The Model L452 is a low cost, simple to use, two-channel data logger. It records DC voltage, DC current, pulses and events. Its two input channels allow the user to connect to various types of sensors in order to record data such as pressure, temperature, flow, humidity and more. This logger can also be used to record events such as machine run time. Each channel’s real-time measurement is displayed on the LCD screen. The L452 communicates via USB or Bluetooth for configuration and data transfer to a PC using the free DataView software included with the unit. The logger can also be configured using its front panel with a very simple user interface.
