APP Software Control

We keep upgrading APP software to better user-experience.
App software connects machine by Wifi, once you open your machine, then open your WLAN on mobile phone or pad, you can find “Santoker R500”, then click it to connect your device.
App software operation is much more popular than touch screen operation. Customers don’t have to stay with machine while roasting, the mobile phone or pad like a remote control, they can control the roast anywhere Wifi overed.
Our App software could save any of your roasting profile automatically, you can overwrite, share and export roasting profiles.

Hot Air Pressure Gauge

Controlling airflow is very important during roast. Normally,
for WS-500Master, we control airflow is only by manual damper or Electric damper on APP.
But once you forget to clean up the exhaust pipe and exhaust fan motor in time, the dust and chaff may block the pipe or motor, or if you meet the bad weather (like strong wind, heavy rain etc.), you may not get exact pressure value by manual damper or Electric damper.
Then the hot air pressure gauge can help you get the real airflow pressure value in any condition, that makes your roast more precisely.
