Microcomputer automatic calorimeter

The FRL-3000 calorimeter uses a Windows operating system for real-time control and analysis of the entire process, with simple operation, reasonable structure, and accurate results. It complies with the provisions of the constant temperature calorimeter method in GB/T213-1996 "Method for Determining the Calorific Value of Coal". This instrument is mainly used for determining the calorific value of solid and liquid combustibles, such as coal, petroleum, food, wood, etc. It is particularly suitable for measuring the calorific value of coal and can directly obtain the high-level calorific value of the sample and the low-level calorific value of the received base.

（1） Main features of the FRL-3000 microcomputer calorimeter
1. Automatic control of the entire process, automatic adjustment of water temperature, automatic addition of water and drainage, automatic compensation and weighing, automatic mixing, ignition, display of instrument status, sound prompts, fault alarm prompts, and automatic printing of results.
2. The testing speed is fast, the results are accurate, and it has the function of converting joules and calories.
3. Reasonable structure, excellent production, and lightweight and convenient flip cover.
4. It can control 1-2 constant temperature buckets simultaneously, with self diagnosis, short circuit protection function, automatic conversion of high and low heat generation, data query, recalculation, printing reports and other functions.
