MAKE: CITY INSTRUMENTS 

(An ISO, CE, NSIC, MSME, GEM, Trade Mark, IEC Certified Company)Maximum temperature: up to 1200˚C

Working Temp. Range: up to 1100ºC.

Temp. Accuracy: ± 1ºC.

Light weight with ceramic Fibre wool insulation (instead of Brick insulation). The outer casing is made of double walled thick P.C.R.C. sheet, finished with attractive powder coating.

Elements are made of KANTHAL “A-1” wire in coil form placed in the ribs of the tiles to have a free radiating heating. Backed by Zirconia cerewool insulation, which avoids loss of energy, this arrangement also assures the most uniform distribution of heat.

The weight & size of furnace is of one quarter and 30% respectively as compare to Bricks Furnace. A viewing cap is also provided on the door.

Temperature of the furnace is controlled by microprocessor based Programmable controller (1x14 segment, dwell, hold, ramp, timer all with Also provide calibration report of controller by NRL lab if requirement by costumer, with soft touch keypad and dual display of process & set temperature. The overshoot & undershoot of temp. Variation is drastically reduced compared to normal ON / OFF type-controlled furnace.

K type Sensor

To work on 415 Volts A. C. Three Phase Supply,

25 to 30 Ampere each Phase Approx., 12 to 15 kilo watt load Approx.
