A kindergarten teacher is responsible for planning the curriculum for each day and for the collective school year. Teachers must allow the children to observe an activity while also giving them the opportunity to ask questions and look for the answers. Instructions need to be very precise yet easy to understand.
The CS220 is a thermocouple that measures the temperature of a surface by direct contact. SI-111 Infrared Radiometer with Standard Field of View. The SI-111, manufactured by Apogee, is a precision infrared radiometer that determines the surface temperature of an object without physical contact.
This is the temperature required at the core of the material, not at the material surfaces. The relationship between core temperature and surface temperature will need to be determined. Sheet surface temperature will directly correspond to material gage. For example, letâs use 0.250-in. high-density polyethylene (HDPE), which requires a core temperature of approximately 280Â°F for optimal forming.
