Klein 400A HVAC Digital Clamp Meter AC Auto-Ranging A-CL320

Comprehensive HVAC clamp meter measures AC current and NCVT via clamp, and AC/DC voltage, resistance, frequency, DC microamps, capacitance, duty cycle, diode testing, continuity, and temperature via test leads. True RMS (TRMS) auto-ranging technology ensures accurate and efficient readings, even in noisy electrical environments. Built-in non-contact voltage tester (NCVT) integrated into the clamp jaw for added safety. Backlit 4000-count LCD display offers enhanced visibility in low-light settings. Supports temperature measurements using the included K-type thermocouple with a wide range of -40°C to 1000°C. Includes Data Hold and Max/Min value features for in-depth electrical diagnostics. Auto power-off after 10 minutes of inactivity conserves battery life. Durably built with drop protection up to 6.6 ft (2 m) for demanding work environments. Test lead holder and optional magnetic hanger (Cat. Nos. 69445 or 69417) allow hands-free operation. Low-battery indicator and accessible battery compartment for easy maintenance.
