An Inexpensive Digital Temperature Integrator |
|
| Abstract: | An inexpensive thermistor-type digital temperature integrator for temperatures from 40 to 110°F is described. The baseline temperature above which integration occurs is adjustable from 40 to 60°F. The digital counter readout is in units of day-°F with 0.1 day-°F resolution and has an accuracy within ±2 percent of the indicated value. |
