What is terahertz technology used for in wellness devices?太赫兹技术在健康理疗设备里是做什么用的？
Terahertz (THz) wellness devices use a purpose-formulated crystal or ceramic component, heated to emit in the 0.1–10 THz band alongside controlled thermal output. Manufacturers combine this with negative ion generation and smart temperature regulation in handheld and full-body devices.太赫兹健康理疗设备使用专门配方的水晶或陶瓷部件，在加热的同时发射0.1–10 THz波段。厂商通常还会在手持和全身设备中配合负离子发生和智能温控系统。
Does CareGear Tech support private-label and OEM manufacturing?CareGear Tech支持贴牌和OEM代工吗？
Yes. We support private-label packaging, regional exclusivity agreements, and tiered wholesale pricing for distributors, clinics, and wellness brands. See our packaging checklist article for what to plan for.支持。我们为经销商、诊所与健康品牌方提供贴牌包装定制、区域独家代理协议与阶梯批发价格。可以参考我们的包装清单文章了解具体要规划哪些事。

Is terahertz wave exposure safe?太赫兹波接触安全吗？
Terahertz waves are non-ionizing — the same broad category as the infrared warmth you feel from sunlight, well below the energy level of X-rays or other ionizing radiation. See our article on terahertz safety myths and facts for the full explanation.太赫兹波是非电离辐射——跟阳光带来的红外热量属于同一大类，能量水平远低于X射线等电离辐射。完整解释可以参考我们那篇太赫兹安全性误解与事实的文章。
Can I request a sample before placing a bulk order?批量下单前可以先要样品吗？
Yes, and we recommend it. A sample lets you verify noise level, heat consistency, and build quality before committing to a container-load order. See our sample-evaluation guide for a full checklist.可以，也建议这样做。样品能让你在下批量订单之前，先核实噪音水平、发热稳定性和做工质量。完整清单可以参考我们的样品评估指南。
What is the minimum order quantity (MOQ) for wholesale?批发的最小起订量（MOQ）是多少？
MOQ varies by product and by how much customization you need — private-label branding (custom packaging, colorway) generally has a lower MOQ than full ODM (custom mold/design). Submit an inquiry with your target product and market for a specific quote.MOQ因产品和定制程度不同而不同——贴牌（定制包装、配色）通常比全定制ODM（定制模具/外观）的MOQ门槛更低。提交询价单、注明目标产品和市场，我们会给出具体报价。
What is the difference between the DS-19 and DS-808 hot air devices?DS-19和DS-808这两款暖风仪有什么区别？
DS-19 adds wide-voltage support (110V/230V), negative ion output, and a smart touch interface. DS-808 covers the fundamentals at a more accessible price point — the two are designed to work together as a two-tier lineup.DS-19在宽频电压（110V/230V）、负离子输出和智能触控界面上更进一步。DS-808覆盖基础功能，价位更亲民——两款产品是刻意设计成两档梯度搭配使用的。
Do CareGear devices require direct skin contact?CareGear的设备需要直接接触皮肤吗？
It depends on the device. Handheld devices like the DS-19 are held close to the treatment area, while the BQTS Thermal Instrument and Thermal Sole are specifically designed to work directly over clothing or socks, with no skin contact required.因设备而异。DS-19这类手持设备是靠近治疗部位使用的，而BQTS光热理疗仪和Thermal Sole足部理疗器则是专为隔着衣物或袜子直接使用设计的，不需要接触皮肤。
What warranty do you offer, and how are defective units handled?你们提供什么质保？设备有缺陷怎么处理？
