Heating Instruments

High Temperature Furnace

High Temperature Furnace is one the most popular products from APS Instruments. Extremely light on weight and this makes it a product very unique in comparison to other High Temperature Furnace that you will find in the market. Controls maximum temperature up to 1200°C grooved to refectory type and has a working temperature up to 1150°C. To take control of the heat, this furnace has a slimmer state and we call it as energy regulator. The outer body is made out of thick mild steel with duly painted surface. This apparatus is complete with pyrometer.

There are also some significant features which are fitted with this apparatus such as thermo couple, two neon lights with wire and plug supply. It works on 220/230 Volts AC, (with Silicone Fiber insulation). By adding some extra cost you can have a digital temperature controller cum indicator which is completely based on P.I.D.

Vacuum Oven

Apart from that we are supplying our vacuum oven in India, catering to a variety of customers ranging from Defense Installations, Research Laboratories, Educational Institutes and various R& D laboratories of leading national and multinational companies.

There are many salient features which also being included and this includes, high tech vacuum oven double walled, precise vacuum control; 28” (70.2 cm) Hg displayed on analog gauge, highly energy sufficient, inside chamber made of thick stainless steel SS-304, long life, low maintenance and calibrated with protocol documentation.

Our vacuum ovens are double walled convection heated units. Outer body of our vacuum oven are constructed out of thick PCRC sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated.. The inner chamber is made of heavy gauge stainless steel sheet of SS-304 grade.

The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency in our vacuum ovens. The unit is mounted on a sturdy steel frame and provided with castor wheels (Large Sized Models Only) for easy movement inside the laboratory. The unit is provided with one stainless steel shelves.

Our unit has three sided heating systems and this comprise of air heaters made of Kanthal A-1 wires of suitable wattage. The temperature is evenly disturbed throughout the chamber through efficient motor fans ensuring very good temperature sensitivity. Temperature range of our standard laboratory oven models are 5° c above ambient temperature to 150° c.

However we have the capacity to modify the same to suit the individual specialized requirements of our customers. Temperature inside our hot air ovens are controlled with a sensitivity of + 1° c or better. Front panel of our units comprises of on/off switches heating and mains indicator lamps, temperature controllers/Thermostat.
