我们的全硬度低量程手持式检查器®为您提供了先进仪器和典型化学测试试剂盒之间的中间地带。标准测试试剂盒的准确性有限，因为它们依赖人眼来匹配颜色。我们的手持式色度计通过提供直接的数字总硬度低范围结果，消除了与色卡匹配的麻烦。
- 范围：0至350 ppm（mg/L），以CaCO3计
- 一键操作，使用方便。
- 不要浪费时间匹配色卡，获得快速准确的数字结果。
- 适用于：饮用水和工艺用水、供暖和制冷系统、游泳池和水疗中心。
作为化学测试试剂盒的更好替代品，我们的总硬度低范围检查器®只需几个简单的步骤即可提供数字结果。
功能一览：
- 比化学测试试剂盒更简单、更准确
- 专用于单个参数
- 体积小，使用方便
