HUMBOLDT Testing Equipment for Construction Materials Humboldt Water Baths H-1390, H1392, H-1394 H-1394 H-1390 Water Baths with Microprocessor-based Temperature Control • Auto-tuning is fast & effortless • Dual, digital display simultaneously shows set point and process temperature • Ramp-to-set point handles critical temperature processes smoothly • Set point range limiting protects process and equipment • Percent power limit protects components from stress • Rapid cycling provides fast system response • Operator lockout guards against unwanted changes • All exposed parts are stainless steel. Front panel is water and corrosion resistant. Humboldt waterbaths are a perfect match for Marshall and Superpave test applications and meet ASTM D1559, D5581 and D4867. 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.
