1. The double-layer stainless steel spring is extensible and more stable: It is applicable to containers of diverse capacities and can be equipped with multiple reagent bottles, catering to different experimental demands.
2. Upgraded 304 stainless steel with superior anti-rust property: The water tank, cover, and support are all fabricated from 304 stainless steel.
3. Dual digital display configuration: Intuitively and clearly presenting temperature, rotational speed, and time.
4. PT100 sensor: The PT100 temperature sensor enables more precise temperature control.
5. Silicone drain pipe: Unscrewing it enables drainage simply and conveniently, without the need for movement.

Working Environment Conditions:
Water Bath Oscillator
1. Temperature: The temperature is controlled within the range of 5°C to 100°C.
2. Placement Environment: It should be placed on a level workbench, avoiding direct sunlight, and there should be adequate space around it for heat dissipation and operation.
3. Water Quality: Distilled or deionized water should be utilized in the water bath tank to prevent scale formation and corrosion.
Air Bath Oscillator
1. Temperature: The temperature is controlled within 5°C to 50°C.
2. Placement Environment: It should be placed on a flat and stable countertop, avoiding direct sunlight and strong electromagnetic interference.
3. Ventilation: Excellent ventilation conditions are necessary to ensure the equipment's heat dissipation and the accuracy of temperature control.

Precautions:
Water Bath Oscillator
1. Water Level Inspection: Before usage, it is necessary to inspect whether the water level in the water bath tank is appropriate, ensuring that the water level is higher than the heating tubes to avoid dry burning and damage to the equipment.
2. Water Quality Maintenance: Regularly replace the water in the water bath tank to prevent the accumulation of scale, which might affect the heating effect and the equipment's service life.
3. Sample Placement: Samples should be placed on a dedicated sample rack, avoiding direct contact with the wall of the water bath tank to avoid influencing temperature uniformity.
4. Temperature Control: When setting the temperature, it should be precisely set in accordance with the experimental requirements to avoid temperatures that are too high or too low, which could impact the samples.
5. Cleaning and Maintenance: Promptly clean up any debris and residues in the water bath tank after usage and regularly clean and disinfect the equipment.
6. Safety Precautions: Wear protective gloves during operation to avoid scalding from hot water. After usage, disconnect the power supply to ensure safety.

Air Bath Oscillator
1. Temperature Calibration: Regularly inspect the accuracy of the temperature sensor to ensure the temperature is controlled within the preset range.
2. Sample Fixation: Samples should be firmly placed on the sample rack to prevent shaking or dropping during oscillation.
3. Ventilation Requirements: Ensure there is sufficient space around the equipment to guarantee good ventilation and prevent overheating due to poor heat dissipation.
4. Cleaning and Maintenance: Regularly clean the dust and debris inside the equipment to maintain its cleanliness and good operational status.
5. Power Check: Before usage, inspect whether the power cord and socket are normal to avoid equipment damage due to power issues.
6. Safe Operation: During the equipment's operation, avoid opening the door to prevent influencing temperature uniformity and experimental results. After usage, disconnect the power supply and clean the interior of the equipment.
