This manual is the instruction manual for Hanna HI 96721 Iron High Range ISM, which introduces the features and usage methods of the instrument.
The HI 96721 is an auto diagnostic portable microprocessor meter designed to measure total iron (Fe) content in water samples within a range of 0.00 to 5.00 mg/L. It utilizes an advanced optical system based on a special tungsten lamp and a narrow band interference filter at 525 nm, adhering to USEPA Method 315B and Standard Method 3500-Fe B.

| Accuracy | ±0.04 mg/L ± 2% of reading @ 25°C |
| Light Source | Tungsten lamp |
| Light Detector | Silicon Photocell with narrow band interference filter @ 525 nm |
| Environment Temperature | 0 to 50°C (32 to 122°F) |
| Battery Type | 1 x 9 volt |
| Dimensions | 192 x 102 x 67 mm (7.6 x 4 x 2.6") |
| Weight | 290 g (10 oz.) |
The meter measures total iron content in water samples in the 0.00 to 5.00 mg/L (ppm) range.
The method is an adaptation of USEPA Method 315B for natural and treated waters, and Standard Method 3500-Fe B for water and wastewater.
The meter turns off after 10 minutes of non-use in measurement mode or after 1 hour if left in calibration mode.
