Tinytag data loggers monitor heat curing cycles during the production of custom made ocular prostheses
Tinytag Ultra 2 thermocouple data loggers are used to record temperature data during the heat curing of medical grade acrylic at Manchester Royal Eye Hospital .
NHS ocularists working in the Department of Ocular Prosthetics at Manchester Royal Eye Hospital are responsible for fabricating and fitting custom ocular prostheses , cosmetic shells and facial prostheses . Part of the fabrication process is the heat curing cycle , in which the medical grade acrylic which the prosthetic eyes are made out of is exposed to high temperatures so that it hardens and is suitable for wear .
The ocularists use Tinytag Ultra 2 thermocouple data loggers to monitor temperatures during the heat curing cycle to ascertain that the acrylic has been cured at the optimum temperature ( a temperature range of 200 C to 130 0 C for the correct amount of time ).
To monitor the heat curing cycle , the data logger ’ s thermocouple probe measures the temperature within the
heat curing tank , while the data logger itself remains outside the tank recording the readings taken by the probe . The data from each cycle is downloaded , viewed and analysed using Tinytag Explorer software . If the temperatures are found to have fallen outside the desired parameters , indicating that the acrylic may have not cured properly , the cycle is repeated to ensure that
the prosthesis is properly cured .
Tinytag Ultra 2 Thermocouple data loggers are compatible with K , J , T and N thermocouple sensors and can measure from -200 ° C to + 1370 ° C , offering fast response monitoring in high temperature applications .
