Ludlum 375 digital area monitor hydrogen detector
* (1)LUDLUM 375 DIGITAL AREA MONITOR (P/N: KAC804/45M-AC-C)
This was purchased from a company that went out of business. I was told it was working before removed from its case. When I plugged it in all lights came on and started making beeping noise. Please email me any question you may have.Good Luck!!!
