About This

• 【Material】Square salinity hydrometer is made of high-quality acrylic material, with high light transmittance, sturdiness and durability, and long service life.
• 【Description】Based on the internal reading of the scale, based on the salinity of the horizontal scale (PPT). The recommended ratio of water in a tank is between 1,020 and 1,023 (safe range).
• 【Package】The package contains a square salinity meter. The length of the product is about 12 cm/4.7", the width is about 9 cm/3.5", and the thickness is about 1.5 cm.
• 【Advantage】Insert the hydrometer to the water tank or fish pond below 15 cm, until the water overflows the baffle, and rinse with water in time after use.
• 【Application】Square salinity hydrometer is suitable for 20-30℃ warm water, temperature changes will cause the reading to change, and the unit specific gravity is accurate to ± 0.001.
