Excellent Honewell RA890 tester which is vital for older flame fired units.

Receipt of this unit made the root cause analysis simple, as the flame signal strength was not sufficient to keep the F relay on. The tester allowed me to test the RA890 and see that the F relay was in good working order.Read full review...
