Customer complained about high humidity. Used my srh2 and got readings from 45% to 60% in the same room. It's a commercial office about 3000-4000 sq feet. Is the instrument off or can humidity vary that much 100 feet apart? It was just hit and miss!!! I could take the RH it be 49% walk out, come back 30 min later to the same spot and it be 55%.
