80L Desktop Type Easy mobility High Low Temperature Environmental Chamber

Introduction:

This machine is used to simulate the rapid change of environment temperature, the ability to adapt to the environment.
Temperature and humidity testing machine can be divided into the program and the single sections of two kinds, single sections of test case set is simple, general directly controlled by the button; Programmable test chamber can be divided into many control, because the program is relatively complex and multiplicity, such as control with buttons, function key complex and difficult to remember that direct LCD touch-screen control, only need to set up the experimental program, complete the test without staff left-behind care, designed specifically for the busy laboratory staff.
