LDP ECHOLINE® Series Low Pressure Monitor -

LDP ECHOLINE® was designed in cooperation with a leading semiconductor manufacturer to provide state-of-the-art low pressure monitoring of gas cabinet exhaust systems. “ECHO” (Electronic Circuit Health Output) diagnostics alert the user to loss of external power or internal electronics failure. LDP ECHOLINE’s® unique Maintenance Mode option prevents false trips during ventilation system balancing.
LDP ECHOLINE® Corrosive Media incorporates stainless steel sensor technology into ECHOLINE’s® LDP Series allowing for low pressure monitoring of corrosive media systems while maintaining ECHOLINE’s® display, switching, analog output, and “ECHO” functions. This improvement allows the unit to be used in applications that previously could not be monitored with the ECHOLINE® LDP series.
