Q2: What is the price and local procurement procedure in Bangladesh (BD)?

Answer: In Bangladesh (BD), the regular market price for the Hanna HI98130 High-Range Combo Tester typically ranges between BDT 25,000 and BDT 28,000, depending on current import duties, included calibration sachet kits, and local supplier warranties. For official corporate price quotes, institutional tenders, and direct stock availability in BD, contact authorized laboratory distributors such as Federal Scientific Mart (fsm.com.bd).

Q3: What warranty coverage and technical support are provided in Bangladesh?

Answer: The Hanna HI98130 main instrument body comes standard with a 12-month (1-year) factory warranty covering meter electronic defects and internal circuit board faults, while the replaceable HI73127 pH electrode carries a 6-month warranty. Authorized local suppliers like Federal Scientific Mart provide local technical support, replacement electrodes, spare battery sets, calibration buffer solutions, and maintenance guidance across Bangladesh.

Q4: What is the main difference between the Hanna HI98129 and HI98130 models?

Answer: Both meters share the same waterproof housing, pH range, and dual-level LCD, but differ in EC and TDS measurement ranges:

• HI98129 (Low Range): Measures EC from 0 to 3999 uS/cm and TDS from 0 to 2000 ppm (mg/L). Ideal for clean drinking water, hydroponics, and low-salinity samples.

• HI98130 (High Range): Measures EC from 0.00 to 20.00 mS/cm and TDS from 0.00 to 10.00 ppt (g/L). Engineered for industrial wastewater, brackish water, high-concentration nutrient solutions, and agricultural drainage.

Q5: How does the replaceable pH electrode cartridge (HI73127) extend instrument lifespan?

Answer: Standard pocket testers must be completely discarded when the glass bulb or reference junction ages out or gets damaged. The HI98130 features a modular HI73127 replaceable electrode cartridge secured by a durable stainless steel round connector. When the pH sensor reaches the end of its operational life, users can simply unscrew the old electrode and plug in a new HI73127 cartridge without replacing the entire meter, significantly lowering long-term maintenance costs.

Q6: Which primary applications and industries benefit from using the HI98130?

Answer: The HI98130 is designed for field and laboratory multi-parameter water testing across diverse sectors:

• Wastewater & Industrial Effluents: Monitoring high-salinity discharge and industrial processing water.

• Agriculture & Commercial Hydroponics: Checking high-concentration fertilizer stock solutions and runoff water.

• Aquaculture & Fish Farming: Measuring salinity, total dissolved solids, and pH in brackish or marine environments.

• Boiler & Cooling Towers: Evaluating mineral concentration and water quality parameters in thermal systems.

Q7: How do you calibrate and operate the HI98130 step-by-step?

Answer:

1. Power On: Press the MODE button to turn on the meter and check the battery percentage indicator.

2. pH Calibration: Submerge the sensor in pH 7.01 buffer solution, enter calibration mode (CAL), wait for stability confirmation, then repeat with pH 4.01 or 10.01 buffer.

3. EC/TDS Calibration: Rinse the probe with distilled water and submerge it in 12.88 mS/cm EC calibration solution (or 6.44 ppt TDS solution) until the meter confirms calibration.

4. Taking Measurements: Dip the probe into your fluid sample, swirl gently, and read the pH, EC, or TDS values alongside live temperature directly on the LCD screen once the stability tag disappears.

Q8: How do you properly clean, store, and maintain the HI98130 sensor?

Answer:

• Storage: Keep the pH bulb moist by placing a few drops of HI70300 Storage Solution (or pH 4.01 buffer) inside the protective cap. Never store the probe in distilled or deionized water.

• Cleaning: Rinse the graphite EC/TDS sensor and pH glass bulb with distilled water after every use. For stubborn oil or mineral residue, soak the probe tip in HI700601 General Purpose Cleaning Solution for 20 minutes before rinsing and recalibrating.

• Graphite EC Pins: Clean the exposed graphite EC pins periodically with a soft brush to prevent salt crust buildup.

Q9: What items are included in the standard factory package when purchased?

Answer: The complete factory package includes:

• Hanna HI98130 Combo Tester main unit
