The TV-4510 monitors Temperatures from -30 to +50°C (-22°F to +122°F) using a built-in sensor, and has a connection for one of our range of thermistor probes for monitoring from -40 to +125°C (-40°F to +257°F). As a dual-channel logger, this versatile unit is ideal for comparison of, for example, ambient and process temperatures. A display provides a visual readout.
