Alert Unexpected Interruption of Electrical Power or Unauthorized Change.4 digit Password lock.

Air Circulation : [Laminar type]

The chamber is provided with best air circulation to give better temperature uniformity this is achieved by using one set of motor & blower in baffle wall Compartment to push treated air in w orking chamber. This system gives better than 1 deg c. temp. uniformity in working chamber. Uniform forced air circulate across the shelf via air diffusers on the top wall. Uniform horizontal or vertical airflow shall be provided for maintaining uniform temperature and RH in the room. System for adjustable forced air exchange shall be provided with up to 20 air exchanges per hour of fresh air to the room or its equivalent and an option to shut it down when not required. No direct radiation on the specimen

Temperature Fluctuation : + 0.2°C, Temp. Uniformity : + 2 °C
Humidity Range : 10% to 95% RH, Resolution : 0.1% Accuracy : + 2%R.H, Uniformity : ~+ 5%

Xenon Short Arc Lamp :

150 / 300 / 500W Max current 25 amp, Voltage 20V max, Ozen free and about 1000 hours life time in the centre of the chamber for light illumination in solar wavelength.

Heating / Humidification & Dehumidification :

Imported Encolite heaters up to 3 K.W. Air Heaters are provided for heating above ambient temperatures. Humidity is controlled by steam injection method. The boiler tank is used for steam generation, Electro-magnetic switch is used for sensing the Water Level. Thus eliminating the humidity interruption. De-humidification coils are installed below the cooling coils for lower humidity.
