Check the listing for details. Vintage Heathkit Digital Rain Gauge ID-1790. Condition: Used. Listed at 69.99 USD. This unit seems to be working and powers on. Other than that I don't have much info on it. I pulled it from a house where they had a whole Heath kit weather stations set up and was working. I try to be competitive on pricing so if you can show me the same item on eBay at a cheaper price, I can work on price matching or beating it. All items ship out the next day except weekends. Let me know if you have any questions or need additional photos. I offer combined shipping. Thanks
