[QUOTE="user name, post: 315701, member: 1719"] This is the response from Orton: The TempTAB product is better for several reasons. [LIST=1] [*]The heating rate used to establish the temperature data is 5°C/hr for TempTAB, where the PTCR rate is 2°C/hr. Dental ovens fire between 5-10°C/hr on heating. The TempTAB match that rate better. [*]TempTAB has several data columns for whatever hold time you use from 10 minutes up to 4 hours. The PTCR charts are only good for a 1 hour hold. We typically see Zirconia held for 2 hours. [*]The TempTAB are made from high purity Alumina Oxide, 99.8% Al2O3. The Alumina used in PTCR contain some silica which can vaporize and deposit on the Molybdenum Disilicide Heating elements. [*]The TempTAB 700 work best for 1550°C. The maximum temperature for the TempTAB 650 is 1520°C. [/LIST] Ill continue to study. First is to try a new batch of Tabs. [/QUOTE]
