80L Constant Temperature and Humidity Test Chamber
PRODUCT DETAILS
Product Details
Temperature and Humidity Range
-
Temperature Range: Typically between -70°C to 150°C. Common options include RT + 10°C to 100°C, -20°C to 150°C, -40°C to 150°C, -60°C to 150°C, and -70°C to 150°C.
-
Humidity Range: Generally between 20% to 98% RH. Some equipment with added dehumidification devices can achieve humidity as low as 5% RH.
Temperature and Humidity Control Accuracy
-
Temperature Fluctuation: Typically required to be ≤ ±0.5°C.
-
Temperature Deviation: Generally ≤ ±2°C.
-
Humidity Fluctuation: Typically ≤ ±3% RH.
-
Humidity Deviation: Generally ≤ ±2.5% RH.
Heating and Cooling Rate
-
Heating Rate: For example, from room temperature to 150°C, the heating rate is usually around 20 to 30 minutes. Some equipment may have a heating rate of ≥ 2-3°C/min.
-
Cooling Rate: For example, from room temperature to -20°C, it typically takes about 40 minutes; from room temperature to -40°C, it usually takes about 60 minutes; and from room temperature to -70°C, it typically takes about 100 minutes.

Control System
-
Controller: Often equipped with imported microcomputer-based temperature and humidity integrated controllers, supporting multiple PID control functions.
-
Sensors: Temperature sensors are typically platinum resistance PT100Ω, while humidity measurements are usually taken with solid-state electronic sensors.
Safety Protection and Other Features
-
Safety Protections: Includes over-temperature protection, power failure protection, fuse-less switches, compressor overload protection, high refrigerant protection, temperature limit protection, and fault alarm systems.
-
Power Supply: Typically AC220V/380V ±10%, 50/60Hz.
-
Power Consumption: The power consumption varies depending on the model and specifications, typically ranging from 2.8KW to 4.5KW.
