Model 30 portable conductivity meter

• suitable for salinity measurement of various water bodies, it is the best companion for conductivity test of seawater / salt water; It can be used for routine conductivity measurement in laboratory or field; Another 30m type can store 50 groups of readings. It can be converted into chloride content according to salinity

• four pure nickel electrode probe is adopted, with high accuracy and small maintenance, without platinum black plating. No calibration required: the instrument has been pre calibrated before leaving the factory, and can be read after startup

• it has the functions of automatic range switching and automatic temperature compensation. Full battery operation, working life up to 100 hours (alkaline battery). Low battery display

• it adopts a solid waterproof shell, which is suitable for the harsh environment in the wild. Even if the instrument falls into the water, it can float automatically; The probe is equipped with a stainless steel sleeve, which is durable and easy to sink into the water
