A microprocessor-controlled two-channel monitor with automatic solenoid valve on / off switch.
Display size: 4-3/4″ x 3-3/4″ x 7/8″
The S-2A propane monitor / controller features include low current draw, plug in sensors (second sensor optional), display module fault light / alarm and fault light / alarm to indicate a malfunction in either one of the sensors. (Fault indicators show that the module or sensors are not working and may need repair.)
One (1) MS-2 sensor and one (1) SV-1 solenoid valve included.
The system is calibrated at 20% LEL (lower explosive limit) to eliminate most nuisance alarms while allowing enough time to take action.
