This Digital Temperature and Humidity Meter continuously monitors and displays readings numerically and graphically. The internal sensor makes these ideal for use in hoods, stores, cleanrooms, incubators, and drying or environmental chambers. A week's worth of data is kept safe and the memory cannot be cleared, only overwritten by the next day's measurements. 

• Easily switch between °F/°C and 12/24-hour time formats.

• Maintain data integrity—historical data cannot be cleared, only overwritten.

• Scroll through temperature and humidity data for the past seven days.
