Question 1

深圳市乐欣电子科技有限公司（百安途）主要做哪些产品？

Accepted Answer

乐欣电子科技（百安途）主营声级计、风速计、光照计、木材水份仪、电池检测仪、内阻仪，以及可燃气体检测仪、一氧化碳检测仪、甲醛检测仪等检测仪器仪表。

Question 2

声级计的 A 计权和 C 计权有什么区别，应该怎么选？

Accepted Answer

A 计权（dBA）对低频衰减较大，接近人耳感知特性，是环境噪声与职业噪声评价的通用计权方式；C 计权（dBC）对低频衰减小，适合机械噪声、冲压设备等低频成分丰富的声源。ET-958、ET-953 支持 A/C 计权一键切换，符合 IEC 61672-1 2 级标准，分辨率 0.1 dB。

Question 3

热式风速仪和叶轮式风速仪怎么选？

Accepted Answer

热式风速仪可检测 0.05~0.3 m/s 微弱气流，分辨率 0.01 m/s，适合洁净室、通风管道与室内空气质量评估；叶轮式结构耐用，测量范围 0.4~35 m/s，适合户外风速、风机性能与暖通出风口检测。ET-975P、ET-975 为热式方案，ET-95 为叶轮方案并内置温度补偿。

Question 4

四合一气体检测仪检测哪四种气体？报警阈值怎么设置？

Accepted Answer

标准四合一检测可燃气体（LEL）、氧气（O₂）、一氧化碳（CO）、硫化氢（H₂S）。常用阈值：可燃气低报 10% LEL、高报 25% LEL；氧气缺氧 19.5% VOL、富氧 23.5% VOL；一氧化碳 25/50 ppm；硫化氢 10/15 ppm。GD-100 支持多级报警阈值设置、声光振动三重报警、IP65 防护、续航 12 小时。

Question 5

针式、感应式、球型木材水分仪有什么区别？

Accepted Answer

针式（电阻式）精度高（±1%）但会留下针孔，适合原材料入库检验，MT-850 测量范围 2%~40%；感应式为无损检测，适合成品家具与地板抽检，ET-971 测量范围 3%~35%；球型探头接触面积大、读数稳定，MT-98 木材测量范围 5%~75%，建筑材料 0.1%~2.4%。室内家具用材含水率建议控制在 8%~12%。

Question 6

蓄电池内阻增大到多少需要更换？

Accepted Answer

判断依据是与电池自身基准值对比：内阻升到出厂基准值 1.5 倍时应重点关注，达到 2 倍时容量通常已降至 80% 以下，建议更换；组内某节偏离平均值 50% 以上也应重点监控。BT-100 采用四线（开尔文）交流注入法，内阻量程 0.01 mΩ~3000 mΩ，电压 0~600 V，可存储 10000 组数据。

Question 7

产品是否支持定制？

Accepted Answer

支持定制。可根据客户需求提供量程精度调整、功能拓展、外观标识、界面语言与报警阈值等 OEM/ODM 定制服务。

Question 8

是否可以提供样品？

Accepted Answer

可以提供样品，欢迎联系我们了解详情。

Question 9

产品的起订量是多少？

Accepted Answer

起订量根据具体产品而定，欢迎咨询获取详细信息。

Question 10

产品是否有质检报告或相关认证？

Accepted Answer

有符合各项产品的证书，可提供出厂校准报告，也可协助代送第三方计量机构出具 CNAS 校准证书。
