Durable clear plastic hydrometer. Accurate and easy to read. Designed for use in warm water aquariums (18-28C). Readings are temperature-corrected & accurate to +/- 0. 002 specific gravity units which range from 1. 010 - 1. 030 specific gravity. 16-40 salinity ppt. It is optimum to be put into below 6" deep water, so it can avoid the error from the oil slick.

Measurements of ORP are fundamental to water and liquid quality, and this pocket ORP meteroffer high reliability and accuracy at a very affordable price. It measure theamount of Oxidation Reduction Potential (ORP) level in a solution. ORP is a tendencyof the solution to either gain or lose electrons. Oxidation is definedas the loss of electrons in a molecule, atom or ion. An oxidizing agent (e.g.Chlorine and Ozone) is a substance that acquires electrons in a Redox reaction.ORP is a potential which is measured in millivolts (mV). The more positive theORP value, the greater the power of water disinfection, thus the faster the microorganismis killed (oxidized). ORP or Oxidation Reduction Potentialis commonly used in measurement of Water Disinfection and is correlated with thequality and purity of water. This meter allows calibration and offers highly reliablemeasurements and has a wide range of applications in Aquarium, Hydroponics, Spas,Swimming pools and other water systems.

An essential piece of equipment for every marine aquarium keeper. Measures the salt saturation of water (specific gravity of the water.) Basically - it describes the weight of dissolved salt in the water. When the hydrometer is used regularly in saltwater aquariums, it ensures salinity and specific gravity are in balance - helps to ensure the health of the fish in the aquarium.
