Since 1989, ISOTEK has been building a solid reputation for quality products and personal service. Backed by more than 25 years of sales experience and an expanded line, ISOTEK is now able to offer a wider range of solutions with cost-effective precision products.

Precision Current Sensing Resistors for power supplies, motor drive controls, electric vehicles, automotive sensing systems and engine management, medical instrumentation, smart battery chargers, welding equipment, etc.

Ultra-Precision Foil Resistors for use in calibration circuits, precision amplifier circuits, or any circuit requiring ultra-precision reference resistors and precision matching and tracking.

HIGH POWER: Metal Clad wire wound resistors from 60W to 1200W in package configurations designed to optimize thermal management. Popular resistance values (inductive and non-inductive windings) to fit most applications in snubber networks, motor braking and for use as a load resistor.

Portable Milli-Ohmmeter, model M210, is a hand-held and battery operated instrument featuring Kelvin (4- terminal) connections.

Voltmeter Current Shunts, models CS-10, CS-20, and CS-30 allow accurate current measurements in ranges of 10, 20 and 30A using your standard DMM.

ISOTEK stands ready to serve you with a knowledgeable and professional staff.
