The Lancom 200 from Ametek Land Instruments was developed specifically for oil-fired and coal-fired boiler systems that require periodic monitoring of the sulfuric acid dewpoint temperature to maintain boiler efficiency, prevent corrosion or to evaluate the effectiveness of fuel additives and changes in combustion conditions. The portable monitor assures boiler operaters that the optimum operating temperature is maintained just above the sulfuric acid dewpoint where no sulfuric acid is being formed and combustion efficiency is maximised. The lightweight, easy-to-use instrument is able to obtain a reading in a matter of minutes, is able to capture and store up to 10,000 readings and requires only simple field maintenance.
