PKWS-D type intelligent temperature and humidity transmitterDetailed product description：

Main functions and features

The PKWS-D intelligent temperature and humidity transmitter adopts Swiss imported digital sensors, which have reliable performance, high accuracy, small annual drift, and fast response speed. Suitable for temperature and humidity measurement in communication rooms, offices, factories, workshops, warehouses, hospitals, archives, museums, HVAC systems, building automation and other environments. The instrument is wall mounted and easy to install. The large LCD screen displays both temperature and humidity simultaneously. Its output is in 485 bus mode; The communication protocol is MODBUS-RTU, which facilitates the formation of a temperature and humidity measurement and control network. Optional 4-20mA/0-5V/0-10V signal transmission output.
