Check surface temperatures without contact, then use a suitable contact probe when you need a reference reading. The Anritsu AR-6500 series infrared thermometer brings both methods into one handheld instrument for production checks, maintenance and temperature investigations.

Anritsu AR-6500 series infrared thermometer with contact measurement capability

Contact reference for emissivity adjustment

Infrared readings depend on the surface being measured and its emissivity. The AR-6500 series supports automatic emissivity setting using a contact-type probe, helping you establish a setting for the target surface.

Select a probe suitable for the material, temperature and surface shape. A reliable reference requires stable contact with the same area being checked by infrared measurement. Contact probes are not included with the instrument.

Select the temperature range and output

ModelInfrared rangeMeasurement spot at 500 mmAnalog output
AR-6500 -50.0 to 500.0°C Ø19 mm Not provided
AR-6501 -50.0 to 500.0°C Ø19 mm 1 mV/°C
AR-6500-H 0 to 1200°C Ø12 mm Not provided
AR-6501-H 0 to 1200°C Ø12 mm 1 mV/°C

Field of view and target size

Choose the measuring distance so the target fills the measurement area. A target smaller than the spot can allow the surrounding surface to influence the result.

AR-6500 contact measurement specifications

Input Type K thermocouple with ANP miniature connector
Instrument range -50.0 to 500.0°C; use within the connected probe's rating
Instrument accuracy ±(0.05% of reading + 0.1°C) ±1 digit
Sampling interval Approximately 300 ms

These contact specifications apply to the AR-6500. Probe accuracy and contact conditions must also be considered when assessing the complete measurement.

Choosing your configuration

Specify the surface material, temperature range, target size and measuring distance. Include whether you need an analog output and a contact reference probe.
