester for Easy Diagnostics

by Protec Tech Team August 16, 2016

Performing resistance measurement of a grounding system ensures that the grounding rod has good contact with the earth. The resistance of the grounding system to the earth may be affected by several factors like dry ground, partially uprooted stake, corroded connections and broken ground leads. 


Test Resistive and Inductive Material with AEMC 6250 Micro-Ohmmeter

by Protec Tech Team July 22, 2016

The AEMC 6250 10A Micro-Ohmmeter is an accurate Micro-Ohmmeters with results up to 0.05% high accuracy, utilizing a four-lead Kelvin method of testing,

With the AEMC 6250 10A Micro-Ohmmeter resistance measurements are automatically calculated and displayed, taking into account the measurement value, ambient temperature, reference temperature and metal temperature coefficient. Sample temperature can be manually entered by the operator or directly measured by the AEMC 6250 10A Micro-Ohmmeter with an external RTD temperature probe.

Test Ground Resistance and Bonding with the AEMC 6416

by Protec Tech Team May 26, 2016

It's possible to eliminate many power quality problems with proper wiring, good grounds, and the bonding to the ground system. Testing grounds and bonding should always be part of any power quality troubleshooting strategy, and one effective method is to use a clamp-on ground tester.


Four Functional Tests in One Megohmmeter with the AEMC 1026

by Protec Tech Team May 17, 2016

Measuring the quality of insulation involves checking the insulator’s resistance through the use of a megohmmeter. Acceptable insulator resistance values are typically 1 to 10 megohms, depending on the standards referenced. 


Specifications for the AEMC 6416 Clamp-On Ground Resistance Tester

by Protec Tech Team April 13, 2016

Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test. The AEMC 6416 Clamp-On Ground Resistance Tester clamps around the grounding electrode or conductor and measures the resistance to ground.

By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
