一般的离子计只能测出电极电位或Px值,只有带微处理机的离子计才能直读浓度。这类仪器如奥尼龙公司的901离子计和国产的SL-2型离子计,尚不能在基层普及。为发挥现有仪器的作用又能达到直读浓度及含量的目的,我们采用广州8031计算器与其配合,可在直线电位法、标准加入法和样品加入法中直读浓度或含量。除广州8031计算器外,其它带有公式储存的计算器也可使用。
General ionometer can only measure the electrode potential or Px value, only the ion meter with a microprocessor can directly read the concentration. Such instruments as the 901 ion meter O’Neil company and domestic SL-2-type ion meter, still can not be popularized at the grassroots level. To play the role of existing instruments and can achieve the purpose of direct reading concentration and content, we use the Guangzhou 8031 calculator with it, in the linear potentiometry, standard addition method and sample addition method directly read the concentration or content. In addition to the Guangzhou 8031 calculator, other calculator with formula storage can also be used.
