pH255意大利哈纳HANNA pH255台式酸度计Acidity meter

是哈纳最新推出的一款高品质多参数测量仪器。使用这款仪器您可以同时测量样品的pH, TDS, ORP, 盐度和温度。进行酸度测量时，仪器自动进行温度补偿。仪器可以在5 个记忆点中选择1, 2或3 个校准点进行自动校准，从而保证测量值更精确。进行EC 测量是，仪器可在两个参考温度中（20°C 或25°C）选择并进行温度补偿。仪器会自动根据样品选择最合适的EC 及TDS 量程，同时EC 测量可以在6 个记忆点中选择1 点进行校准。HI255 具有可存储200 组测量数据的功能，所有存储的数据都可以通过RS232 接口输入电脑并可进行打印。HI255 还具有GLP 功能，所有的校准数据都可以按照用户意愿随时调出。
