The UT-D07A is a BlueTooth adapter for the UT-71, UT-181 and UT-171 DMMs, and it costs around £20, if you shop around on eBay and AliExpress.
However, the UT-D07A is not much cop apparently… or rather the (iOS) software crashes regularly, there’s no Windows software to speak of, and basically, it’s probably not worth the cash… That said, it could be a useful addition, if you need to see graphical data. However, it is worth noting that as there is no Mac or Windows support, the ability to use that data, apart from obtaining pretty graphs from iPhone/iPad screenshots, may be rather limited
