FAQ's of Sink Type Blackbody Furnace for Calibration of Clinical Thermometer:
Q: How does the Sink Type Blackbody Furnace calibrate clinical thermometers?
A: Calibration is achieved by placing a standard clinical thermometer into the cavity of the high-conductivity copper block, which is coated with blackbody paint for optimal uniformity. The furnace rapidly stabilizes at the desired calibration temperature, verified by the internal precision platinum RTD. The thermometer reading is then compared to this set value for accuracy verification.
Q: What safety and control features does the furnace offer during operation?
A: The furnace features a digital PID controller for precise temperature management and includes built-in over-temperature protection. The digital LED display clearly presents real-time temperatures, and the system's stable set points minimize the risk of thermal drift, providing safe and reliable operation.
Q: When is this furnace most beneficial for laboratories or clinical use?
A: This equipment is essential whenever precise and standardized calibration of clinical thermometers is required, such as before routine medical device deployment, periodic quality control in calibration labs, or compliance verification per international standards like IS 3055 and ISO/IEC 17025.
Q: Where can the Sink Type Blackbody Furnace be installed?
A: Due to its compact benchtop design and moderate weight (approximately 15 kg), the furnace can be easily placed on laboratory benches or in calibration suites. It requires an ambient temperature between 5C and 40C and a stable 230V AC power supply for proper operation.
Q: What is the process for calibrating a single clinical thermometer with this system?
A: To calibrate, insert the thermometer into the 25 mm diameter cavity, set the target temperature within the 30C-50C range, and wait for less than 3 minutes for thermal stabilization. Once stable, compare the thermometer reading to the displayed value for calibration verification.
Q: What are the main benefits of using this blackbody furnace for thermometer calibration?
A: Users benefit from exceptional temperature uniformity (0.1C), high calibration accuracy (0.05C), rapid stabilization time, and conformity to stringent calibration standards. These features ensure accurate, repeatable calibrations critical in clinical and laboratory applications.
