5052 Salinity meter for seawater

The Apera Instruments 5052 Salinity Meter is designed for easy and reliable salinity measurements in aquariums as well as in aquaculture and environmental monitoring. Apera Instruments’ unique platinum-coated electrode with automatic temperature compensation (ATC) ensures accuracy and precision of measurement results over a wide measurement range – an accuracy of ±1.5% F.S in the range 0 to 100 ppt (=100,000 ppm).

• Reliable salinity measurements in seawater (compared to hydrometer and refractometer). Sampling is not required. Simply immerse the meter in salt water and get stable readings in 10 seconds. No flushing required between each measurement.
• Regular calibration is not required – calibrating the meter once every month provides reliable results. The calibration solution is included in the set.
• The meter is equipped with a one-button operation and powered by 2 AAA batteries.
• Automatic power off and low battery reminder functions

The Apera Instruments 5052 Salinity Meter has a 2-year manufacturer’s warranty (6 months for electrodes).

Note: The Apera 5052 meter measures practical salinity (NOT absolute salinity), which is converted from conductivity using the Practical Salinity Scale 1978(PSS-78), and is standardized against normal standard seawater (S=35), which is accurately calibrated in conductivity ratio (K15). The PSS-78 is recommended by all oceanographic organizations as a benchmark for measuring salinity data.
