The Digital Manometer Monitor uses an integrated digital pressure transducer to monitor exhaust system negative pressure. The monitor indicates through both a segment display and LED's. The segment display is green and operates to + 0.01" w.g. sensitivity. The LED's indicate acceptable pressure (green), caution or near alarm points to within 0.005" w.g. (yellow) or alarm condition (red).
IT IS RECOMMENDED THAT THE MONITOR BE CALIBRATED ANNUALLY.
