Formaldehyde Climate Chamber

Product Details

Environmental Conditions

• Operating Temperature: Generally, the temperature should be between 15°C to 40°C, as required by climate chambers produced by Guangzhou Dejun Instruments.
• Operating Humidity: Typically, the environmental humidity should range from 5% to 90% RH.

Temperature Control

• Adjustable Range: Temperature is usually adjustable between 18°C to 30°C or 10°C to 40°C, with a deviation typically between ±1°C to ±0.5°C.
• Uniformity and Fluctuation: Temperature uniformity is generally around 1.0°C, and fluctuation is between ±0.3°C to ±0.5°C.

Humidity Control

• Adjustable Range: Relative humidity is typically adjustable between 40% to 60% or 30% to 80%, with a deviation between ±3% RH to ±5% RH.
• Fluctuation and Uniformity: Humidity fluctuation is generally between ±2% RH to ±3% RH, with uniformity around 3% RH.

Air Circulation

• Air Velocity: Typically ranges from 0.1m/s to 0.5m/s or 0.1m/s to 2m/s.
• Air Exchange Rate: Generally ranges from 0.2m³/h to 2.0m³/h or 0.2 times/hour to 3 times/hour, with a deviation of ±3% to ±5%.

Background Concentration and Gas Tightness

• Background Concentration: The formaldehyde concentration in the air of the chamber should not exceed 0.006mg/m³ when empty.
• Gas Tightness: Under a 1000Pa overpressure condition, the gas leakage rate should not exceed 0.005m³/min or 10⁻³×1m³/min.
