Hot Spot Accessories

Customized For Hot Spot 110 Lab Furnace

Shelf System…

A shelf system essentially doubles the capacity of the lab furnace. Double the number of samples that can be fired in your Hot Spot while still protecting the floor insulation. It is constructed from our Buster M-35 insulation as the shelves, and dense alumina posts.

Calibration Rings…

A PTCR is a highly accurate ceramic temperature indicator which records the true heat treatment received by the fired product. They can be used as either a furnace calibration check or as a record of an individual firing. They are sold as a box of 15 with the lot specific temperature table.  Your Hot Spot comes preprogrammed, PTN2, to check calibration with a ring.

Datalogger…

The datalogger links the furnace to your computer, records the temperature history in real time and outputs the firing curve as an Excel file.  The Hot Spot temperature controller output, which varies as the process temperature changes, is supplied to a jack located at the rear of the furnace.  A six foot long cord that plugs into the jack is supplied to conduct this output.  The datalogger accepts 0-5V DC output +/- 0.1 accuracy, 0.001 resolution and 5 year battery life.

Setter Plates…

Zircar supplies setter plates made from our own alumina and zirconia fibrous insulation.  Both materials can withstand very high temperatures.  Our alumina setter is the same material that our Hot Spot 110 hot face insulation is made of.  It has excellent shock resistance and low thermal conductivity.  Our zirconia setter is rated for continuous use at 1800 oC.  Both products are available individually or as part of a setter package.  It is not recommended to place material directly on the furnace floor.  Setters protect the furnace insulation.

Setter Spatula…

A setter spatula is a safe way to load and unload items hot materials.  The setter spatula can be purchased separately, or part of a setter package which includes eight setter plates.
