Microcomputer Based Fully Automatic Calorimeter HM-LR4

Product Introduction

This instrument is suitable for measuring the calorific value of solid or liquid combustibles such as coal, petroleum, cement raw materials, grains, feed, etc. in industries or departments such as electricity, coal, metallurgy, petrochemicals, coalification, environmental protection, cement, papermaking, geological exploration, agriculture and animal husbandry, pharmaceutical research, and teaching.

Compliant with standards:

GB/T213-2008 "Method for determination of calorific value of coal"

GB/T384-1981 "Method for determination of calorific value of petroleum products"

JC/T1005-2006 "Method for determination of calorific value of cement black raw materials"

ASTM-D5865-2010 "Test Method for Total Calorific Value of Coal and Coking Coal"

GB/T30727-2014 "Method for determination of calorific value of solid biomass fuels"

The requirements of ISO 1928-2009 "Solid mineral fuels - Determination of total value and calculation of net calorific value using a bomb calorimeter".

Instrument features: 

Advanced electronic 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.

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

Fast testing speed, testing cycle ≤ 8min (rapid method) ≤ 15min (national standard GB/T213-2008).

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.

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.
