ACCURATE AND AFFORDABLE IRON MEASUREMENT

About 6.3% of the earths crust is made of iron, of which 43% is in soils. The analysis of iron 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 HI 721 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 721 Checker®HC is accurate and affordable with immediate results.  The new HI 721 Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm (5000 points) and ±2% of reading ±0.04 ppm accuracy. The HI 721 Checker®HC uses an adaptation of Standard Method 3500-Fe B.

The contoured style of this Checker®HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.  The HI 721 Checker®HC is extremely simple to use.  First, zero the instrument with your water sample.  Next, add the reagent. Last, Place the vial into the HI 721 Checker®HC, press the button and read the results. Yeah, it’s that easy!
