Box structure:

The inner liner of the box is made of imported stainless steel (sus304) plate or 304b argon arc welding, which has good corrosion resistance.

The outer shell of the box is made of A3 steel plate sprayed with plastic.

There is a large observation window with lighting to keep the box bright, and double-layer glass is used to clearly observe the situation inside the box at any time.

A test hole with a diameter of 50mm is provided on the left side of the box.

Internally equipped with 2 stainless steel grille shelves and platinum temperature and humidity sensors.

Equipped with pressure relief and explosion-proof windows.

control system

Adopting a touch screen system and equipped with a programmable microcomputer temperature and humidity controller, it has a large screen color image and can display temperature and humidity curves in real time. 24 bit high precision, can display two decimal places, can save data for 3 months, and provides USB communication interface to backup historical data. It can also record error history. Built in automatic tuning function.

Main configurations:

Electrical system: including nickel chromium alloy electric heater, drawer water tank water supply device, forced circulation ventilation, high-efficiency refrigeration machine and energy regulation, etc. High quality products are selected for AC contactors, temperature signal solid-state modules, thermal overload relays, etc.

Refrigeration system: air-cooled, using two fully enclosed stacked refrigeration compressors, equipped with oil separators, drying filters, pressure controllers, condensate water collection trays, and using special sound-absorbing sponges for sound absorption.

Other accessories: equipped with one digital temperature and humidity meter; Configure 2 sets of shelves, 1 cable hole, 1 plug hole cover, and 1 outlet pipe. The main components are all imported from overseas with original packaging.

Device dimensions:

Internal cavity volume: 150L

Inner box size: 500600500mm

Outer box size: 75015501050mm

Protective measures:

It has multiple protection functions such as leakage/surge prevention protection, temperature/humidity sensor open circuit or short circuit protection, three-layer over temperature protection, compressor protection, fault abnormal protection, dynamic high and low temperature protection, etc., to ensure the safe and reliable operation of the equipment.

Environmental requirements for use:

Allowable working environment: 0-35 ℃, performance guarantee environment: 5-25 ℃.

Require the installation ground to be level.

The distance around the test chamber is 600mm, and the distance between adjacent walls or objects is 300mm.

To ensure the stable functioning and performance of the test chamber, a location with a perennial temperature of 15-35 ℃ and a relative humidity greater than 85% should be selected. The environmental temperature of the installation site should avoid sudden changes.

It should be installed in a place without direct sunlight and good ventilation, away from combustibles, explosives, and high-temperature heat sources, with less dust, and as close as possible to the power supply.

High and low temperature environment test chamberAccurate temperature control, stable operation, easy operation, can provide reliable environmental simulation conditions for product quality testing and research and development. In addition, there may be certain differences in the specific products of different manufacturers. It is recommended to consult Guanghaotan manufacturer in detail before purchasing to obtain more accurate product information and technical support
