另一方面，考虑到成本和技术的原因，仍然有许多仪器采用LED数码管，显示内容不够丰富；
当然也有厂商通过一定途径弥补了这一缺点。目前比较多采用的方便操作的界面一般是LCD液晶显示+键盘式操作。
3、PH计常见误差的调整
温度是明显的造成PH误差的因数，有无温度探头，以及温度探头的灵敏度同样影响仪器的使用。
4、PH计稳定性
一台不稳定的酸度计读数困难，也很难保证仪器的准确性，稳定性表现在两方面，一方面是单台仪器的稳定性，可以将同一仪器长时间放置稳定溶液中，看数值是否变化及变化幅度；
另一方面的多台仪器的稳定性，将几台校验好的同一型号仪器放同一稳定溶液中看读数是否一致，误差有多少，如果几台同型号仪器之间不能保证稳定性，那就很难保证每台仪器的准确和稳定性。
