Product Description
High and Low Temperature Humidity Test Chamber Temperature Introduction
According to the different needs of customers, Qinzhuo Environmental Testing Technology develops and produces high and low temperature test chambers for different temperature ranges.
The high temperature can reach up to 150 (if higher temperature is required, non-standard customization is required)
The low temperature range is divided into: 0 - 20 - 40 - 60 - 70
Among them, domestic testing mainly uses 0 , -20 , and -40 , while for foreign testing requirements, -60 and -70 are mostly used.
2 Introduction to Size and Dimensions:
In practice, the size of the small high and low temperature test box is 80L, with a width and height of (40 * 50 * 40CM)
Qinzhuo Environmental Testing Technology also offers several different standard sizes such as 150L, 225L, 408L, 800L, and 1000L.
In the actual business process, Qinzhuo Environmental Testing Technology can quickly customize non-standard products according to customers' requirements for a volume of over 1000L.
High and Low Temperature Humidity Test Chamber Main features:
Can achieve higher performance
Compared with ordinary temperature and humidity chambers, it has a faster temperature rise and fall rate: heating rate: 7 /min, cooling rate: 3-5 /min. Humidity range: 10% to 98RH.
Corresponding to high heating and high load test
The maximum allowable heating load is up to 4500W, suitable for high load heating reliability testing of electronic components related to semiconductors and automotive parts.
Convenient for renovation, with strong expandability in functionality
Structurally, it is easier to carry out modifications, such as stacking up and down modifications on top; The left and right sides can be combined for cabinet renovation.
It is easier to carry out related modifications to improve performance.
Energy saving cold output temperature and humidity control system, dual PID and water vapor partial pressure control, mature technology and extremely high accuracy.
The product is green, environmentally friendly, and energy-efficient.
Network control and data collection can be performed through interfaces (RS-485/GPIB/Web Lan/RS-232C).
Standard left and right cable holes (50mm) are provided for easy connection of samples and multiple measurements.
The controller adopts a color LCD touch screen, which is easy and convenient to operate
The controller allows for the selection of both fixed value and programmed control to adapt to different applications.
Program control can set 40 modes, with 99 steps set for each mode. Repeat the cycle up to 999 times.
Easily switch between multiple languages (Simplified Chinese, English) and store experimental data on a USB drive.
Multiple optional items can be added to meet the diverse needs of customers.
Additional safety options such as pressure relief valves, smoke sensors, emergency stop switches, alarm output terminals, and three color lights can be added.
Standard air-cooled specifications for easy product movement and installation.
Performance parameters:
1. Test environmental conditions: The ambient temperature is+5~+28 , the relative humidity is 85%, and there is no sample in the test chamber
2. Testing methods: GB/T 5170.2-2008 Temperature Test Equipment, GB/T 5170.5-2008 Damp Heat Test Equipment
3. Temperature range: 0 /-20 /-40 /-70 ~+150
4. Control accuracy:
a. Temperature: 0.2 (difference between controller set value and controller measured value)
b. Humidity: 2.5% (difference between controller set value and controller measured value)
5. Temperature fluctuation: 0.5 (temperature fluctuation is half of the difference between the highest and lowest temperatures measured at the center point)
6. Temperature error: 1 (the average temperature displayed by the studio temperature controller minus the average temperature measured at the center point)
7. Temperature uniformity: 2.0 (temperature uniformity is the arithmetic mean of the difference between the highest and lowest temperatures measured in each test)
8. Heating rate: adjustable at 3 /min (non-linear no-load)
9. Cooling rate: 1 /min adjustable (non-linear no-load)
10. Humidity range (only for humid heat type): (20-98)% RH (refer to the temperature and humidity controllable range diagram, no active humidity or thermal load) Programmable constant temperature and humidity test chamber temperature and humidity controllable range diagram
11. Relative humidity error (wet heat type only): 2.0% RH
12. Work noise: A-level 65dB (A) (measured in a soundproof room with low echo and ambient temperature of 25 ); Using A-weighting, test the average of 8 points; Each testing point is 1 meter horizontally away from the noise source and 1 meter above the ground in height
