Please note that postal service is limited to packages less than 2kg in weight.
2019/9/20 New Product Release: TDS modules and TDS Display Board
Have you measured the water quality of your drinking water or aquarium? Just need a small water quality tester (TDS pen). TDS is the most commonly used method for measuring water quality. Holtek’s new TDS Workshop (TDS product development platform) allows you to generate MCU programs in a few steps. With the TDS modules, you can immediately start measuring without code modification. The platform can also display the real-time measurement results and export the data to an excel file. Depending on the MCU used, three TDS modules are provided: 66F0176, 66F0185, and 66F019 (need one of the three). Plus, the TDS Display Board (required) is needed for connecting to the development platform. Awesome? Go for downloading the TDS Workshop.
