HVAC engineers and technicians require instruments for both laboratorywork and fieldwork. Precision is more essential in the laboratory, whereresearch and development are undertaken, than in the field, where acceptanceand adjustment tests are conducted. This chapter describes the characteristicsand uses of some of these instruments.
