Extech EX470A-NISTL True RMS Multimeter w/NIST Cal

The Extech EX470A-NISTL is a 12-function True RMS autoranging digital multimeter with built-in infrared (IR) thermometer, supplied with a Limited NIST Calibration Certificate for applications where documented measurement traceability is required. Functionally identical to the EX470A, it combines electrical measurement and non-contact thermal sensing in a single instrument, while the NIST calibration certificate provides the documentation baseline needed for maintenance records, quality assurance programs, and aviation regulatory compliance. It is the preferred choice for MRO facilities and aviation maintenance organizations operating under FAA Part 145 or ISO 9001 quality management systems where calibrated test equipment documentation is mandated.

Key Features

• NIST Limited Calibration Certificate included, provides documented measurement traceability for aviation maintenance records and QA compliance
• True RMS measurement for accurate readings on aircraft inverter and non-sinusoidal AC circuits
• Built-in non-contact IR thermometer with laser pointer, surface temperature from -4°F to 518°F (-20°C to 270°C), 8:1 D:S ratio
• Type K thermocouple input for contact temperature from -4°F to 1832°F (-20°C to 1000°C)
• 12 functions: AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, temperature, diode, and continuity
• 4000-count autoranging backlit LCD with data hold, MIN/MAX, and relative mode
• CAT III-600V safety rating with double-insulated test leads

Applications

The EX470A-NISTL is the appropriate choice when a documented calibration baseline is required for test equipment used in aviation maintenance under FAA Part 145 repair station standards, ISO 9001 quality programs, or internal calibration tracking systems. The included NIST Limited Calibration Certificate documents the instrument's accuracy at time of manufacture, supporting initial acceptance into a calibration program and providing the traceability documentation required for regulated maintenance environments. It serves the same electrical and thermal diagnostic roles as the EX470A, aircraft electrical system testing, non-contact thermal surveys, and avionics diagnostics, with the added assurance of certified measurement documentation.
