Klein Tools CL800 Digital Clamp Meter

The Klein Tools CL800 digital clamp meter delivers professional auto-ranging True RMS diagnostics, measuring up to 600A AC/DC current and 1000V AC/DC voltage for residential, commercial, and light-industrial systems. Engineered for electrical technicians, it features a Low Impedance (LoZ) mode to filter out ghost voltages and an integrated thermocouple probe for accurate temperature measurement. Built with a CAT IV 600V safety rating and a durable drop-tested frame, it provides reliable circuit verification across demanding environments.

Best Used For:

  • Commercial Electrical Diagnostics: Measuring live AC/DC voltage and current limits up to 1000V and 600A in commercial building panels.
  • HVAC System Troubleshooting: Monitoring system temperatures from -14°F to 1000°F using the included thermocouple probe.
  • Ghost Voltage Elimination: Filtering out phantom induced voltages in complex wire bundles safely via LoZ mode.

Key Performance & Safety Features

  • True RMS Auto-Ranging: Delivers accurate readings across variable loads.
  • AC/DC Voltage and Current: Measures up to 1000V and 600A for broad applications.
  • LoZ Mode: Identifies and eliminates ghost voltages for safer diagnostics.
  • Temperature Measurement: Thermocouple probe reads from -14°F to 1000°F (-26°C to 538°C).
  • Multifunction Testing: Includes continuity, frequency, capacitance, resistance, and diode testing.
  • NCVT Integration: Built-in non-contact voltage detection for quick safety checks.
