The NEW Humboldt Hydrometer Water Bath uses a microprocessor-based temperature control with integral heater and chiller to provide a constant, accurate 68�F (20�C) ambient temperature throughout the unit. The temperature range can be set between 50�F (10�C) and 120�F (49�C).
The H-4239A Water Bath is fully-insulated and includes a circulating pump which ensures a constant water temperature throughout. While the unit has many laboratory uses, it was specifically designed to provide a consistent temperature bath for storing hydrometer jars in accordance with ASTM D422, AASHTO T88 and UNE 103.102. The H-4239A can accommodate eight hydrometer jars at a time. All models include a stainless steel shelf which supports specimens while allowing 2" of free circulating water above and below specimens.
