Overview

1. Oxygen bomb automatic lifting, automatic inner bucket constant water volume, automatic control of inner bucket water temperature regulation, and automatic completion of experiments

Product Details

1Oxygen bomb automatic lifting, automatic inner bucket constant water volume, automatic control of inner bucket water temperature regulation, automatic completion of experiments.

2Advanced compressor refrigeration technology, completely unaffected by environmental temperature changes, ensures that the temperature difference between the inner and outer cylinders of the instrument meets national standards. Can work continuously for a long time.

3The calorimeter supports two ignition methods: ignition wire and cotton thread

4Configure compressor constant temperature water tank,Observe whether the inner cylinder is short of water

5Stainless steel vacuum inner cylinder. The mixing system adopts German imported motors.

6Fast testing speed and testing cycle≤8min(Quick method)≤15min(national standardGB/T213-2003).

7Thermal capacity stability<0.2%precision<0.1%temperature resolution0.0001K

8This product has excellent performance and reliability even when operating in harsh environments.

9Compact structure, beautiful appearance, easy installation and maintenance, low failure rate.

10Compact in size, extensively manufactured using molds, with high precision.

11The repeatability and reproducibility of the heat generation test are superior to the national standardGB/T212-2003The requirements.

12High degree of automation, automatic utilization of the water volume in the built-in fixed container, automatic control of the temperature difference between the inner and outer buckets of the instrument, and automatic completion of the entire experimental process. Can be connected to an electronic balance.

13useWindowsXPThe operating system enables multiple controls on one machine, with no impact on each other's testing and high software stability.

14The data processing function is rich, and users can easily query historical experimental data, current day data, parallel sample data, etc.

15. Can be connected to an electronic balance to automatically input the weight of the sample

The high-precision microcomputer fully automatic calorimeter is suitable for measuring the calorific value of combustible materials such as coal, coke, petroleum, cement raw materials, bricks, biomass fuels, and other solid or liquid materials in industries such as power, coal, metallurgy, petrochemicals, quality inspection, environmental protection, cement, papermaking, geological exploration, and research institutes. It meets the requirements of the national standard GB/T213-2008 "Method for Determining the Calorific Value of Coal". The high-precision microcomputer fully automatic calorimeter is the main instrument in the coal quality laboratory.
