Tekneka 440 is a mini temperature and humidity meter with a measurement range of -20 to 60°C and 0 to 100%RH. Larger digital digits on the 2-inch display screen will make it easier to see, and it has a number of features like Bluetooth connectivity, HOLD, LCD backlight, MIN/MAX, and more. The “Meterbox Pro” mobile application allows users to record values, view them in real-time, and export data. The 400 series features Bluetooth connectivity to do this. The transition can also be eased by computing the temperature difference between dry and wet bulbs. Each project can be stored on a user’s smartphone, which also allows for live monitoring via graphical representation.
