Low Resistance Meters e.g. Micro Ohm Meter, Milli Ohm Meter work with the principle of 4 wire measurement. Two terminals provide test current and two terminals a re used for sensing voltage drop. It is very difficult to buy Low Resistance standards at affordable prices.
ZEAL make, 4 Wire Low Resistance Standard serves the purpose of accuracy and economy. The resistance values are very stable over years. Low resistors of values of 10, 50, 100, 1m, 10m, 100m, 1 have been fitted in an enclosure with provision for each resistors current terminals and drop terminals.

ZEAL make resistance meter is used to measure & sort resistances of winding of motors, alternators, transformers etc. Operator can set upper and lower limits of acceptance using the potentiometers on the panel. LEDs are there to indicate if the measurement is within acceptable limit or not. The product is very reliable and cost effective.

ZEAL supplies highest performance resistance standards. With a very low-temperature coefficient, these highest stability sealed resistance to make an ideal standard for precision applications inside or outside of laboratory environment. Because of the low-temperature coefficient, they require no oil-or-temperature bath. It is possible to maintain ZEAL resistance standards indefinitely. They are reliable due to their closed, rugged design.

Our DC regulated power supplies are widely used in various industries and Educational Institutes. The output voltage produced by DC power supply ranges from 0 to 1000 V and output current ranges from 0 to 100 Amp. Power supply are provided with Digital Panel Meters for voltage and current . They are provided overload and short circuit protections.

It simulates 2-wire transmitter to calibrate receivers, recorders, controllers, indicators. Loop power eliminates the need for batteries. Loop current is clamped at the key value you select. Accuracy is 0.1% of 4 to 20 mA, even with changes in load and supply voltage. Switch settings of 0, 25, 50, 75 and 100% gives user fast, full range check out of UUC. The single rotary switch and light in weight case have been designed for simple, one-handed operation. Just insert the banana to crocodile cables in the banana sockets to the UUC. When you check out receivers, recorders or controllers in a 2-wire 4 to 20mA loop, simply disconnect the 2-wire transmitter and hook up a Model: ZMTCS. Flip a switch to get instant full scale and zero outputs. The calibrator operates just like a 2-wire transmitter by modulating the external power supply voltage into a 4 to 20mA signal.
