-40°C to 85°C (±2°C) for RT/UNC -- user-defined

Dwell Time at Extremes: ≥15 minutes – user-defined

Number of Cycles: 100 pass/fail, 500 for information for CO；500 pass/fail, 1000 for information for RT/UNC

Cyclic Moisture Resistance Test

Temperature Profile: Refer to below profile -- user-defined

Relative Humidity: 85-95% at 75°C; uncontrolled at 25°C & -40°C

Dwell Time at Extremes: 3 to 16 Hours – user-defined

Number of Cycles: 5 complete cycles (each complete cycle has 5 sub-cycles)

Features

We can use the laser source, optical power meter, thermostat box, and optical switches, through the control software, achieve automatic temperature control, automatic switching test. In the field of production and manufacturing testing, the module + platform testing solution has great advantages in instrument expansion, data/report autosave, programmability and so on.
