Profile: Caltest Instruments Ltd. is a distributor of precision electronic test equipment. We also provide power sources and test instrumentation solutions. Some of our products are AC power sources, DC power supplies, AC & DC electronic loads, power analyzers, frequency converters, battery element testers and digital multimeter. Our battery element testers provide a unique method for the detection of assembly level insulation defects in lead-acid batteries, including missing and damaged separators. These developed testers employ a high-voltage, short duration pulse to maximize stress to the dielectric material while minimizing average energy. On the other side 8000 series digital multimeter we provide offer accurate and linearity measurement performance. They use precision foil resistors with temperature coefficients less than 1ppm°C and the latest in analogue chopper stabilized op-amps and low leakage switches.
