SWT-99 Temperature Indicator

Description

The SWT-99X display is designed for the presentation and measurement of temperature readings from up to 8 input channels. Each channel can be individually identified with any measuring unit. The backlit LCD graphical display allows for visualization of the values from all 8 channels simultaneously. A significant advantage is the possibility of viewing the trends in each measuring channel as the graphs for a period of the last 12 seconds to 8 hours. Each device is equipped with electronic relay outputs that can be used to control external devices. There are icons on the screen signalling the status of the outputs. The meter can be configured using a local keyboard or free S-Toolkit software via the RS485 or USB PC communications port.
