Digital Programmable Environment Chamber for Temperature and Humidity

Product Description

Product Introduction:     

This series of products of constant temperature and humidity testing machine is mainly used to simulate the harsh high temperature, low temperature or damp heat environment that may be encountered in the transportation, storage and use of electronic instruments, new materials, electricians, vehicles, metals, electronic products, aerospace materials, etc.; or in the environment of high temperature, low temperature and alternating humidity and heat, inspect the high temperature, cold resistance, damp heat resistance of materials, accessories or instruments and equipment, and the reduction of the damage life that may be caused.

Product features:

(1) Box structure:

Inner box material: SUS304# stainless steel plate is used, which has the advantages of acid resistance, corrosion resistance and easy cleaning.

Outer box material: cold-rolled steel plate baking paint treatment.

Door handle: non-reaction, explosion-proof door handle, easy to operate, safe and reliable.

Thermal insulation system: ultra-fine glass fiber is used to fill the insulation area, and the connecting parts of the inner and outer boxes are made of non-metallic high and low temperature resistant materials to effectively reduce temperature conduction; The door seal is made of refined silicone rubber, so that there is no aging and hardening under high and low temperature conditions, and the sealing is more reliable; The humidification method is isolated humidification.

Moving and positioning device: The bottom of the machine is equipped with high-quality fixed PU movable wheels, which can easily move the machine to the designated position and fix the casters.

Sample holder: SUS304# stainless steel punching and bending into a mesh, easy to use, adjustable spacing between material racks, two pieces of standard configuration, uniform distribution of samples according to the load of 25kg.

Test hole: open a test hole of Φ50mm, and attach the corresponding thermal insulation accessories and special sealing soft plugs

Observation window: Double-layer vacuum strengthened glass, and the inner glued sheet conductive film is heated and defrosted to clearly observe the test process.
