In this test, cable samples are heated within a work tube at a programmed rate of rise; four samples can be processed simultaneously. A small flow of air is passed over the samples and then collected and analysed for acidity. Features:

Model | ADG 12/4 |
Max Temp (°C) | 1200 (°C) |
Furnace tubes (included) | Four IAP tubes 50 x 60 x 800mm, arranged 2 above 2 |
Inner tubes (optional) | Four clear fused silica (Si02) tubes 41 x 45 x 1000mm (note: silica tends to devitrify when used above 1000°C) |
Heated length | 550mm |
Heating rate | Less than 40 minutes to 800°C (better than 20°C/min to 1000°C) |
Temperature uniformity | The temperature at the centre of each of the four silica tubes will be within +-5°C of each other over a 300mm length, with no gas flow (BS 6425 requires +-17.5°C over 300mm with a small gas flow) |
Heating elements | Resistance wire spirals embedded in the inner surface of vacuum formed ceramic fibre cylinders |
Temperature sensor | Type R Pt/PT 13%Rh thermocouple |
Temperature Control | Carbolite 201 panel mounted digital PID controller giving pre-set control of the heating rate and maximum temperature |
Power control | Solid state relay incorporating zero voltage switching |
Power supply | 220/240V, 50/60Hz, single phase, 20 amps |
External Dimensions | 640mm (h) x 800mm (w) x 480mm (d) excluding tubes |
