Constant temperature and humidity testing machine

Constant temperature and humidity testing machineBy simulating various climate environment temperature and humidity combinations, detect whether the adaptability and characteristics of the product itself have changed. Widely used in electronics, electrical appliances, metals, rubber, plastics, chemistry, building materials, and food Waiting for product testing.

Constant temperature and humidity testing machineThe touch screen display function adopts a high-sensitivity touch screen method, with direct touch options, which is convenient, intuitive and easy to operate. Real time automatic storage and representation of temperature and humidity PV/SP values, stored curves, group curves, and progress status in curve form. It can display the current program number, segment number, remaining time, and number of cycles, as well as the cumulative running time function. The temperature and humidity program settings are displayed as curves, with real-time display of program curve execution function. With a separate program editing page, each page can input up to 4 sets of segments, temperature and humidity, and time. It has the function of displaying program action status. The screen can be adjusted for 16 segments of backlight. The screen display protection function can be set to be timed, TIMER, or manually turned off. It has a power-saving standby function. It has separate functions for display and control, such as a vivid photo like daytime display, digital recording function, and provides an SD memory card.

Adopting an upward heat dissipation method to save space occupied by the machine and achieve optimal heat dissipation effect The door gap design using P.P non-metallic thermal insulation material can reduce energy waste by more than a quarter and control the effect. Lightweight and convenient front water replenishment method, with automatic water recovery and purification filtration device. The simple and innovative door handle design makes it easy to open and does not produce vibration when the box door is opened.
