The Vision Temperature Recorder (VTR) records, saves, and prints up to 290 temperature readings at predefined intervals. The VTR produces an alarm whenever the temperature goes above or below a defined range. The alarm can be produced immediately when the temperature goes out of the defined range, or after the temperature remains out of range for a certain period of time. The VTR provides several printing options, including the ability to send data to an external PC. The VTR can also send alarms to an external device via a relay contact. The VTR can monitor, log, and print temperatures of -40°C to +130°C (-40°F to +266°F), +\- 1°.
