声级计的 A 计权和 C 计权有什么区别，应该怎么选？

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。

热式风速仪和叶轮式风速仪怎么选？

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。

四合一气体检测仪检测哪四种气体？报警阈值怎么设置？

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。

针式、感应式、球型木材水分仪有什么区别？

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%。

蓄电池内阻增大到多少需要更换？

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。

产品是否支持定制？

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。

Toxic Gas Safety Monitoring in Chemical Industrial Parks

Project Background

Hazardous gases such as hydrogen sulfide and ammonia may be generated during chemical park operations. Regular monitoring of gas concentrations in the work environment is required to ensure personnel safety.

Facing Challenges

Wide detection coverage with scattered monitoring points
There are many types of toxic gases.
Respond quickly to leak incidents
Harsh environments demand high instrument standards.

Solutions

Use GD-100 to monitor gas concentrations in critical production areas and patrol routes. Establish a daily inspection system; immediately activate emergency response protocols and locate leak sources if levels exceed limits.
