High Precision Fully Automatic Plastic Particle Calorimeter High Precision Fully Automatic Plastic Particle Calorimeter Hebi Yinte Instrument & Meter Factory Testing Instrument for Building Material Calorific Value Equipment for Testing Combustion Value of Flame Retardant Materials Calorimeter for Building Material Products Combustion Calorific Value Microcomputer Fully Automatic Building Material Calorimeter

I. Scope of Application

Meets the technical specifications and requirements stipulated in the national standard GB/T14402-2007 "Reaction to Fire Tests for Building Products - Determination of the Heat of Combustion", applicable for testing the combustion calorific value of building materials. The test method specified in this standard is used to determine the gross calorific value of the test product's combustion, regardless of the product's form.  

II. Product Features

1. Automatically controls the outer cylinder water temperature at the set temperature point, ensuring that actual temperature changes do not affect cooling correction, resulting in more accurate measurement results.

2. Automatically adjusts the inner and outer cylinder temperatures, using a unique cooling correction system, water circulation system, and software automatic error compensation system to reduce cooling correction and make measurement results more accurate.

3. Meets the national standard requirement that "at the endpoint, the inner cylinder is about 1K higher than the outer cylinder".

4. The microcomputer calorimeter retains all functions of the microcomputer system, can run general software for other tasks, and simultaneously starts the calorimeter measurement system to automatically calibrate the energy equivalent (heat capacity) of the calorimetric system and measure the calorific value.

5. The inner cylinder of the microcomputer calorimeter uses an electric stirrer with blade paddles, and the outer cylinder uses a submersible electric stirrer, making stirring more uniform and convenient. The instrument uses a fuse-type cotton thread ignition method.

6. The microcomputer calorimeter operates on Windows XP and above operating systems, with full Chinese prompts, human-computer interaction, easy to learn and use; simply follow the prompts to complete the test.
