KYORITSU KEW 2127R AC Clamp Meter (Made In THAILAND)
The KYORITSU KEW 2127R AC Clamp Meter (Made In THAILAND) is a handheld AC digital clamp meter engineered for field technicians who need a dependable, one-handed instrument for inspecting electrical systems. Its design centers on giving clear, legible readouts and intuitive controls so users can quickly verify circuit conditions without removing conductors or interrupting service. The housing balances ruggedness with ergonomics, keeping the meter comfortable during repeated use while protecting internal circuitry from everyday knocks.
Internally the meter combines precise signal acquisition with on-device processing to present stable measurements for both steady-state and transient events. The clamp jaw allows non-contact clamping of conductors up to the rated diameter, and the instrument’s user interface groups key operations range selection, hold, and peak capture within easy thumb reach. The display and controls are arranged to reduce chance of error when working in dim or cramped locations.
Built as part of a product family that spans basic to advanced models, the 2127R targets tasks where verifying current, voltage and signal presence rapidly is essential. The documentation stresses safe operating practice and clear safety markings; the meter is presented as a practical tool for routine inspections, troubleshooting and verification work across a variety of electrical environments.
Features:
- True-RMS measurement for accurate readings on non-sine loads.
- Peak-hold function for capturing inrush/current transients (2127R only).
- Backlit LCD for visibility in low light (2127R only).
- Non-contact voltage (NCV) detection with LED indicator.
- Ergonomic over-molded body for single-hand operation.
- Fully guarded clamp jaw for safe conductor access.
- Large, easy-to-read display with 0.01 A resolution on relevant ranges.
