PH-2011
笔式酸度计产品规格：范围：0.00?14.00PH分辨率：0.01PH精度：±0.1PH电池：4×1.5V（AG-13）温度补偿：0℃?50℃工作温度：0℃?50℃尺寸：151mm×33mm×20mm重量：53克操作步骤1。取下保护盖2。先用蒸馏水清洗电极，并用滤纸吸干附在电极上的水分。3。接通位于电池仓上的开关。4。将PH计电极插入被测溶液中，直到液体浸到略底于“浸没线”处。5。轻轻搅动，待数值稳定，读取显示值。6。使用完毕，清洗电极，关掉开关，套上保护套。pH校准1。将PH电极浸入PH值为6.86（温度在25℃）的混合磷酸盐标准缓冲溶液中，轻轻摇动电极。2。用小起子调整电位器，直到显示值与标准缓冲溶液在环境温度下的PH值相符。
3。将PH电极浸入在PH4.01的磷苯二甲酸氢钾或PH9.18的硼砂标准缓冲溶液，轻轻摇动电极。
4。显示值与缓冲溶液的PH值相比应在误差允许范围内。
注意事项
在下列情况下，PH计必须重新校准。校准后已使用（或放置）很长时间电极使用特别频繁测量精度要求比较高。电池安装若背光亮度明显下降或显示值模糊，则应更换电池。更换电池时，拉出电池仓更换即可，注意电池的极性保修：本仪器从出厂之日起保修一年，担保由于生产和材料造成的缺陷。若在但保期间，仪器需要维修或更换，且造成损坏的原因，不是使用者的粗心大意或者使用不当，请将仪器及说明书寄给我们的代理或我们公司，我们将予已免费维修。
