The longitude (abbreviation: Long., Î», or lambda) of a point on the Earth's surface is the angle east or west from a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses (often improperly called great circles), which converge at the north and south poles.
Use the dual thermometers to calculate relative humidity. Fisher Scientific Mason's Hygrometer has one dry thermometer and one wet thermometer which provide temperature readings for determining the relative humidity.
With these factors in mind, we created the IncuThermâ¢ series digital thermometer/hygrometers. The IncuTherm Plusâ¢ is able to accurately measure and display the temperature and relative humidity at the same time which can be displayed in both Fahrenheit or Celsius. The probe is placed inside the incubator. This allows the IncuTherm Plusâ¢ to measure temperature and humidity on the inside of your incubator and display it on the outside. The built-in high and low memory stores the highest and lowest temperature and humidity readings since the last memory reset. This helps you ensure ideal conditions for a successful hatch.
