True RMS Multimeter with Temperature Fluke 116
This digital multimeter with Manual Ranging and True RMS technology delivers specialized precision for professional applications. It measures AC/DC voltage, resistance and micro-current, plus a dedicated temperature input. Rated CAT III 600V for safety, it is ideal for heating, refrigeration and air conditioning technicians.
Specialized Precision for HVAC Professionals
Built for HVAC technicians and industrial applications, this measuring instrument combines manual-range precision with dedicated temperature and micro-current measurement functions.
Key Features
- Manual Ranging: gives full control over the measurement range, ensuring a stable reading during sensitive, repeated measurements.
- True RMS Measurement: delivers accurate voltage and current readings even on non-sinusoidal signals.
- Temperature Measurement -40°C to 400°C: via K-type thermocouple, ideal for checking heating, refrigeration and air conditioning systems.
- Microamp Current Measurement (µA): a dedicated function for testing flame rectification current on burners.
Frequently Asked Questions
Q: What is True RMS and why do I need it?
A: True RMS (Root Mean Square) multimeters accurately measure AC current and voltage even when the signal isn't a perfect sine wave, which is common with modern electronics and variable-frequency drives.
Q: Why does this model use manual instead of automatic ranging?
A: Manual ranging gives the technician full control over the measurement, which is especially useful in specialized HVAC applications where a stable, predictable reading is needed without automatic range switching.
