The ME-SP331 provides the most flexible solution for thermometer integration requirements from families, offices, PC rooms, laboratories and vehicles. With the help of an external thermo sensor and 7-segment LEDs, ME-SP331 is capable of displaying the measured temperature in either °C or °F. A reserved header on the rear of thermometer allows you to connect an extra external thermo probe (not offered) so that you can extend the application range to another harsh application environment . With an extra external thermo probe connected, you can monitor and compare the temperature readings in two different application environment in one thermometer by setting K3 and K4 of the DIP switch on the rear of thermometer.

With the same 7-segment LEDs that are integrated in panel meter series, ME-SP331 is still featured with wide viewing angle and clear contrast. Its self adaption ability to the ambient brightness helps reduce the power consumption that is very suitable for many applications.
