TIF 3310/3320 takes differential temperature readings with dual type-K thermocouple probes and non-contact surface temperatures using the IR thermometer probe. TIF 3110 is an IR thermometer/psychrometer that provides speedy checks on indoor air quality. TIF 3220 measures air speed and temperature, enabling airflow measurements of targeted areas at various air returns and vents.
