Hanna Instruments HI 98129

pH/Conductivity/TDS Tester for low range EC measurement

Fast, efficient, accurate and portable! HANNA Instruments Combo Tester offers highly accurate pH, EC/ TDS and temperature measurements in one simple meter — NO more switching between meters! At start-up, the HI 98129 performs a self check then displays the remaining battery level to assure proper working condition. Includes an easy to read, LCD and an automatic shut-off.

The HI 98129 features a replaceable pH electrode as well as an EC/TDS graphite electrode, which resists contamination by salts and other substances. Warranty: 1-year (six months on electrode).

Unique Features:
• Rugged waterproof casing is designed to float!
• Automatic temperature compensation
• Display shows pH, EC, TDS and temperature
• Efficient two button operation
• Includes batteries, an electrode replacement tool and instructions

Size: 6.4″ tall x 1.6″ wide x 1.0″ deep

 

Grower’s Tip:

After use, rinse the electrode with water to minimize contamination and store it with a few drops of Electrode Storage Solution (HI 70300). Do NOT use distilled or deionized water for storage.

The Hanna Instruments HI 98129 pH/Conductivity/TDS Tester for low range EC measurement is a waterproof tester that offers high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements. The Hanna Instruments HI 98129 floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature compensated.

This tester features a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode. The extendable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted.

The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient (I2). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester combines all the features users have requested and more!
