Handheld Colorimeters


• Easier to use and more accurate than chemical test kits


• Dedicated to a single parameter


• Small size, big convenience


• Ideal for:


· Industrial ground and treated waters
· Mining leachate monitoring
· Agricultural irrigation water
· Pools and spas

About 6.3% of the earth’s crust is made of iron, of which 43% is in soils. The analysis ofiron is often performed to monitor ground water and irrigation waters as a gauge of corrosion from industrial settling, and as an indication of the effectiveness of treatment from mining leachate.

 

The Hanna HI746, HI721, and HI7214 Checker®HC bridge the gap between simple chemical test kits and professional
instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points of resolution, while professional
instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. These meters are accurate,affordable, and produce immediate results.

 

The HI721 and HI7214 features a resolution of 0.01 ppm and ±0.04 ppm ±2% of reading accuracy while the HI746 features 1 ppb resolution and ±20 ppb ±5% of reading accuracy. The contoured style of these meters fit in
your palm or pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures battery life will not be drained if you forget to turn it off.
