MARINE SALINITY TESTER HI98319

Designed to bring simplicity to salinity testing, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.) Comes with all the necessary solutions and batteries- everything you need to get started measuring right away. The included CR2032 Li-ion battery provides up to 100 hours of continuous use. The battery icon will blink to let you know it is time to change the battery so you never miss a measurement. Unlike stainless steel sensors, graphite sensors reduce polarization effects and does not oxidize for more reliable and accurate readings. Designed to withstand the knocks, drops, and spills of real life, the waterproof body ensures top performance in any environment. These meters are totally protected against dust and water intrusion f
