Overview

The temperature controlled aluminum furnace body is made of high-quality rolled aluminum ingots, with good thermal conductivity and uniform temperature between each furnace hole. The furnace hole depth reaches 65 millimeters, and the test tube has a large heating area, which heats up quickly and is conducive to the rapid digestion of samples. Applicable to departments such as agriculture, forestry, environmental protection, geology, petroleum, chemical engineering, food, as well as higher education institutions and research departments, for pre digestion treatment of samples such as plants, seeds, feed, food, soil, and ores before chemical analysis; Used in conjunction with a nitrogen analyzer.

Product Details

The LWY84B far-infrared temperature controlled digestion furnace can be used in agriculture, forestry, environmental protection, geology, petroleum, chemical industry, food and other departments, as well as higher education institutions and scientific research departments for digestion treatment of plant, seed, feed, food, soil, ore and other samples before chemical analysis. It can be used in conjunction with an ammonia analyzer.

This device needs to adopt an integrated structure of controller and furnace body, fully considering the actual usage information of users in product design. All use light rail technology key switches and adopt some anti acid city god membrane straight plate technology. This design will not affect your normal use even if the user accidentally splashes acid onto the noodles during use. At the same time, the high brightness digital display allows you to clearly observe the temperature of the furnace body even in a bright environment. In the system control part, new single-chip microcomputer technology is used, and intelligent PID is adopted By adjusting the algorithm, precise temperature control of the furnace body can be achieved, which is more energy-efficient than traditional switch mode control methods and greatly improves control accuracy. At the same time, the power driving devices used in conjunction with it greatly reduce the failure rate compared to traditional thyristor methods, making it more reliable, stable, and less likely to interfere with the mains power supply.

2、 Working principle of far-infrared temperature control and digestion furnace

The LWY848 far-infrared digestion furnace adopts a new type of far-infrared element as the heating element. After the element is heated according to the elemental infrared timing, it mainly emits far-infrared rays of 1.5 to 2.5 meters, which are easily absorbed by the heating element and excite resonance, causing the temperature of the heating element to rise and accelerating the digestion of the sample. The temperature sensing element thermocouple measures the temperature of the protective body and transmits it to the bridge circuit in the form of electric music. The bridge circuit compensates for the cold end of the thermocouple, and then sends the signal to a single-chip microcomputer. The computer completes A/D conversion, converts the analog signal into a digital signal, and performs linear compensation. The digital display part displays it clearly and intuitively. The temperature value to be controlled is set by the setting part. And the measured temperature is compared with the set value by a microcomputer using PID Adjustment method: The heating power of the furnace can be adjusted with time and changes in conditions, and the furnace temperature can be kept constant at the set temperature.
