透明无色pH校正液/标准液,适合任何品牌pH计―上海金山科研平台
pH计使用过一段时间后都要重新调校,时间取决于所测溶液和使用频率。使用一段时间后,工业在线pH计电极不对称,电位将会发生很大改变,故须定期校准。
pH计标定校准的次数取决于试样、工业在线pH计ph电极性能及对测量的精确度要求。高精度测量(≤±0103pH) ,应及时校准;一般精度测量( ≤±011pH) ,经过一次校准后可连续使用两周甚至更长时间。只要测量显示pH值是准确的,就没必要频繁对ph电极进行标定。
先测试与被测溶液较接近的标准溶液,根据误差大小,确定是否需要重新校准。在下列情况下必须重新校准:
l 更换新的工业在线pH计电极。
l 工业在线pH计测量浓酸液(pH < 2) 以后,或测量浓碱液(pH > 12) 以后。
l 工业在线pH计测量含有氟化物的溶液或较浓的有机溶液后。
l 被测溶液温度与标准溶液温度(或室温)相差过大时。
上海金山科研平台生物提供适合任何品牌pH计pH校准液/标准液。
