Oxygen Bomb Calorimeter ISO 1716 for Testing Calorific Value of Building Materials

• The outer casing of the testing instrument and electrical box is coated with electrostatic powder, resulting in excellent appearance quality, high mechanical strength, corrosion resistance, and rust prevention.
• The calorimeter bomb is made of special stainless steel, offering corrosion resistance and good pressure resistance. The inner cylinder of the calorimeter is a polished metal container with an oval shape, aesthetically pleasing and rust-resistant.
• The oxygen bomb has a simple structure, is easy to operate, has good gas path sealing, and the sealing rubber ring is easy to replace.
• The outer cylinder of the calorimeter is designed with an overflow port, allowing for easy control of the water volume during filling.
• The inner cylinder of the calorimeter uses a bladed electric stirrer, while the outer cylinder uses a submersible electric stirrer, resulting in more uniform and convenient mixing. The instrument uses a fusible cotton thread ignition method.
• The calorimeter operates on a Windows operating system with prompts throughout the process, providing a user-friendly interface that is easy to learn and use. Simply follow the prompts to complete the experiment.
• During the experiment, water is automatically added and drained, eliminating the need for water temperature adjustment. Employing scientifically effective algorithms, the system automatically corrects constants, ensuring high data accuracy, stability, and reliability.
• Control System: The control core employs a self-developed microcontroller board, effectively reducing interference and improving equipment stability. The output terminals utilize new solid-state contactless switching devices.
• During the automatic control process, the detailed product manual can be followed step-by-step. The entire experimental operation is simple and easy to learn.
• The data interface uses RS-232 standard serial communication for synchronous data acquisition. Data is stable, highly reliable, and easy to use.
• User-friendly computer interface for convenient operation. The software control system includes both automatic control and manual debugging modes.
• Software Aspects: The software uses VB.net to develop the interface, supports applications using Dynamic HTML (DHTML) technology, has web application publishing capabilities, and is compatible with WinXP/Win2000.

Building material combustion calorific value testing instruments can be classified according to the function of each part into calorimeter, calorimeter bomb, temperature measuring device, electrical control device, specimen mounting device, etc.

• Calorimeter: The outer casing is powder-coated, giving it a clean and elegant appearance. The calorimeter consists of an outer cylinder and an inner cylinder. The outer cylinder is a double-walled container with an insulated lid, and the space between the inner and outer walls is filled with insulating material.
• Calorimeter Bomb: The calorimeter bomb's lid houses the crucible and electronic ignition device. The lid and all sealing devices can withstand an internal pressure of 21 MPa. The inner wall of the bomb chamber can withstand the erosion of the sample's combustion products.
• Temperature Measurement Device: A temperature measurement device and an electrode ignition device are installed in the upper cover of the calorimeter. During the test, the temperature measurement device measures the temperature of the inner cylinder.
• Electrical Control Device: Uses a computer as the upper computer for control and display. The lower computer uses self-developed circuit boards and temperature modules. The actuators use imported Schneider solid-state relays to control the igniter, stirrer, etc.
