Testo Manual Smoke Pump (0554 0307) The Testo Manual Smoke Pump is a heavy-duty instrument for accurately measuring the smoke content in oil burner flue gases, taking the guesswork out of setting a burner for optimal efficiency. Flue gas is drawn through the pump, staining the supplied filter paper, and the result is compared against an included smoke scale for a precise reading. It's compatible with Testo's range of flue gas analysers for determining the smoke number in oil burners, and is TÜV approved, corresponding to DIN 51402 and ASTM D 2156. The robust construction is built for long-term use in demanding site conditions. It's supplied with a smoke scale, filter paper (pack of 40) and lubricant. Please check with us whether the probe cone is included with this specific kit, or needs to be ordered separately. Key Features &
