641RM-12-LED

641RM-12-LED is a series 641RM air velocity transmitter with remote probe and LED display. It features the same highly accurate heated mass flow sensor as the Series 641, with a remote probe construction. The units 6´ cable which connects the sensing probe with the electronic enclosure allows the enclosure to be mounted where it can be more easily accessed. Typical applications include exhaust stack flow monitoring, HVAC air velocity measurements, clean room ventilation monitoring, air control in drying processes and fan supply and exhaust tracking.
