Introduction
DTWL - 30G high precision thermostatic chamber ( - 30 65- 30 75 30 80 )is a specially designed constant temperature chamber with air as the heat transfer medium. It has the technical characteristics of high temperature control accuracy, good uniformity of temperature field and small fluctuation. There are many temperature measuring instruments that cannot contact the liquid constant temperature source, and are not suitable for calibration in a constant temperature bath. The emergence of a high - precision temperature box solves the calibration problem of such instruments and fills the gap of the constant temperature source and provides a complete solution.
Features
Using constant temperature liquid bath technology, the temperature field is more constant
Temperature control adopts liquid bath constant temperature and other plate heating technology. After the liquid medium is controlled to a constant temperature in the constant temperature bath, it is circulated to the outside of the working cavity. Through the heat radiation method, the temperature of the working cavity is constant and uniform. The cooling method has a qualitative leap in temperature indicators.
Intelligent
Integration of measurement technology and internet of things technology, wifi remote control, making measurement easier.
High - definition touch screen control, multi - touch, greatly improve the user experience.
