needs to be tested regularly to ensure that it remains to be a healthy environment for the aquatic life it carries. Such tests include checking the pH levels, the temperature, electrical conductivity (EC), total dissolved salts (TDS), etc. Needing one device for each test makes the task very tedious, but lucky for you, there is a device that can measure all those mentioned, and that device is the Hanna instruments Combo PH/EC/TDS/Temperature Tester with Low Range EC from Pet Store
First off, this tester is waterproof so it can be submerged in water to get the necessary readings. It is also quit easy to hold, with its textured grip casings. Upon switching on the tester, you can easily check how much battery power you still have left, expressed as a percentage. Temperature readings are expressed in Celsius or Fahrenheit - simply set it according to your preference.
For pH readings, this tester is equipped with a removable cartridge which can be replaced if the sensor is already all used up. You don't have to replace the whole tester - just the cartridge.
The user interface is straightforward -- it has a clear digital screen and only two buttons. Even if you are technology-challenged, this tester shouldn't intimidate you one bit.
The HI 98129 Combo waterproof tester offer high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-level LCD and automatic shut-off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). This technologically advanced tester has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances. This gives these meters a greatly extended life. Your tester no longer needs to be thrown away when the pH sensor is exhausted.
The EC/TDS conversion factor is user selectable as is the temperature compensation coefficient (ß). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester brings you all the features you`ve asked for and more!
