There is a wide range of products in the insulation tester category but it is important to choose the right company to provide state of the art products for testing and measurement as they are essential for any engineering or repairing work to be carried out efficiently. Here are a few tips that can help you find the right company to find the insulation tester that matches your requirements:

1.    The company should be able to offer a wide range of products so that you find the ideal one for, that matches your requirements.

2.    The company should have products from different manufacturers across the globe. There is never a just a single brand for any product and a good company will let you explore the options.

3.    They should be able to provide technical services through skilled personnel for their products.

4.    The company should also offer measuring services, calibration assistance and repairing services.

The features that is necessary to make an ideal insulation tester include the following:

1.    Compact: So that they are easy to carry and work with.

2.    Rugged: Such instruments need to bear wear and tear and work in challenging environments without compromising on quality of performance.

3.    Reliable: If the instrument does not match your expectations during a difficult operation, it is not worth keeping in your inventory.

4.    Easy to use: The instrument should allow instinctive operations.

Some of the best insulation testers come from world renowned names like Megger and Kyoritsu and it is important to outline their main features so that buyers can make the right choice.

Megger insulation testers offer you the following advantages:

•    Digital and analogue displays.

•    A variety of test ranges which include five test ranges between 250v to 5000v.

•    Different modes are available which include Insulation, Polarization Index and Variable timed test modes.

•    Voltmeter functions.

•    Frequency selection in AC besides the DC functions.

•    Terminal at guard to shunt surface leakage currents.

•    Designed especially for high voltage insulation resistance.

•    Ideally suited for the following:
 
o    Maintenance and repairing of cables.
o    Plant machineries including the rotating ones.
o    Industrial applications of various sorts.
o    Transformers and switchgears.

The guard terminal is extremely useful when it comes to minimizing the effects of surface leakage. This helps in preventing erroneous measurements while doing the tests.

The Kyoritsu insulation tester offers the following features:

•    It can identify short circuit current as less as 5mA.

•    Offers a wide range of test voltage. (250v – 5000v).

•    Offers a range of Diagnostic Insulation Tests in both breakdown and burn modes.

•    Offers wireless communication by Bluetooth for transferring data and also allows for showing real-time data.

•    Noise reduction and logging functions which allow for a greater stability in measurements.

•    Large back light display including bar-graph indication.

•    Great design for field use which offers robustness and is backed by rechargeable battery.

This insulation tester is also ideally suited for a variety of jobs in industrial applications, transformers or plant machineries.
