(fresh) - COMPLETELY SUBMERSIBLE! Use the readings to re-create your fishes' natural environment: low ppm for tetras, angels & discus and high ppm for mollies, cichlids & goldfish. The new waterproof (they even float!) tester has a dual-level LCD that displays EC or TDS and °C or °F. At startup, Tester performs a self check then displays the remaining battery level to assure proper working condition. These testers also feature a stability indicator and hold feature to prompt the user when to take the reading & freeze the display for easy and accurate recording. This new EC / TDS / Temperature meter has a stainless steel temperature probe for faster and more precise temperature measurement. Calibration and temperature compensation is automatic, while the EC / TDS conversion factor and temperature coefficient factor (ß) are user adjustable for application specific measurements. This advanced EC / TDS / °C / °F meter features graphite electrode to provide the greatest possible accuracy as it cannot be contaminated by salt deposits in the solution and when the electrode finally is exhausted simply insert a new electrode cartridge!
