Max - Portable Optical Dissolved Oxygen Meter
Portable dissolved oxygen and temperature meter with a low-maintenance optical probe for aquaculture and environmental monitoring.
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 Dissolved Oxygen/Temperature meter is water resistant (IP65) and feature a large LCD display that provides simultaneous D.O. and temperature readings with a resolution of 0.01 mg/L and an accuracy of ± 0.3mg/L (0 a 10.00 mg/L).
The AK1030 Optical probe with built-in temperature sensor, means accurate measurements, holds calibration longer, no stirring required, no probe or membranes to clean.
Optical dissolved oxygen sensors combine precise measurement with low maintenance to monitor the dissolved oxygen level water applications. The AK121 MAX is ideal for Aquaculture and Environmental applications.
Applications
Monitor water quality in ponds, tanks, and hatcheries for optimal fish and shrimp health.
Keep display and breeding tanks stable — pH, ammonia, nitrite and dissolved oxygen.
