So the two probe is limited by the wire connected between them. The singles are not, so if your liquid port is say five feet away from suction like on a large Lennox package unit u would need two...

Anyone have issues with the testo 550 temp clamps not being accurate in pac
kage units seems like they not well insulated from airflow
