Q1: How does the distance indicator light work, and why is it important?
A1: The distance indicator light is a proactive accuracy tool. When you aim the thermometer, the light changes color or pattern once you are within the ideal measurement range. This ensures the infrared sensor collects data correctly, preventing errors caused by holding the device too close or too far, which is a common source of inaccurate readings in non-contact thermometers.
Q2: Is the one-second reading fast enough for screening a line of people, like at an office entrance?
A2: Absolutely. The one-second measurement speed is specifically engineered for high-throughput scenarios. It allows for rapid, efficient screening with minimal disruption to workflow. Combined with its hygienic non-contact operation, it makes the DET-3019A an excellent choice for public health screening and institutional use, helping to maintain a safe environment without creating bottlenecks.
Q3: Can I turn off the beep sound for use in a quiet room, like a nursery?
A3: Yes, the auditory feedback is flexible. While the standard model uses a beep, you can opt for the vibration alert module as an alternative. This provides a silent, discreet confirmation that the measurement is complete, perfect for checking a sleeping child, in libraries, meetings, or any setting where noise should be minimized.
