IncuTrol/2 Temperature Regulator for BOD Incubation

The Model 2597A IncuTrol®/2 Regulator is a self-regulating temperature controller designed to convert any manually defrosted refrigerator into an incubator. The instrument is used with the Hach Model 2173 BOD Apparatus for incubating wastewater samples during the five-day biochemical oxygen demand test. When placed in a working refrigerator, it will maintain a constant temperature within the range of 5° to 45°C. The instrument can also be used to control temperature environments in other sealed chambers where the required temperatures are above room temperatures but do not exceed 45°C. The temperature is maintained by means of temperature-controlled electronic gates which appropriately apply or interrupt AC power to the heater and refrigeration units. The fan runs continuously to ensure an even temperature throughout the compartment. A two-inch dial thermometer mounted on the front panel provides a convenient, easy-to-read temperature indication. The temperature is set with a screwdriver adjustment control, also located on the front panel. Power receptacles on the rear panel of the regulator allow two BOD respirometers to operate simultaneously. IncuTrol/2 Regulators can be purchased for either 115 or 220 volt operation. They cannot be converted because the heater and motor differ between the two instruments. The power required is approximately 120 watts.
