This product is HI 93748 Manganese Low Range ISM, used to measure manganese level
The Hanna Instruments HI 93748 is a portable colorimeter designed to measure manganese content in water and wastewater within the 0 to 300 µg/L range. It utilizes an exclusive positive-locking system to ensure the cuvet is in the same position every time it is placed into the measurement cell, ensuring consistent results. The instrument features a light-emitting diode light source and a silicon photocell detector, operating via the adaptation of the PAN method where the reaction between manganese and reagents causes an orange tint in the sample.
This manual provides instructions for the preliminary examination of the instrument, the step-by-step measurement procedure, and details on required reagents and reagent sets. It also covers troubleshooting display codes, potential interferences from other metals, tips for accurate measurement, battery replacement, and a list of other accessories compatible with the device.
| Light Source | Light Emitting Diode @ 555 nm |
|---|---|
| Battery Type/Life | 7x 9 volt/40 hours |
| Dimensions | 180 x 83 x 46 mm |
| Weight | 290g |
The required reagents are HI 93748A-0 (Ascorbic acid), HI 93748B-0 (Alkaline cyanide sol), HI 93748C-0 (0.1% PAN indicator), and HI 93703-51 (Dispersing Agent).
This occurs when the cuvet is not inserted correctly or when excess ambient light is reaching the detector.
