High Low Temperature Environmental Testing Chamber Humidity Lab
Test Machine HD-E702-800-4 Climatic Chamber.pdf Product Description: Environmental Test Chamber is a necessary test equipment in the fields of aviation,
automobiles, home appliances, scientific research, etc. It is used
to test and determine the parameters and performance of electrical,
electronic and other products and materials after high temperature,
low temperature, alternating humidity or constant temperature
environment changes . Product Features - Material quality of inner box is SUS304 # mirror-face stainless
steel imported, and outer box is steel plate and the paint. Box body is processed shape
using CNC machine tool, its shape is beautiful and fine.
- Heat preservation material used glass fiber cotton of
high-intensity PU foam and high density, which can avoid unnecessary energy loss.
- Large glass window design, viewing angle in all directions, hollow
electric plating film and anti-condensation design, built-in lights to
facilitate the test sample state of real-time observation in the course of testing.
- Large-size LCD display screen, simple operation, easy to edit
programs. PID with automatic calculation function, show failure message .
- An RS-232 communication interface, matching recorder, strong
expandability.
