About the HI-83303 Aquaculture Photometer with pH meter
Advanced optical system - Unparalleled performance from a benchtop photometer
One meter can be used for both photometric and pH measurements. The meter has 20 different programmed methods measuring 12 key water quality parameters and also offers an absorbance measurement mode for performance verification and for users who would like to develop their own concentration versus absorbance curves. To save valuable benchtop space, the HI-83303 doubles as a professional pH meter with its digital pH/temperature electrode input. Aquaculture parameters include Alkalinity, Calcium, Nitrite, and Phosphate which are critical to maintaining a healthy system. It also contains parameters specific to either a marine or freshwater environment.
The HI-83303 offers an absorbance measuring mode that allows for CAL Check standards to be used to validate the performance of the system. The absorbance mode allows the user to select one of the five wavelengths of light (420 nm, 466 nm, 525 nm, 575 nm, and 610 nm) to measure and plot their own concentration versus absorbance mode.
