Pocket Conductivity Meter
Pocket EC and temperature tester with 2-point automatic calibration and ATC for water treatment, food, horticulture and hydroponics.
Robust, for accurate and fast measurements.
The AK51 Tester is a practical and versatile instrument suitable to monitor Conductivity and temperature in a variety of applications: wastewater treatment, Food and beverage industry, Horticulture, Hydroponics, Agriculture, Swimming Pools, lithographic processes, boiler and cooling tower, aquaculture, aquarium and brewing. The automatic calibration in 2 points and its easy-to-use interface, makes the AK51 a simple and accurate instrument with readings you can trust.
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.
Ideal for quick, accurate checks in the field, the AK51 is also used for analysing water in pools, lithographic processes, boiler and cooling tower, wastewater, aquaculture, aquarium and nutrients levels in Hydroponics.
Applications
Monitor water quality in ponds, tanks, and hatcheries for optimal fish and shrimp health.
Rapid checks for dairy, beverages, sauces, and process-line compliance.
Field testing for municipal and industrial water treatment monitoring.
Keep display and breeding tanks stable — pH, ammonia, nitrite and dissolved oxygen.
Nutrient solution and irrigation water control for greenhouse and field growing — EC, TDS and pH.
