WT331xx Hazardous-area Weighing Terminal

WT331xx is a high quality n-type hazardous-area weighing terminal from WPTEC. Which is suitable for use in hazardous environments in Zone 2/22, thanks to the complete improvement of the WT331 in terms of housing, wiring, introduction, insulation and dielectric strength, electrical clearance, etc.
The WT331xx can be used in a wide range of industrial applications such as paint and ink, pesticides and fertilisers, pharmaceuticals, tobacco, flavours and fragrances.
Reliable performance, practical interfaces, easy calibration, convenient parameterisation and system backup make it easy and efficient to display, control, check and sort and monitor the flow in hazardous areas.
