Cheap Ebay Thermocouple


i brought this cheap thermocouple £17! but it was just a bit of wire (multimeter inc.) and whilst it has got a glass fiber sheath ther was a bit of shrink wrap round the buisness end!!(it can red to 1000C) so i bodged to gether this ceramic tube and drilled a hole through a soft face furnace brick. Thats 600c (1140f) which is more than enough for heat treating Aluminium, the qustion is now can i maintain the tempurature in the furnace +-10c?
