The Hanna Checker® 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 Checker® is both accurate and affordable.
The HI720 Checker®HC (Handheld Colorimeter) is a simple, accurate, and cost effective way to measure calcium. Designed as a more accurate alternative to chemical test kits, the HI720 provides quick, accurate results in four easy steps:
| Weight | 1 kg |
|---|---|
| Parameter | Hardness |
| SKU | HI720 |
| Name | Calcium Hardness Checker® HC |
| Hardness, Calcium Range | 0.00 to 2.70 ppm |
| Hardness, Calcium Resolution | 0.01 ppm |
| Hardness, Calcium Accuracy | ±5% of reading ± 0.20 ppm |
| Hardness, Calcium Method | adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Calmagite method. The reaction between calcium and reagents causes a reddish-violet tint in the sample. |
