How stable is the temperature in a Whitley Workstation?
TEMPERATURE STABILITY IN A WHITLEY WORKSTATION The development brief for the Whitley Workstation product development team required that temperature variation within the working area of the workstation would be maintained within a temperature band of ± 0.5°C. Whilst the temperature profile across the workstation has been determined to be within ± 0.5°C, the operating temperature is controlled by measuring the temperature of the return path atmosphere before the heater. This ensures that the temperature measuring probe is positioned in an area inaccessible to the user and therefore not prone to accidental damage. DWS In-House Test Procedure 1. The Whitley Workstation is powered up and the temperature controller is set to 36.5°C. The instrument is allowed to stabilise for 4 hours. 2. A NAMAS-traceable, calibrated mercury/glass thermometer placed in a bottle of glycerol is positioned centrally on the top shelf of the workstation, 50 mm from the front edge. The workstation is left to stabil
