![]() |
°C / °F Switchable: Indicates that readings can be displayed in either degrees Celsius or degrees Fahrenheit. |
![]() |
Min / Max Feature: Includes a feature allowing you to quickly display the maximum and minimum values measured during a specified period of time. |
![]() |
Dew Point: Indicates devices that calculate and display the air temperature at which, under current barometric pressure, the water vapor currently in the air would condense into water or dew (or reach 100% humidity). |
![]() |
Measures Relative Humidity: Indicates devices that measure relative humidity, which is the amount of water vapor in the air at a specific temperature compared to the maximum water vapor that the air is able to hold without it condensing at a given temperature. |
![]() |
Data Logging-Capable: Shown when a device has the ability not only to display readings, but to record and store multiple readings at regular increments over time. |
![]() |
Alarm: Includes a feature that will alert you via visual and/or audible cues (or, in some cases, email or texts) when a reading is outside user-specified limits for safety or desirability. |
![]() |
Includes LCD Display: Shown when a logger includes a visual LCD display of data readings on the logger itself. |
![]() |
Water-Resistant Rated: Indicates that a product has been tested for protection against the ingress of water into the equipment. See the product specification table for the actual test rating and see our IP Table. |
![]() |
USB-Enabled: Includes a USB port for easy downloading of stored data to your computer. |
![]() |
Wireless-Ready: Shown when a thermometer or logger has wireless data broadcast capability. |
![]() |
NIST-Traceable Certificate: Indicates either the inclusion or availability of a certificate showing the traceability of a device to standards of accuracy set by the National Institute of Standards and Technology (see NIST.gov). |
