1 Typical performance specification for the system’s internal chamber. Insert is required for higher accuracy.
2 Specified low temp is 5°C, but typically temp is 15°C below ambient. For high accuracy, insulated door is recommended.
3 Adjustment of system using standard calibrated by 2-pressure readings
4 After chamber reaches and maintains temperature equilibrium.
5 Laboratory certificates of Thunder Scientific control probe calibration (Accredited NVLAP 200582-0) provided with system.
6 This accuracy stated represents a worst case scenario. Typically the accuracy is ±0.6% or better.
7 To achieve low RH values, dessicant must be 50% unused or better. To achieve high humidity values, system must be warmed up.
8 System software calculates dew point in real time to prevent condensation.
