These
sets have facility for checking insulation resistance in the range of
1 meg ohm to 10 million meg ohm after one minute of charging.
Intrinsic value of insulation resistance if required, even with
capacitive loads. Separate push button controls and visual indicators
for "Charge", and "Discharge" function are
ideally suited for rapid and safe testing of components in a factory. Maximum output current has been limited to safe value to eliminate
the risk of
serious shock to operators. The instruments are available in two models
as per specifications given overleaf.

A well planned and effective earthing of electrical equipment is essential for the safety of electrical establishments and their operational excellence. The efficient operation of an electrical plant, sub-station and factories depends upon the earthing electrode resistance. So, we offer well designed instruments called earth testers carrying the vital responsibility of maintaining the earthing resistance at a lower value and within the prescribed maximum limits. The earth testers we offer are sturdy and portable, easy in usage and highly durable. Our earth testers are applied for measurement of earth-resistivity which is the easiest way of planning out the locations that are best suited for installing the earthing electrodes which are to be used for geophysical surveying and investigating the setbacks concerned with the soil like corrosion etc. These earth testers are also applied for the accurate measurement of the prevailing earthing electrodes and maintaining electrical connections more...
The most commonly used method to evaluate print quality is by rubbing 2 printed surfaces against each other. However if this is done manually, the amount of pressure applied during rubbing cannot be quantified and kept constant. Moreover it is difficult to keep the plane of contact constant and keep a track of the number of rubs. Hence making this method highly Operator Dependent.

The contact resistance meters we offer in the market are used for effective and accurate measurement of the resistance of male-female contacts of isolators, GTS breaker contacts, bus bar joints and SF-6 breaker contacts. It is done by applying a variable DC current ranging from 0–100 amperes and measurement of the voltage drop along their contacts. We have housed it in an unbreakable body made from FRP (Fiber Reinforced Plastic) within MS fabricated box for easy transportation to prevent it from any kind of damage. The ammeter and millivoltmeter (Micro-ohmmeter) measures the current flowing in the contacts of the electrical equipment. A variac incorporated to adjust the output current from 0 – 100 ampere.
