The HI 93730 is an instrument designed to measure molybdenum content in water and wastewater within a range of 0.0 to 40.0 mg/L (ppm). It utilizes the mercaptoacetic acid method, where the reaction between molybdenum and reagents creates a yellow tint in the sample for detection by a silicon photocell.
The manual details the measurement procedure involving specific reagents (HI 93730A-0, B-0, C-0) mixed with the sample. It also covers operational features such as auto-shut off after 10 minutes of non-use, battery replacement using a 9V alkaline battery, and troubleshooting display codes for errors like 'Under range' or 'Over range'.
| Range | 0.0 to 40.0 mg/L |
|---|---|
| Resolution | 0.1 mg/L |
| Accuracy | +/-0.3 mg/L +5% of reading |
| Light Source | LED @ 470 nm |
| Operating Temperature | 0 to 50°C (32 to 122°F) |
| Battery Type/Life | 1 x 9 volt/40 hours |

The meter measures molybdenum content in water and wastewater in the 0.0 to 40.0 mg/L (ppm) range.
A 9V alkaline battery is required, with a typical life of 40 hours.
Interference may be caused by Aluminum above 50 mg/L, Chromium above 1000 mg/L, Copper above 10 mg/L, and others.
