B+K Precision produces a complete line of test and measurement accessories that connect a meter, oscilloscope, or analyzer to the device under test. The line includes DMM test lead kits, economical replacement leads, general-purpose and high-voltage oscilloscope probes, demodulator and active probes, a clamp-on current adapter, BNC cable assemblies and adapters, semiconductor and power-supply leads, and padded carrying cases.

These accessories support a broad range of bench tasks. The DMM kits attach probes or clips to a sheath plug for electronic and electrical voltage and current work; the oscilloscope probes extend a scope's versatility across fixed and switchable attenuation; the CP-3 adapter converts any DMM into a current clamp, measuring current without disconnecting the circuit under test; the PR-650A and PR-32A demodulator probes let a meter or scope read RF signals; and the FP-6 leads connect to B+K Precision semiconductor testers.

ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.

Compare Other Models in This Series

B+K Precision's accessory line is organized by function rather than by a single performance tier. It brings together DMM lead and probe kits, replacement leads, a family of oscilloscope probes (general-purpose, high-voltage, demodulator, differential, and active FET), current-measurement adapters, BNC cables and adapters, and instrument carrying cases.

Many items share common construction—flexible silicone lead wire, 4 mm sheathed connectors, and compliance with IEC 61010 safety standards where rated—while each is selected for a particular instrument hookup or measurement task.

Each new model below is its own dedicated product page with condition-matched pricing. Select the specific accessory you need to see its new availability and current price.

The models differ mainly in their electrical ratings and intended connection. Lead and clip sets carry ratings from 300 V CAT I up to 1000 V CAT III with current ratings from 3 A to 36 A, while economical replacement leads such as the TL-1 and TL-4 are rated 1500 V, 3 A. Oscilloscope probes differ in attenuation (x1, x10, x100, x1000, and switchable), bandwidth, input impedance, and voltage handling.

High-voltage probes step from 2 kV through 15 kV, the PR-28A high-voltage DMM probe reaches 40 kV DC, and cable assemblies vary in length and connector type. The comparison table below lists each model's specific ratings so you can match the accessory to your instrument and measurement.

Model Type Voltage Rating Current Rating
PR-28A HV DMM Probe 40 kV DC / 20 kV AC
TL-50 DMM Accessory Kit 1000 V 36 A
TL-10 SMD Probe Kit 1000 V
TL-130A DMM Accessory Kit 1000 V 36 A

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.
