AI Item Analysis

·AI can make mistakes·Verify before acting
The item is a Welch Allyn SureTemp Plus 690 electronic thermometer, designed for clinical use. It is primarily constructed from white plastic, with a smooth, matte finish. The device features a prominent rectangular digital display screen near the top, which appears to be blank in the image, suggesting it may be off or not actively in use. Below the screen, there are three oval-shaped buttons, two of which are light blue and one darker blue, indicating different functions. The brand name "Welch Allyn" is printed in green text above the display, and "SureTemp Plus" is printed in black below it. A notable feature is the light blue, flexible, coiled cord extending from the top, connecting to a probe tip, which is likely used for temperature measurement. The bottom portion of the thermometer's handle has a textured, light teal/green grip area, designed for ergonomic handling. The overall condition appears to be good, with no visible signs of significant wear, cracks, or discoloration. It rests on what appears to be a white counter or tabletop, and a white box with a barcode is visible directly beneath it, likely containing probe covers or accessories. Part of a black tube, possibly from a blood pressure cuff, is also visible in the foreground, suggesting a medical examination setting. The design is characteristic of modern medical diagnostic equipment, likely from the late 20th or early 21st century.

AI Appraisal Report

·AI can make mistakes·Verify before acting
I have thoroughly examined the provided image of this Welch Allyn SureTemp Plus 690 electronic thermometer. Based on visual inspection, the item appears to be in good to very good condition. The white plastic casing shows no visible signs of significant wear, cracks, or discoloration. The notable features, such as the digital display, the three oval buttons (two light blue, one darker blue), the coiled cord, and the textured teal/green grip, all appear intact and consistent with the manufacturer's design. The brand name 'Welch Allyn' and 'SureTemp Plus' are clearly legible, indicating authenticity based on branding. Market conditions for used medical diagnostic equipment like this thermometer are generally stable, driven by the needs of small clinics, veterinary practices, and home healthcare settings. Comparables for the SureTemp Plus 690 often range from $75 to $200 on secondary markets, depending on condition, included accessories (such as the probe and any base unit), and functionality. This model is well-known and widely used, meaning demand is consistent but not indicative of rarity. The primary factors impacting value for this specific unit are its apparent good cosmetic condition and the presence of the probe and coiled cord. The blank display suggests it may be off, which is not concerning, but a functioning display and accurate temperature readings are crucial for full value. The white box beneath it, likely containing probe covers, adds a minor value. Limitations in authenticity verification from an image alone are significant. While the branding appears correct, I cannot verify the internal electronics, battery health, or accuracy of the temperature readings. A full in-person examination would require powering on the device to check the digital display's functionality, testing its accuracy against a known standard, checking all button responses, and inspecting the probe tip for any damage or wear not visible in the photo. Provenance documentation, such as service records or original purchase receipts, would further confirm its authenticity and operational history. Without these, the appraisal remains largely based on external cosmetic condition and assumed functionality.
