Electronic calculators for heat meters

Big and readable 8-position display with additional 4-position indicator, many intuitive symbols and units for the displayed values
Two buttons that make operation of the calculator much easier (mechanical or capacitive version)
Possibility of individual configuration of the calculator according to particular requirements, configuration of parameters, functions, communication, type and range of data displayed on LCD through a dedicated program (on PC)
Possibility of manual configuration of some parameters of the calculator using the buttons
Possibility of mounting (without legalisation infringement) two independent communication modules and a selection of communication protocols
