2. STARTER 300C portable conductivity meter
STARTER 300C is a 0.5 level conductivity meter. Easy to operate and integrates multiple functions; It can be widely applied in various industries such as scientific research, environmental monitoring, food and beverage. Compliant with relevant Chinese standards and specifications (CMC license), CE certification, and production in accordance with ISO9001 standards. Our consistent pursuit is to provide you with products with better cost-effectiveness!
The accuracy of the conductivity meter is higher than the common 1.0 level conductivity meter in the market, and it is a 0.5 level product.
The standard four ring conductive electrode avoids errors caused by polarization and ensures accuracy in high salt solutions.
No need to input electrode constants, accurate measurement can be achieved after calibration with standard solution.
Conductivity measurement, TDS measurement, and salinity (only 3100C) measurement can be freely switched with one click.
The STARTER series of software with consistent style makes it easy for you to operate, and there is also a built-in quick browsing area (only 3100C) to help you use it.
