Low temperature constant temperature and humidity testing machine refers to the relatively dense distribution of temperature and humidity, such as . B. Ordinary constant temperature and humidity chamber There is an error of 5 to 10 degrees, while the error distribution of the constant temperature and humidity laboratory assembled by QINSUN technology is within plus or minus 2 degrees, the fluctuation within plus or minus 0.5 degrees, the temperature analysis accuracy: 0.01℃, humidity analysis accuracy: 0.1%R.H., temperature control accuracy: ±0.2°C, humidity control accuracy: ±2%R.H.
They are suitable for aerospace products, electronic instrumentation, electricians, electronic products, materials, various industrial products or electronical Vitality The components are tested on their various performance indicators under high and low temperature, constant temperature or humid heat and constant humidity. The control part is located on the right side of the machine, and there are temperature controllers, control switches, etc., easy to operate, simple and easy to maintain. The laboratory selects high-quality materials and uses domestic advanced processing equipment for processing and shaping.
1. All equipment overheating;
2. Fan overheat protection;
3. The overall system is out of phase/out of phase;
4. Cooling system overload;
5. Cooling unit overpressure;
6. Protection against water shortage of humidification system;
7. Timing of all equipment;
8. There are other protection features such as leakage, operation instructions, and automatic shutdown after error alarm.
The ground is level and well ventilated
There is no strong vibration around the device
There is no strong electromagnetic field around the equipment
No flammable, explosive, corrosive substances and dust around the equipment
Adequate space is left around the device for proper use and maintenance,
2. Power Supply Conditions
Power requirement: AC380V±10% 50±0.5Hz three-phase five-wire system
Pre-installed power: Total power +2.0KW
The user must configure the appropriate capacity air or power switch, and this switch must be used independently for this device (recommended power switch capacity: 32A)
3 , Environmental Conditions
4. Water supply conditions (only required for damp heat type and water equipment)
Use pure water, distilled water, deionized water. Resistance ≥ 500Ω.m
5. Other Precautions
Low temperature constant temperature and humidity testing machine Opening the test box door during the Testing leads to temperature and humidity fluctuations in the box; if the door is opened many times during the test or leave the door open for a long time or the testmuster emits moisture, which may cause the cooling system heat exchanger to freeze and not function normally.
