The document describes two thermo-hygrometers, models 103-CTH and 411-CTH. Both devices measure temperature from -50 to 70 degrees Celsius, humidity from 10 to 99% RH, and keep maximum and minimum readings and time with an alarm clock. The 103-CTH has a larger display and measures temperature in Fahrenheit and Celsius, while the 411-CTH also displays comfort levels and measures humidity up to 90%. Both devices require AAA batteries and are distributed by Monarch Controls in Bangalore, India.
