SL7104 Four Channel Data Logger


SL7104 Four Channel Data Logger

The SL7104 data logger has a very flexible combination of inputs that include internal temperature and 4 universal inputs each which means they can be individually configured with the software to accept any combination of the following input types: 

application examples

  • Baking
  • Flow Monitoring
  • Fridge & Freezer Monitoring
  • Cryogenic
  • Weather Environment
  • Process Control
  • Foundry
