Compound probe

Product Introduction

The KD-10 temperature measurement and sampling composite probe is used for temperature measurement and sample collection during steel and iron smelting in the metallurgy and machinery industry. It has a series of advantages such as simple structure, easy operation and high accuracy. The temperature measurement and sampling composite probe is composed of a sampler and a thermocouple, so that steel samples and temperature data can be obtained at the same time and at the same place. It can obtain more accurate important data during the steel smelting process.

Comparison of composite temperature measuring samplers vs. single samplers: In the metallurgical industry, temperature measurement and sampling are always carried out. For a single fast thermocouple and sampler, temperature measurement and sampling can only be performed separately, and the operating tools used (thermal measuring gun and sampling gun) must also be two. The composite temperature measurement sampler is combined into one. In addition to having good technical performance, it brings a lot of convenience to storage, transportation, etc.

The Compound Probe (also known as a Combined Probe) is an advanced, multi-function sensor designed for real-time analysis of multiple parameters in molten steel. Commonly used in secondary metallurgy, the compound probe integrates the measurement of temperature, oxygen activity, and metal sampling into a single immersion probe. This allows steelmakers to improve process control, reduce measurement time, and enhance steel quality.
