DDS-11A A type of conductivity meter is a laboratory conductivity measurement instrument. It can measure the conductivity of a general liquid, and can also measure high-purity water conductivity. There are 0 instruments ～10mV The signal output can be connected to an automatic electronic potentiometer for continuous recording.

Main technical features:

1、Measurement range: 0 ～105μs/cm（ That is, 0 ～100ms/cm）， Its equivalent resistivity range is ∞-10Ω·cm This range is divided into 12 ranges. Level 1.0, (0 ～20）ms/cm（ Divided into 5 ranges)

2、Basic error: (1) range (i.e. 0-0.1 μs/cm）≤2%，All other ranges ≤±1.5%
