Product Description

ZDJ-5B automatic titrator supports potentiometric titration. The 7” color touch screen and navigation operation make the titration detection simple and convenient. It can support two sets of burettes (including a set of built-in burettes and a set of optional external burettes), which is more convenient for users who need to change the titrant frequently. The sampler realizes the automatic measurement of batch samples and meets the needs of customers for batch testing.
