This Lab-Line Aquabath Model 18202 14 liter Digital Waterbath is in used condition and was removed from a working environment. Please note that this item is one of our older listings and we are planning to retest and reshoot photos. Some of the photos included with original listing were located in the description and as a result could not be transferred. Please see screenshot of the description page from the original listing. We will be happy to provide additional information as well as new photos upon request. Please feel free to contact us with any questions. Chamber dimensions: 12.7" x 11.6" x 5" d Bath temperature is read from a glass thermometer (not supplied) on Standard Aquabaths and from an LED readout on Digital Aquabaths. Standard Aquabaths are controlled by an adjustable hydraulic thermostat. A second independent hi-limit thermostat assumes control of bath temperatures should the control thermostat fail. Temperature is maintained even if the bath accidentally runs dry, thereby eliminating heater burn out. Individual pilot lights indicate which thermostat presently controls temperature. Digital Aquabaths feature digital set temperature. Each Aquabath can be used as a boiling bath with the addition of the Plexiglas gable cover (included).
