The TESTO 0554 3100 is an infrared thermal printer designed to pair exclusively with the Testo 310 Combustion Analyzer. It receives data wirelessly via infrared and produces printed records of combustion analysis readings directly in the field. Combustion technicians rely on printed reports for documentation, compliance records, and customer sign-off. The unit runs on four AA batteries, making it fully portable with no external power needed on the job. At 192 grams without batteries, it is light enough to carry alongside the analyzer during service calls on residential or light commercial heating systems.
This printer is intended for use with the Testo 310 Combustion Analyzer only. It is suited for HVAC and combustion service technicians who perform flue gas analysis on gas-fired or oil-fired heating equipment. The infrared data transfer eliminates cable connections between the analyzer and the printer, keeping the workflow clean during boiler and furnace tune-ups or emissions checks.
Designed for use with the Testo 310 Combustion Analyzer only. Not intended for use with other Testo analyzer models or third-party combustion analyzers.
This printer is a field accessory installed and operated by licensed HVAC or combustion service technicians. Before pairing with the Testo 310, ensure fresh AA batteries are installed and the analyzer is powered on with IR transmission enabled. No hardwiring or electrical connection to building systems is required. Store the unit within the rated storage temperature range of -20 to 50 degrees C when not in use.
