服务案例
市政污水处理 · 汉钠现货配置案例
项目概况
项目现场在城市污水处理厂的进水、生化与出水工段。客户希望在既有装置上完善汉钠配置，核心诉求是以 Hanna 系列仪器覆盖便携与实验室水质检测。
技术难点
真正麻烦的是：污水中含固率高、含腐蚀性组分，昼夜水量波动大，并且出水指标波动、探头易被污泥与生物膜覆盖。这些都要求汉钠在配置时按参数组合、精度与现场便携性选型。
配置方案
按现货中心组织供货与实施：从现货库存中直接配置并快速交付。现场按参数组合、精度与现场便携性选型，并逐条核对：出水须稳定达到一级 A 标准并联网上传数据。
投运表现
完成调试后，现场即可出结果，实验室复核量下降，测量数据可直接用于工艺调整与考核。
食品饮料 · 汉钠现货配置案例
现场工况
该客户属于食品饮料行业，生产装置位于配料、杀菌、灌装与 CIP 清洗工段。项目的主要任务就是以 Hanna 系列仪器覆盖便携与实验室水质检测。
需要解决的问题
难点在于介质多为糖浆、乳品与饮料等易结垢物料，卫生级要求高；与此同时清洗频繁，仪表必须耐受 CIP/SIP 高温碱洗。选型上必须按参数组合、精度与现场便携性选型。
我们的做法
我们采用现货中心的交付思路 — 从现货库存中直接配置并快速交付。实施时按参数组合、精度与现场便携性选型，同时逐项校验：须满足食品安全与卫生级（3-A / EHEDG）要求。
运行结果
系统投运以来表现稳定，日常维护量明显减少 — 现场即可出结果，实验室复核量下降。
化工制药 · 汉钠现货配置案例
应用背景
反应釜、计量罐与成品储罐区是化工制药行业的典型工况。项目以汉钠为切入点，重点是以 Hanna 系列仪器覆盖便携与实验室水质检测。
工况约束
强腐蚀与防爆双重约束，仪表寿命短、停机维护成本高，而介质腐蚀性强、常带溶剂与结晶，部分区域为爆炸性环境的条件又进一步放大了这一点。因此汉钠必须按参数组合、精度与现场便携性选型。
交付方案
交付按现货中心来组织 — 从现货库存中直接配置并快速交付。实施中按参数组合、精度与现场便携性选型，同时满足需满足防爆认证与 GMP 数据可追溯要求。
使用效果
运行结果表明：现场即可出结果，实验室复核量下降，该测点的测量置信度明显提高。
电力能源 · 汉钠现货配置案例
客户情况
电力能源行业的典型场景是锅炉给水、汽机凝结水与脱硫脱硝系统。本次测量对象为汉钠，工作重点是：以 Hanna 系列仪器覆盖便携与实验室水质检测。
面临的难点
现场工况为高温高压，蒸汽与含盐水并存，加上高温高压下测量漂移，非计划停机代价极高，常规配置很难长期胜任。方案需要按参数组合、精度与现场便携性选型。
实施方式
方案由现货中心落地：从现货库存中直接配置并快速交付。技术要点在于按参数组合、精度与现场便携性选型，并确保符合：需满足电力行业规程与机组可用率指标。
客户收益
实际效果上，现场即可出结果，实验室复核量下降，现场运维人员的工作负担随之下降。
