Product Description

General Introduction

Product use

Laboratory or industrial constant temperature and humidity test box with high quality for cheap price is used to test and determine the electrical, electronics and other products and materials for high / low temperature or constant humidity of ambient temperature changes after the parameters and performance, aviation, automobiles, household appliances, research and other areas of the necessary test equipment.

Box Structure

Adopting the NC machine tool processing molding, beautiful appearance, novel and handle with no reaction, simple operation.

The bladder imported advanced stainless steel (SUS304) mirror panel or 304B argon arc welding is made by the bravery of A3 steel spray.

controller

Using microcomputer temperature and humidity controller, temperature and humidity control is accurate and reliable.

Large observation window attached to the lights keep in bright and double glass, clear observation box at any time.

The establishment of an independent limit temperature alarm system, exceed the limit temperature automatically stop, ensure the safe operation of the experiment is not an accident.

Optional recorder, printer can print record set parameters and scanning the changes of temperature and humidity curve, 4 ~ 20mA standard signal.

The box on the left side of the test with a diameter of 50mm hole.
