AC/DC MicroProbe Model K110 (450 mA, 10 mV/mA)

The K110 AC/DC Microprobe is built for the low end. It reads currents as low as 50 µA DC (150 µA AC) up to 400 mA peak — AC and DC — and outputs 10 mV per mA. That's ten times the signal-per-amp of a standard AC/DC clamp, giving you cleaner waveforms on your oscilloscope and finer resolution on your DMM in the ranges where every microamp counts.

Same slim jaw as the K100 probe. Same non-intrusive clamp-on measurement. Different scaling — tuned for the bench, the R&D lab, and the process-control loop where low-current accuracy is everything.

Why the K110 Probe

High-gain 10 mV/mA output
Sub-milliamp resolution
Scope-ready waveform capture
True AC and DC in one probe
Non-intrusive 4-20 mA loop verification
Slim jaw for crowded wiring.

APPLICATIONS

WHERE THE K110 SHINES
- Industrial & Process Control - Calibrate and troubleshoot 4-20 mA process control loops without ever breaking the circuit.
- For controls engineers, calibration techs, and field service techs
- Electronics R&D Test Labs - Scope-ready 10 mV/mA output for capturing low-level current waveforms no standard clamp can see.
- For design, bring-up, and validation engineers

ALSO WELL-SUITED FOR
- Battery & Low-Power Electronics - Sub-milliamp precision for IoT and embedded devices, down to 50 µA.
- Automotive Electronics - Precision parasitic-draw diagnostics in the microamp range.
- EV & E-Mobility - 12 V parasitic draws and BMS sense-line troubleshooting.
- Energy & Renewables - Non-intrusitve standby and low-string measurement on solar/PV systems.

Also serving: Avionics & Aerospace, Medical Devices, Data Centers, Defense, Marine, and Drones/UAS.

ALSO CONSIDER

Model K100 — If your work goes above 400 mA and up to 4 A, or you want a single probe that covers a broader current range for general troubleshooting, look at the K100. Same slim jaw, lower output gain (1 mV/mA), wider window.
