PTX Series 1 mg Touch Screen Precision Balance
The PTX Series is built around an IoT-enabled 5-inch colour TFT integrated touch screen. A high-performance single-chip microprocessor, a high-speed CPU and a dedicated ASIC chip work with a high-precision electromagnetic force (EMFC) sensor to deliver accurate, stable weighing results. The housing is precision-cast from environmentally friendly ABS and the interface switches between Chinese and English with a single tap. A high-efficiency die-cast aluminium alloy base keeps the load-bearing structure rigid and stable, the fully transparent glass windshield keeps the sample clearly visible, and both the deck plate and the weighing pan are made of stainless steel. Weighing modes include weighing, parts counting, percentage weighing, unit conversion, time setting and density determination.
