Pictured above is a prototype Aqua-Terra-Vita Environmental Temperature Controller (ATV ETC), which is being tested for accuracy by placing the unit's probe into a slurry of ice and water. The display is reading 0.05oC.
The log on the left is displaying the temperature inside my incubator, which contains "Aru" Green Tree Python Eggs. The incubation temperature is controlled by a Herpstat ND proportional thermostat from Spyder Robotics.
The first log line shows the minimum temperature over the past 2,880 minutes to the left and the maximum temperature over the past 2,880 minutes to the right. The variance between the minimum temperature and the maximum temperature is in the middle. The middle of the second log line shows the ideal temperature range and the percent of time the incubator is within the ideal range, while to the left and right is the number of minutes below range and above range, respectively.
