This autoranging megohmmeter measures insulation resistance up to 2000MΩ. Choice of 250,500 or 1000VDC test voltages. The large backlit dual display indicates test voltage output and insulation resistance. Low resistance, continuity and AC/DC voltage measurement functions. Other features include automatic discharge at the end of test, protective holster with stand, power lock on feature and data hold. Complete with test leads, carrying case and 6 AA batteries.
The Extech 380320 is an Analog Insulation Tester with a large, easy to read analog display. It features a live circuit warning which displays the actual AC voltage measurement. It also includes an automatic discharge circuit, lock power on feature for extended test times, and insulation resistance up to 400 MΩ. Complete with heavy duty test leads, alligator clip test lead, 6 AA batteries, hanging strap, and hard carrying case.
With the Extech 380395, measure insulation resistance up to 60 GΩ with test voltages of 500 V, 1000 V, 2500 V, and 5000 V. Its features include polarization index measurement (PI), dielectric absorption ratio measurement (DAR), AC/DC voltage measurement up to 600 V, peak and relative functions, and a 1 min to 15 min timer function for IR measurements. Comes with test leads, eight C batteries, 120 V AC adaptor, heavy duty carrying case, and a user manual.
With the Extech 380396, measure insulation resistance to 60 GΩ with test voltages of 500 V, 1000 V, 2500 V, and 5000 V. It features several measurements including polarization index (PI), dielectric absorption ratio (DAR), and AC/DC voltage to 600 V with a min/max function. It also has peak and relative functions, as well as a 1 to 15 minute timer function for IR measurements. Comes with test leads, eight C batteries, 220 V AC adaptor, heavy duty carrying case, and user manual.
The Extech 380400 Resistance Decade Box is very popular for product design testing and calibration because it can be substituted into a circuit and function in the place of any component with a standard value easily. Alternatively, it can be used to identify the best value for circuit operation then read that value from the switches. Then, a resistor of the size indicated by the decade box switches can be put into the circuit.
The Extech 380405 Capacitance Decade Box is very popular for product design testing and calibration because it can be substituted into a circuit and function in the place of any component with a standard value easily. Alternatively, it can be used to identify the best value for circuit operation, then read that value from the switches. A capacitor of the size indicated by the decade box switches can then be put into the circuit.
High accuracy and performance for low resistance measurements. Portable milliohm meter provides resolution to 0.1mΩ. Compact, durable field service housing with protective cover. Manual zero display adjust and overrange indication. Complete with 4-wire cables with Kelvin clip connectors.
Compact and precise, the Extech 380562 Milliohm Meter has 7 ranges and measures down to 0.01 mΩ using 4-wire Kelvin clip test leads. Measurements are displayed on the unit's large 20.3 mm (0.8 in), 1999-count LCD. It comes with a built-in comparator for Hi/Lo/Go resistance testing or selection. Complete with 4-wire cables with Kelvin clip connectors and power cord.
