Temperature & Humidity Suitable for 25 °C& 60% RH, 40 °C & 75% RH, 30 °C & 65% RH
Specially designed chambers to carry out stability studies at low humidity conditions such as 25°C & 40% RH, 40°C & 25% RH NMT, 30°C & 35% RH

INTELLIGENT CONTROL SYSTEM
The controlling system having is PLC Base and PC communication on Ethernet and data acquisition system complying with 21 CFR Part 11

HUMIDITY SYSTEM
Humidity is by steam injection. Humidity system consist of boiler tank, which is fitted with two nos. of boiler heaters, one heater works as a stand by and automatic switch over to stand by heater if regular fails and give alarm.A water reservoir tank is connected to the boiler tank. DM water is preferred. A magnetic float switch provided for safety for boiler low level to cut off the its supply.

SENSOR
Temperature and Humidity transmitter 4-20mA used for measurement. Temperature in degree Celsius and Humidity in %RH with 0.1°C and 0.1%RH resolution.

COOLING SYSTEM :
CFC free, the cooling system consists of hermetically sealed compressor coupled with evaporation coil and condenser, safe guarded by time delay circuit. Refrigerant 134A.

ALARMS :
Audio and visual alarms are generated for temperature variation, utility failure.

SAFETY :
The unit is provided with safety devices for temperature over shoot in case of malfunction.

STANDBY SENSOR :
When controlling sensor fails it automaticallyswitch over to standby sensor.

The unit works on 230 Volts AC and 50Hz mains supply.
