Fully Automatic Calorimeter HM-LR3

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: 

This machine is designed and manufactured according to GB/T384 and GB/T213 standards, and is suitable for determining the calorific value of petroleum products (gasoline, jet fuel, diesel, fuel oil, etc.) that do not contain water, as well as combustible substances such as coal, coke, and paraffin.

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. Adopting advanced technology from the United States, a 7.5-inch touchscreen LCD screen is used

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

Fast testing speed, testing cycle ≤ 8min (rapid method) ≤ 15min.

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 better than the requirements of the national standard.

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.
