The traditional refrigerant slider has now a new electronic PT Chart option for refrigeration and HVAC professionals. Honeywell offers a colorful display in which users can select a refrigerant and get all of the data they need to perform their tasks in the field, from P-T data to superheat and subcool calculation to set a control (average of dew and bubble point are included). Physical properties, environmental and safety information, as well as the MSDS (Material Safety Data Sheet) are included for the main refrigerants used today in the field.
