HD-549 - Temperature and Humidity

HD-549 Model is a floor-style environmental test chamber with temperature and humidity functionality. 

STRUCTURE. The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction . The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. Between the two layers is highly-efficient, low k-factor, thermal insulation. This chamber is built to last for many years.

CIRCULATION SYSTEM. Air circulation is crucial for environmental testing. The HD-549 Test Chamber has a proprietary baffle and fan design combination. This optimizes temperature and humidity conditions within the workspace. 

HEATING SYSTEM. HD test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.

HUMIDITY SYSTEM. The humidity system has a standard range between 20% and 95%. To extend your humidity range, see the optional features section. 

COOLING SYSTEM. The cooling system in the is HD-549 consists of a self-contained, compact, single-stage, mechanical refrigeration system with an air-cooled condenser. An optional water cooling condenser is available. 

INSTRUMENTATION.  HD Series Test Chambers have incorporated AESONE CONNECT creating a robust connected device for a standard and uniform interface making operation easier. See Instrumentation Tab below.
