Overview

ZDHW-9000 microcomputer fully automatic calorimeter

Product Details

The oxygen bomb automatically rises and falls.
Advanced 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.
The calorimeter supports two ignition methods: ignition wire and cotton thread
Configure a constant temperature water tank for the compressor to observe whether the inner cylinder is short of water
Stainless steel vacuum inner cylinder. The mixing system adopts German imported motors.
Fast testing speed, testing cycle ≤ 8min (rapid method) ≤ 15min (national standard GB/T213-2003).
Thermal capacity stability<0.2% precision<0.1% temperature resolution 0.0001K
This product has excellent performance and reliability even when operating in harsh environments.
Compact structure, beautiful appearance, easy installation and maintenance, low failure rate.
Compact in size, extensively manufactured using molds, with high precision.
The repeatability and reproducibility of the heat generation test are superior to the requirements of the national standard GB/T212-2003.
High 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.
Using the Windows XP operating system, multiple controls are implemented on one machine, with no impact on each other's testing and high software stability.
The data processing function is rich, and users can easily query historical experimental data, current day data, parallel sample data, etc.
Can be connected to an electronic balance to automatically input the weight of the sample.

The microcomputer fully automatic calorimeter is suitable for measuring the calorific value of combustible materials such as coal, coke, petroleum, cement raw materials, bricks, 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.
