1. KOMEG Temperature Humidity Test Chamber Features:
Our housing are steel plate galvanized and zinc painted inside.
To keep its outstanding appearance in long term service, we apply the coating technology of automotive for the surface treatment:
Acid-cleaning, coslettise, drying, spraying, baking, then packing back.
This technology hardly causes coating damage. Long time no lose color.
It’s easy for cleaning and maintenance.
The refrigerating system is the core/heart part of the test chamber.
For enhance the whole refrigerating system performance, we use professional and advanced copper tube bending machine, this can decrease the welding points over 50%, and decrease right-angles of the tube, Also less welding points can reduce the resistance when the liquid flowing inside, to keep compressor working in higher efficiency, and better energy-saving.
2. High temperature limits of test chambers
There are many types of test chambers, but they all high and low temperature limits. Let's take a look at the typical high temperatures thresholds and why they exist.
Test chambers usually have wire heaters made of a material called Nichrome. By placing successive loops of heater wire, a greater amount of heat that is generated. The result looks a lot like the inside of a toaster. Fans circulate the air past the heaters, so the samples in the chamber are not exposed to radiant heat. It is very easy to add heaters and increase the speed and / or high limit of a chamber.
KOMEG chambers typically have a high temperature limits under 200°C. Here is a break-down of why a chamber's high temperature limit exists:

5. Technology Advantages: KOMEG provide you excellent test chambers
1. Trumphy processing machine and car coating technology let the tets chamber feel delicate touch and excellent user experience
2. Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design; built-in LED lights to facilitate the test sample state of real-time observation in the course of testing; double door design, the inner big glass door with hand-in holes for the convenient operating.
3. Material quality of inner box is SUS304 # mounted stainless steel imported, and outer box is steel plate and the paint process applies automobile coating technology. Box body is processed shape using Triumph processing machine, its shape is nice and neat.
4. 7 inch or 10 inch Full Color LCD touchscreen controller, simple operation, easy to edit programs. PID with automatic calculation function; self-diagnostic function, show failure message and failure shot solutions step by step.
5. An RS-232 and RS-485 communication interface, matching recorder, strong expandability. We also support remote control by PC via wifi or wire (recommended).
6. Packaging:
Programmable Climatic Test Chambers are covered with air bubble film before put them into the strong plywood case, which not only has good shock absorption, impact resistance, heat sealing and also has the advantages of nontoxic, odorless, moisture corrosion, crash-proof, etc.
