Constant Temperature Humidity test chamber

Product catalog summary

Standard Compliance
The temperature test chamber complies with several international and military standards, including IEC68-2-1, IEC68-2-2, IEC68-2-3, IEC68-2-30, IEC68-2-14, and MIL-STD-810D. These standards ensure the chamber's reliability and performance under various environmental conditions.

Performance Parameters
The test chambers are available in different models (BTH-80, BTH-150, BTH-225, BTH-408, BTH-800, BTH-1000) with varying test space dimensions. All models use air-cooling methods and have a temperature range from 0°C to -70°C up to 150°C, depending on the type. The humidity range is between 20%RH and 98%RH. Temperature fluctuation is ±0.5°C, and humidity fluctuation is ±2%RH. The chambers maintain temperature deviation within ≤ 2.0°C and humidity deviation within specified limits based on humidity levels.

Material and Construction
The internal material is 1.2mm thick SUS#304 stainless steel, resistant to high and low temperatures. The external material is flame-retardant high-strength PU polyurethane foam for insulation.

Control and Safety Features
The chambers are equipped with a touch screen programmable PLC with USB and RS485 interfaces for computer control and remote monitoring. Safety features include an explosion-proof pressure relief device, mobile phone alarm, smoke exhaust, and fire extinguishing devices.
