Introduction

1.1 Controller Cover

The controller is mounted on top of a specially designed refrigerator. The sample line passes through the top of the refrigerator and into the refrigerated compartment where the sample containter(s) are located. The compartment is surrounded by rigid foam insulation and utilizes a 120 CFM condenser fan. An optional controller cover locks and protects the controller from damage and unauthorized users.

Sample temperature is controlled by an adjustable air sensing thermostat maintaining samples at 4 °C (39 °F) in ambients up to 50 °C (120 °F). The unit has a magnetic door seal and does not require rear ventilation. The refrigerator interior is food grade plastic and the exterior is coated galvanized steel (304 stainless steel is optional). As a further barrier against corrosion, the refrigeration components and copper plumbing are treated with phenolic resin coating.

1.2 Front Panel

The front panel (Figure 1) of the sampler consists of the keypad, liquid crystal display, and the internal case humidity indicator.
