Abstract
Abstract A portable temperature data recorder for temporarily storing plural sets of temperature data representative of temperatures at a single location or at different locations, and automatically transferring the stored temperature data to a data processing unit. The portable recorder has a connector for connection thereof to the data processing unit. The portable recorder may further have a connector for connection thereof to a stationary temperature detector or thermometer installed at each measurement location. Alternatively, the temperature recorder incorporate a temperature detector for measuring the temperatures at the measurement locations. A clock circuit may be provided in the portable recorder, so that the temperature data may be stored together with measurement time data. The temperature detector may be a radiation thermometer provided at the measurement location, or built in the portable recorder.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
A portable temperature data recorder for storing in a stationary data processing unit temperature data measured by a stationary temperature detector disposed at a measurement location, or by stationary temperature detectors disposed at different measurement locations, comprising: first connector means coacting with said data processing unit for temporarily connecting the temperature data recorder selectively to said stationary temperature detector at said single measurement location, or to said stationary temperature detectors at said different measurement locations, respectively, and said connector means for connecting the temperature data recorder to said stationary data processing unit; and memory means in said data processing unit for storing in succession plural sets of temperature data representative of temperatures measured by said stationary temperature detector or detectors, together with corresponding sets of measurement location data representative of said measurement locations, while the temperature data recorder is connected to said stationary temperature detector or detectors through said connector means, said plural sets of temperature data and the corresponding sets of measurement location data being transferred from said memory means directly into said data processing unit while the temperature data recorder is connected to the data processing unit through said connector means.
Claim 2
Dependent Claim
193 words
A portable temperature data recorder for storing in a stationary data processing unit temperature data measured by a stationary temperature detector disposed at a measurement location, or by stationary temperature detectors disposed at different measurement locations, comprising: first connector means coacting with said data processing unit for temporarily connecting the temperature data recorder selectively to said stationary temperature detector at said single measurement location, or to said stationary temperature detectors at said different measurement locations, respectively, and said connector means for connecting the temperature data recorder to said stationary data processing unit; and memory means in said data processing unit for storing in succession plural sets of temperature data representative of temperatures measured by said stationary temperature detector or detectors, together with corresponding sets of measurement location data representative of said measurement locations, while the temperature data recorder is connected to said stationary temperature detector or detectors through said connector means, said plural sets of temperature data and the corresponding sets of measurement location data being transferred from said memory means directly into said data processing unit while the temperature data recorder is connected to the data processing unit through said connector means.
