Scope of application:

It is mainly suitable for measuring the calorific value of solid or liquid combustible substances such as coal, petroleum, chemical, food, wood, etc. in industries or departments such as electricity, coal, papermaking, petrochemicals, cement, agriculture and animal husbandry, medicine, scientific research, and teaching.

Performance characteristics:

The ZDHW-6A embedded fully automatic calorimeter adoptsscience and technologyThe industrial serial port display technology enables intuitive display of experiments and capacitive screen touch control equipment.

■ Unique ultra-high bit analog-to-digital conversion technology: This product uses a 24 bit analog-to-digital converter for higher accuracy and precision.

Adopting domestic technologynew typeThe "circulating water cooling technology" quickly returns the outer cylinder water temperature to near the starting value, reduces the cooling correction coefficient, and makes the measurement results more accurate.

Internal device: Imported mixing motors are used internally to drive sheet-like blades for constant temperature mixing, and submersible electric mixing is used for the mixing of the outer cylinder, making the mixing more uniform and convenient. The instrument adopts a fused cotton thread ignition method.

High degree of automation: By using a water quantification device and combining it with an automatic water circulation system, the water volume in the inner bucket can be accurately quantified without the need for manual weighing and adjusting of water temperature. This avoids errors caused by human factors during the operation process, reduces the labor intensity of operators, shortens testing time, and improves work efficiency.
