Large Deluxe Water Bath

Humboldt water baths feature a microprocessor-based digital controller for precise temperature control throughout their temperature range of ambient to 180°F (82°C) at an accuracy of +/-0.1% of input span. The dual digital display simultaneously shows the set point and the process temperature at a glance.

Humboldt water baths are fully insulated to help maintain constant temperatures easily. Models H-1390 and H-1392 can accommodate (12) 4″ diameter or (3) 6″ diameter Marshall specimens at a time. And the model H-1394 can accommodate (16) 4″ and (9) 6″ diameter Marshall specimens at a time. All models include a stainless steel shelf, which supports specimens while allowing 2″ of free circulating water above and below specimens. Models H-1390 and H-1394 also utilize a magnetic stirring bar to induce water flow within the bath and ensure a uniform temperature is maintained. Model H-1392 does not have a magnetic stirring bar. All exposed areas are stainless steel and the front control panel is both water and corrosion resistant.

Microprocessor-based control for precise temperatures throughout the range. Includes magnetic circulator, ensuring constant water temperature, and, a stainless steel shelf, which stands 2″ (51mm) above the bottom of the unit for free circulation of water above and below test samples. Volume is: 14 gallons (53L) and dimensions are 20″ x 20″ x 10″ deep (508 x 508 x 254mm).
