This document is the instruction manual for the HI 96742 Ion Selective Meter, describing the features and characteristics of the product.
This document is an instruction manual for the Hanna Instruments HI-96742 Ion Selective Meter. The device measures Iron Low Range (LR) and Manganese LR concentrations using specific reagents and methods (TPTZ and PAN). It features a liquid crystal display, automatic shut-off, and includes instructions for zeroing, reading samples, and performing validation or calibration procedures using Hanna CAL CHECK standards.
The manual details the functional description of the keys, including RANGE/GLP/A, CAL CHECK, ZERO/CFM, READ/M>/TIMER, and ON/OFF. It provides step-by-step guides for measurement procedures, error handling (such as Light High/Low or Battery low), and troubleshooting common issues like inverted cuvettes or over-range conditions.
| Range (Iron LR) | 0.00 to 1.60 mg/l |
|---|---|
| Range (Manganese LR) | 0 to 300 µg/t |
| Accuracy (Iron LR) | +/-0.01 mg/l +5% of reading @ 25°C |
| Accuracy (Manganese LR) | +/-2 µg/L +/-3% of reading @ 25°C |
| Resolution (Iron LR) | 0.01 mg/l |
| Resolution (Manganese LR) | 1 µg/t |
| Light Source | Silicon Photocell with narrow band interference filter @ 650 nm |
| Operating Temperature | 0 to 50°C (82 to 122°F) |
| Dimensions | 192 x 104x 69 mm |
The instrument uses the TPTZ method, where the reaction between iron and the reagent causes a violet tint in the sample.
The instrument uses the PAN Method, where the reaction between manganese and the reagents causes an orange tint in the sample.
There is too much light to perform a measurement; you should check the preparation of the zero cuvette.
The concentration of the sample is beyond the programmed range, and you should dilute the sample and re-run the test.
