Koehler
K88800 Automatic Calorimeter
Test Method
Heat of combustion is determined in this test method by burning a weighted sample in an oxygen bomb calorimeter under controlled conditions. The heat of combustion is computed from temperature observations before, during and after combustion with proper allowances for thermochemical and heat transfer corrections. Either isothermal or adiabatic calorimeter jackets can be used.
Features and Benefits
• Compact, integrated modular design for convenient operation
• Conforms to DIN 51900, ASTM 240 D, ISO 1928, BSI and other specifications
• Automatic sample ignition
• Three Automatic water handling system includes tempering, filling and emptying of calorimeter inner vessel
• Automatic decomposition vessel identification
• Up to eight measurement cells can be controlled by a single PC, using a multi-serial plug-in card PCI 8.2 (accessory)
• Automatic oxygen filling of decomposition vessel
K88800 Automatic Calorimeter
The automatic calorimeter is the latest system for determining gross calorific values of liquids and solid fuels. A higher level of automation with extremely simple handling characterizes this device.
In addition to the Isoperibolic measurement procedure, a Dynamic (reduced-time) mode is also available for the user. Different working temperatures can be selected for both procedures based on the temperature of the connected water.
To provide a supply of cooling water, the calorimeter can be connected to a standard thermostat or an appropriate permanently installed water connection, with a connection valve. The unit is equipped with a very convenient operating panel through which operation of the device takes place. The graphical display with active backlighting displays the appropriate status messages. The temporal course of a measurement that has been started and all current parameters of the weighed in sample can be constantly monitored and are arranged to be clearly visible.
Connections for analysis scale, printer, and sample rack for identifying and managing samples are already integrated into the basic device. The network connection and the special configuration for data exchange can be implemented at any time with LIMS.
In combination with special halogen-resistant decomposition vessels quantitative decompositions can be performed to determine halogen and sulfur content.
