AK115 AK115 Max - Portable EC/TDS/Salinity Meter

Portable, precise, accurate Measurements

The built-in microprocessor enables advanced functions, such as automatic calibration, automatic temperature compensation, self-diagnosis, auto power-off, and low-battery indicator, and improves the response time and accuracy of your measurements.

The MAX portable Conductivity/TDS/Salinity/Temperature meter is water resistant (IP65) and feature a large LCD display that provides simultaneous Conductivity and temperature readings with a resolution of 0.1 µS and an accuracy of ± 2% Full scale. Conductivity probe with integrated temperature sensor. 5 points automatic calibration and extended range up to 150.0 mS.

Ideal for quick, accurate checks in laboratories and schools, the AK115 is also used for analysing water in pools, lithographic processes, boiler and cooling tower, aquaculture, aquarium and nutrients levels in Hydroponics.

Applications

Built for the field

Aquaculture

Monitor water quality in ponds, tanks, and hatcheries for optimal fish and shrimp health.

Laboratory

Bench-grade accuracy for QC, research, and routine laboratory analysis.

Water Treatment

Field testing for municipal and industrial water treatment monitoring.

Hydroponics

Swimming Pools

Aquariums

Keep display and breeding tanks stable — pH, ammonia, nitrite and dissolved oxygen.

Horticulture

Nutrient solution and irrigation water control for greenhouse and field growing — EC, TDS and pH.
