Product Description

General Introduction

Product use

Laboratory or industrial temperature shock test box with high quality for cheap price is suitable for electronic, auto parts, plastic, protection products safety performance test and product selection, testing of various materials of high, repeated low temperature resistance, test products for thermal expansion and contraction produced by chemical changes and physical damage.

Box Structure

Inside the box and the material of the stainless steel SUS304, external two-sided galvanized steel NC forming and surface coating protection.

Box test points for high temperature, low temperature, test area. The special heat insulation structure and hot and cold storage treatment. Test sample is completely still, application cooling air switching valve into high and low temperature, which were subjected to temperature shock.

Can independently set high temperature, the temperature and the temperature impact three different test functions, shock temperature can choose two or three boxes function, and have high, low temperature test. Air outlet and return tuyere wind gate switching mechanism of time for the completion of 10 seconds, temperature shock temperature recovery time to complete within 5 minutes.

system requirements

Using touch color liquid crystal display (LCD) interface, simple operation, can switch, English display operating system.

With RS-232 communication interface, can run the program and computer design, collect test data and records.

With full automatic and high precision system circuit, any operation complete control of processing by the P.L.C, a high precision temperature control, automatic control by P.I.D.

Abnormal conditions of operation, the screen immediately shows fault alarm, emergency stop test run.

system requirements

Circuit system load short-circuit protection; compressor overvoltage, overcurrent and low voltage protection; lack of power phase sequence protection; cooling system water protection; box District independent over temperature protection.
