DDSDevelopment history and product introduction of calorimeter

DDSIn terms of heat measurement, there are40Years of experience.

1972In the year,DDSProduced their * calorimeterAMPC(Automatic micro processing calorimeter).AMPCIt is a microprocessor controlled dual water isothermal instrument.

1980In the year,The revolutionary design of the tank is namedDRYTank orCP5(Technology), which means there is no need for a water jacket. Significant reduction in testing time and increase in instrument efficiency4Twice.

At this time, microprocessors appeared on the market, and we subsequently launchedCP500Type calorimeter. It provides a bright yellow hue, bringing vitality to the dull laboratory.CP500The type calorimeter is a fast, reliable, and highly accurate calorimeter for measuring calorific value. It was soon exported to the United States, Europe, and Scandinavia(peninsula)(Europe)Australia, the African continent, India and other countries and regions.CP500Type calorimeter is applied in many industrial fields, such as coal mines and food(Manufacturing and Research)Animal feed, cement production, brick and tile factories, waste, building materials, military weapons and explosives, fireworks and firecrackers, liquid fuels, etc;

In2002At the beginning of the year, we launchedCAL2KType calorimeter. It adopts dry technology and electronic technology.

In2004We launched it again this yearECOTheE2KWaiting for the model.ECOSuitable for processing samples with a daily volume of less than8One, andE2KType has high speed(6A sample/sky/can)Characteristics such as accuracy and moderate price.

In2007New Year'sE2KThe system has been upgraded again.

2015In the year,DDSlaunchCAL3K-APAutomatic high-speed oxygen bomb calorimeter.

CAL3K-APThe automatic high-speed oxygen bomb calorimeter uses isothermal adiabatic method-Still using the dry heat method, it uses an intelligent oxygen bomb tank that can achieve high repeatability and reproducibility. What is the fastest measurement speed3minReduced sample testing time.

The oxygen bomb tank is automatically filled with oxygen and monitored for pressure. Pressure can be changed (through program settings). The pressure of the tank is recorded during ignition and the pressure curve is monitored and analyzed.

In terms of air coolers: The new air cooler has replaced the traditional water cooler. It uses less energy to operate. The air cooler works better and has a faster cooling speed.

At room temperature, an air cooler may require6minYou can remove the tank from it14Cool to ℃4℃。

In terms of oxygen bomb tanks: The new oxygen bomb tank is a stainless steel tank body with a lightweight and compressed aluminum sleeve. This aluminum sleeve has the traditional functions of water and mixer.

The sensor is embedded in the side wall of the tank. The circuit is gathered at the bottom of the oxygen bomb tank and is vacuum sealed to prevent any liquid and dust from entering.
