Measure Temperatures With Apple
A temperature measuring and
control system is now available as a peripheral to the Apple II
The device accurately measures temperatures between
-60 and + 105 degrees Celsius. Changes of temperature as small as
1/100th of a degree may be detected. The system, produced by American
Data Cable, uses a hand-held probe the size of a marking pen and
attaches to the Apple II computer by a 6-foot cable. The system
software is on a DOS 3.3-compatible, 5.25-inch diskette.
The system, called the Nth Degree, displays
temperature readings in either Celsius, Farenheit or Kelvin. An
optional program displays or can print out a continuous record of
temperature changes in a "strip chart" format.
The Nth Degree digital temperature
probe for Apple II.
Accuracies of .01 degree may be obtained, and the
probe can be re-calibrated for maximum accuracy over any temperature
range. In addition, the system may be programmed for alarms and set
The probe can measure reaction rates and
temperatures of reactants, and can monitor heating and cooling
apparatus. The disk accepts up to 16 years' worth of temperature
readings (taken one time an hour) or can store continuous samplings of
temperatures taken once a second for 36 hours.
As many as 256 probes may be attached to one system.
Temperature readings are made simply by placing the lightweight probe
against the surface to be measured. When not in contact with a specific
material, the probe measures the temperature of the air.
The model 551A probe with software, Apple II
interface adapter and user's manual sells for $129.
