The Humboldt Hydrometer Water Bath is designed to provide a 68°F (20°C) ambient temperature throughout the unit by using a microprocessor-based temperature control with integral heater and chiller. The control processor in the H-4239A provides a consistant bath temperature of 68°F (20°C) accurate to within 0.1% of input span ±1°F. 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 bath. While the Humboldt Hydrometer Jar Water Bath can be used for many uses within labs, it was designed specifically for use in providing a consistent temperature bath for storing hydrometer jars in accordance with ASTM D422, AASHTO T88 and UNE 103.102 to determine the particle size distribution of very fine materials, such as silt and clay. The H-4239A can accommodate (8) 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.
The H-4239A Water bath provides:
• fast & effortless auto-tuning of temperatures;
• simultaneously shows the set-point and process temperature on its dual-digital display
• smoothly handles critical temperature processes with ramp-to-setpoint;
• processes and equipment are protected by set-point range limiting;
• percent power limit protects components from stress;
• rapid cycling provides fast system response;
• operator lockout guards against unwanted changes, and
• all exposed parts are stainless steel, and the front panel is water and corrosion resistant.
