225L 408L Temperature Humidity Testing Machine , High Temperature Low Humidity Chamber 150L
PT-2091 Constant Temperature & Humidity Testing Ma...
Application: Programmable constant temperature and humidity testing machine is applied to test the materials in heat-resistance, cold-resistance, dry-resistance, moisture-resistance.The language can choose either English or Chinese and with the touch-screen liquid crystal display screen, simple to operate and program easy to edit. It can show the system operating data, implementation and et-up process curve. A trouble occurs in operation, the screen automatically displays the trouble and provide method for trouble shooting.

Structure Features :
1. SUS304# stainless steel plate is adopted in the test case;There are test rails on both sides of the inner box;The insulation is made of at least 100mm rigid polyurethane foam.The front door of the inner box is connected with high-quality bakelite and fiberglass door frame as heat conduction partition, with excellent low temperature insulation performance;The airtight seal on the door is made of silica gel foam with a certain temperature resistance range.
2. Air supply circulation system: aluminum wind wheel with high and
low temperature resistance and multiple blades is adopted
uniformly. The upper louver is driven by the motor to supply air,
and the lower side returns air.
● insulation material: hard polyurethane foam + glass wool
● Camber door:
1. single door, left open, handle on the right
2. product observation window, three-layer vacuum layers
3. embedded non-reaction plane handle
4. door hinge: SUS# 304
5. light lamp in the test box, 11W
6. silica gel foam strips , 2 pieces
7. electric heating automatic mist removal device 1 set
8. touch frozen scald device, 1set
