PORTABLE EQUIPMENT FOR MONITORING AND CONTROLLING THE LEVEL OF OXYGEN IN REFLOW OVEN ATMOSPHERE

摘要

The present invention describes a portable device for monitoring and controlling the level of residual oxygen in reflow oven atmosphere (1). This referred equipment is able to determine the quality of the atmosphere of a reflow oven, using parameters predetermined by the user. Therefore, the equipment performs the monitoring of the reflow oven atmosphere (1) controlling the level of residual oxygen of the reflow oven (1) by increasing or decreasing of the feed flow rate of nitrogen by the control that the microcontroller exerts over the proportional valve of nitrogen flow control (9), by opening or closing the valves to kept such predetermined values.
