They are still manually operated. Therefore, the temperature of the developer is difficult to control and the quality of the tablet is not guaranteed. In order to solve this problem, the radiology department of our hospital developed a thermostat for the developer. Over the past three years, the use of the thermostat has been very effective. The quality of the tablet has been significantly improved. Now the structure, principle and production process are introduced as follows: l Structure The developer thermostat consists of two parts.
