产品名称:orp-2069 数显orp计
化电位。orp值是水溶液氧化还原能力的测量指标，其单位是mv。
orp计是测试溶液氧化还原电位的专用仪器。
带有背光显示，读数更清晰方便。
2069 orp计
是一款大屏幕带背光4位lcd笔试orp计，可供夜间使用，弥补了国内一些空白，是经典品牌的袖珍数显orp计，使用简便，稳定性及高，携带方便无需经常调节。
操作步骤
1.取下保护套。
2.打开位于电池仓上的开关，即接通电源。
3.将电极放入被测溶液中，轻轻晃动，待示值稳定后读取显示值。
4.使用完毕，关掉开关，用蒸馏水清洗电极，套上保护套。
校准
1.将orp计浸放蒸溜水中活化几小时。
2.将orp计插入256mv标准溶液（含醌氢醌试剂的4.01标准溶液）中，并轻轻摇动。
3.用小起子调整校正电位器，直到液晶显示为265毫伏。
4.用蒸馏水清洗电极。
注意：仪器电极需定期(15天左右)插入饱和氯化钾溶液中浸泡几个小时，以确保测量准确性。
