Excellent Original!
I have owned a Zeal for the past twenty years.(They are used in textile mills to measure relative-humidity).I was not sure it it will have the same quality now, but I was surprised!Good quality original!The extra wicks and the printed table/chart were also included.I am going to order another one!
