1 Scope
This instruction applies to verification or calibration liquid bath temperature stability and uniformity testing.
2 Terms
2.1 bath work area thermostaticbathsworkingspace
That the bath temperature uniformity and stability of the region.
2.2 bath temperature fluctuation thermostaticbathstemperaturevolatility
It refers to the scope of the bath working area within a certain time interval, the temperature change.
2.3 bath temperature uniformity thermostaticbathstemperatureuniformity
Refers to the difference in the working area of the bath temperature and the minimum temperature is the highest.
2.4 work area level thetophorizontalplaneofworkingspace
It refers to the level of the bath working area at the top.
2.5 work area level thebottomhorizontalplaneofworkingspace
It means the lowest level of the bath at the work area.
2.6 Fixed thermometer fixedstandardsforplatinumresistancethermometer

3 Overview
The bath is liquid as a heat transfer medium through the temperature control system and the role of stirring or jet device, to
Set temperature and maintaining the temperature inside the working area stable uniform, mainly used for verification and calibration of various types of thermometers or
Other measuring instruments required temperature equipment. Heat ducts can also refer to this test specification. Bath work area
Is shown in Figure 1.
