ARKA - 9133 Aräometer Density Meter with Thermometer for Any Sea Water Aquarium, Safe and Easy to Use, Also Suitable Laboratory One Size

Density meter for saltwater – The ARKA hydrometer determines density and salinity in the saltwater aquarium quickly and precisely. For stable water values and control of salinity during day-to-day running. With integrated thermometer – Measuring range density 1.018 to 1.028 at a resolution of 0.0001, temperature 8 to 35 °C. Recommended range 1.022 to 1.024 at 25 °C, marked green on the scale. Easy to use – The hydrometer is used free-floating in a large vessel at the recommended temperature of 25 °C and read at the waterline. Note the scale for temperature-related deviation. Lab quality from France – Made in France to strict quality standards with high measuring accuracy, maximum deviation +/- 0.0002 at 25 °C. For regular checking of sensitive parameters. Combines with a measuring cylinder – For comfortable measuring, we suggest a suitable vessel such as the ARKA measuring cylinder of borosilicate glass 3.3, so density readings stay clean and controlled.
