Freshwater Alkalinity Colorimeter - Checker HC

Ideal for fresh water aquariums (not suitable for salt water marine tanks)

Designed as a more accurate alternative to chemical test kits, it is easy to use with single button operation and a large LCD display. This mini tester also features auto shut-off to ensure a longer battery life.

The HI-775 is ideal for checking water quality, great for educational and environmental applications and for use in freshwater aquaria.

Designed as a more accurate alternative to chemical test kits, the HI-775 provides quick, accurate results in four easy steps. (See below).

The HI-775 uses a colorimetric method. The reaction causes a distinctive range of colours from yellow to blue to develop. This meter has been developed to work with fresh water samples.

Please note: Any chlorine present in the sample will interfere with the reading. To remove the chlorine interference add one drop of HI-93755-53 Chlorine Remover to the unreacted sample prior to testing.

Features:

• Small palm-sized design
• Accurate from ±5ppm ± 5% of reading
• Dedicated to a single parameter
• Uses a single AAA battery
• Auto Power Off after 10 minutes in inactivity
• Built-in timer for timed reaction readings

Ideal for:

• Water Quality
• Education
• Freshwater Aquarium
• Environmental
