the document does not show info on the sensor, only for extra communications addons, right? I need to find who makes those sensors.... thanks,
How many do you need? The chance of buying "a few" of those OEM parts is microscopic, if not zero.
The fact that Hanna and Milwaukee sell the same basic item in different boxes and application ranges suggest that it is a generic item from another manufacturer, custom programmed and labeled.
I have no doubt that they contract for thousands (if not tens of thousands) of units per production run.
Even if you found the company that makes it, you would not be able to buy, ship and pay import duty for less that the quoted price.
Buy a used one on eBay: https://www.ebay.com/itm/255623540739
I need about 50units/month!! to start.... this is why I really need to find a good deal..
Have you asked Milwaukee and Hanna where they sourced their products?
I already ask other manufactures, they all are very jealous on this info...
It shows that they got the sensor you want out of a Milwaukee MA871 refractometer. They implied that you would have to buy a whole Milwaukee MA871 refractometer for about $100 to duplicate their work.
I checked AliBaba.com and could find no source of raw digital refractometer sensors. There must not be much of a market in refractometer parts, just whole refractometers.
If you need a custom refractometer of a type that is not commercially available you may need to contract a manufacturer to make them for you. Here is one choice in China:
Zhejiang Lohand Environment Technology Co., Ltd.
Address:2F,Building 7,No.63, Jiuhuan Rd, Jiubao Town, Jianggan District, Hangzhou ZheJiang China
Postal code:310019
