HI-705 Silica Low Range Handheld Colorimeter - Checker®HC information
Hanna's extended description
Ideal for water quality testing
The HI-705 handheld checker is a simple, accurate, and cost effective way to measure low ranges of silica. Designed as a more accurate alternative to chemical test kits, the HI-705 provides quick, accurate results in four easy steps.
The HI-705 uses an adaptation of the ASTM D859 method of heteropoly blue method. The reaction between silica and reagents causes a blue tint in the sample.
Features/Benefits:
- Small palm-sized design
- Accurate from ±0.03ppm ± 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
- Environmental
- Water Treatment (Boilers/Cooling Towers)
