RFHTT Modulating Temperature Recorder

This unit is a dual recording thermometer designed to sense and record temperature from two separate ocations simultaneously on a single chart. The case contains two pen mechanisms with individual thermal sensing elements. The pens operate on 1/12 revolution of the chart, for example 2 hours per 24 hour rotation to prevent possible interference when both sensed termperatures happen to coincide. Flush or wall mount available (brackets supplied). Available in 12 ranges from -30ºF to 1100ºF.

Overview / Design Principle:
This unit is a dual recording thermometer designed to sense and record temperature from two separate ocations simultaneously on a single chart. The case contains two pen mechanisms with individual thermal sensing elements. The pens operate on 1/12 revolution of the chart, for example 2 hours per 24 hour rotation to prevent possible interference when both sensed termperatures happen to coincide. Flush or wall mount available (brackets supplied). Available in 12 ranges from -30ºF to 1100ºF.
Operation:
This unit consists of a chart drive either electrically driven or spring wound. This chart drive rotates a 10" chart on which two independent pens mark temperature. The mechanism pens function as a result of the Piston Pak expanding or contracting due to termperature change.
