1. Performance 

Programmable Temperature Humidity Chamber LCD Display P.I.D control can simulate both temperature and humidity. Controlled humidity from 10% RH to 95% RH can be maintained within the dry-bulb temperature range of +10°C to +85°C, limited by a 6°C dew point. For lower dew point conditions (low RH or relative humidity at low dry-bulb temperatures), you will need dry air purge or GN2 (gaseous nitrogen) purge. See the humidity range chart on the specification page of each temperature-humidity chamber for humidity range limits.
