The DTA uses a dynamic measuring principle. This instrument will measure endothermal and exothermal heat flow between the sample and reference (enthalpy).
In general these heat flows are characteristic of chemical or physical changes of the sample. The test sample and an inert reference material are heated simultaneously in the same atmosphere.
Both the sample and reference material temperatures are measured with thermocouples.
Then these 2 thermocouple output voltages are subtracted from one another. There suit is a low voltage signal which is proportional to the endothermal and exothermal reaction.
Endothermic sample reactions absorb heat and exhibit a lower sample temperature when compared to the reference material.
Exothermic reactions produce heat and exhibit a higher sample temperature when compared to the reference material.
Options include operations in vacuum and inert atmospheres -

One dual scale machine is now available for car-rying out impact tests according to A.S.T.M. test method C 368, the lower scale for bone china domestic tableware, and the heavier for carrying out tests on more robust ware (e.g hotelware).
The impact tests are carried out on either glazed or unglazed samples at the centre of both flatware and hollow ware, at the rim of hollow ware, and edge chipping tests at the rim of flatware.
The tests at the centre of the of the specimen are carried out to determine: (a) the magnitude of a blow that will be required to produce and initial fracture and (b) the amount of energy necessary to produce complete failure. -

Read MoreQuick ViewMulti Chamber (Variable Gradient) Kilns – TG.3 / TG.6 XL / TG.9 Mk.III
The new range of individual chamber temperature gradient kilns, The TG.3, TG.6 XL and the TG.9 Mk.III (pictured below) are unique in design as they offer the user the ability to set the top temperature to be achieved in each chamber. Hence the user is no longer constrained to a fixed gradient, as was the case with the traditional gradient kilns. Each chamber has its own thermocouple and electrical contactor that is linked back to the TC.S2 / TC.M2 microprocessor controller. This allows the user to program the firing cycle for one of the chambers (this will be the hottest chamber). The temperatures in the remaining chambers will then be set as differences in tem-perature.
The TC.S2 / TC.M2 controller will allow up to able to store 99 programs with up to 99 segments per programme, and can simultaneously display the temperatures in three adjacent chambers.
