Hygrometers are used to measure humidity and vapor in air, and soil. These days, compact hygrometers are in demand because they are extremely easy to use and are best suited for field applications. These hygrometers show relative humidity and air temperature with precision. These devices are capable of recording T1 and T2 differential with the help of TP890 or optional probe. Some hygrometers have a unique sensor cap that keeps the hygrometer safe during storage. Some advanced hygrometers have special features such as auto power off, data hold, average reading along with minimum and maximum batteries. Hygro Thermometer clocks put together reading for time, humidity and temperature. These clocks display time in 12/24 time format. These hygro thermometer clocks can measure temperature in the range 14 to 140 Deg F, -10 to 60 Deg C.
