“TEMPO” make photostability chamber are made of double walled construction with backside as triple walled. The fluorescent light & UV light fitted on the top side of the chamber. Full view inner tough glass door & a front door with magnetic gasket & lock. The motorized blower is fitted on the backside for uniform temperature & humidity. The 3” thick PUF insulation to ensure stable temperature & humidity. The unit is provided with the adjustable stainless steel rod trays. The equipment is mounted on caster wheel for easy movement.

Technical Specification

Controlling System

Two separate imported microprocessors based autotune PID controller with CE mark & dual display of set value & process value for temperature & humidity with direct %RH.

Air Circulation

The motorized blower at the backside of the chamber develops a unique air ow system which ensures maximum uniform temperature and humidity condition inside the chamber.

Heating System

High quality U shape SS tubular heater is used for better heating.

Humidity System

Steam injection system (non-condensing type) and reservoir tank with water level arrangement with indicator.

Refrigeration System

CFC Free hermetically sealed Emerson Copeland make compressor for better cooling with R134 A (eco friendly) refrigerant with a time delay to safeguard compressor system.


50 mm validation porthole with silicon rubber seal to insert sensors for validation. Full view observation acrylic door with a gasket to observe the sample inside the chamber. Interior illumination for working area. Specially designed stainless steel rod trays ensure uniform temperature distribution.

Safety Features

Additional safety thermostat to cut of dry heater supply in case temperature of overshoot. Float switch to cut off the wet heater supply in case of low water level. Audio & visual alarm. Compressor ON delay timer (2 min.) to safeguard the compressor.  Inbuilt overload protector provided for a hermetically sealed compressor. After opening the door UV light is automatically switch off.
