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. One - key start, full automatic control, shorten the training period of measurement personnel. Timing switch machine, remote switch machine, save time and improve verification efficiency. Wide temperature range High - precision temperature box series products can provide constant temperature environment within the range of - 40 100 Meet JJF1407 - 2013 WBGT Index Meter Thermometer Calibration Regulations Meet JJF1366 - 2012 Temperature Data Acquisition Instrument Calibration Specification High precision air bath constant temperature source Using high - precision temperature control sensor, with imported temperature control table did not achieve high - precision temperature control, low indication deviation Excellent quality The shell adopts thick plate phosphating, passivation, spraying, anti - corrosion, anti - rust, salt spray resistance; Liner adopts SUS304 High - precision sensor, using imported high - precision platinum resistance sensor Function HD touch Using high - resolution capacitive screen, the display is clearer, multi - touch support, in line with customer mobile phone touch operation habits.

Silvered mirror is manufactured by plating silver and copper layers on the surface of quality float glass through chemical deposition and replacement method and showering primer on the surface of the silver and copper layers as the protection of the silver layer. Being made through chemical reaction, chemical reaction between the glass and the air or moisture or other substances in the environment may occur, giving rise to the peeling or flaking of the lacquer or silver layer, so it generally requires critical production and processing technology, environment, temperature and quality.
