PYROMETRIC RINGS AND CONES
BULLERS RINGS
Bullers firing trial rings are the best way of measuring temperature/time in all ceramic firing methods. No clay body support is required and a single ring is suitable for carrying out several different temperature measurements. Furthermore, it is not necessary to remove the firing material in order to position them. Temperature control is therefore made much easier. They make measurements and not estimates. Given their ease of use, they are also perfect for controlling multi-layer passage kilns and single-layer roller kilns.
10 °C graduated tables, minimum gauge reading approx. 2 °C. The Bullers firing trial rings are packed in cardboard boxes containing adout 100 pcs.
Series 89 for temperatures ranging from 750 to 1000°C

Series 75 for temperatures ranging from 960 to 1320°C
Series 73 for temperatures ranging from 1280 to 1440°C
Special gauge for the above.
Complete with conversion table and carrying case.

PTCR RINGS and BPCD DISCS
PTCR pyrometric rings and PBCD discs, have more or less the same characteristics and applications as Bullers rings. They are smaller and are measured with a digital 1/1000 micrometer.
