Internal Product Review

  • ‘‘The 084B8030 excels in tight installation spaces and the 3-digit LED display is surprisingly readable even in poor lighting conditions. The MODBUS integration works flawlessly with existing building management systems right out of the box. However, the -60°C lower range limit may not be sufficient for some freezer applications.’’
