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

Answer: In Bangladesh (BD), the regular market price for the Lovibond Comparator 2000+ base unit ranges between BDT 85,000 and BDT 110,000, depending on whether it is purchased as a standalone unit or bundled with specific color discs, Nessler tubes, and the Daylight Illuminating Unit. For official corporate price quotations, institutional tenders, and direct stock verification 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 Lovibond Comparator 2000+ comes standard with a 12-month (1-year) factory warranty covering housing integrity and optical prism defects. Authorized local suppliers like Federal Scientific Mart provide local technical support, replacement color discs, sample cells, Nessler tubes, spare daylight bulbs, and calibration validation across Bangladesh.

Q4: How does the prism optical system work in the Comparator 2000+?

Answer: The Comparator 2000+ incorporates a precision optical prism that merges light passing through the sample liquid and light passing through the colored glass disc into a single, adjacent split field of view. This side-by-side visual arrangement allows the operator's eye to easily match subtle hue intensity differences without visual distortion or edge effects.

Q5: What are the main applications and testing parameters available for this model?

Answer: The Comparator 2000+ is a versatile visual test system utilized across water treatment, chemical manufacturing, and food processing industries:

• Water & Wastewater Analysis: Testing Chlorine (free/total), pH, Fluoride, Iron, Ammonia, Phosphate, Nitrate, and Silica using standardized reagent chemical kits.

• Chemicals & Solvents: Evaluating color intensity in industrial chemical solutions, wastewater effluents, and process fluids.

• Petroleum & Oils: Grading color standards in refined oils and liquid chemical products using dedicated disc scales.

Q6: How do you operate and execute a color measurement test step-by-step?

Answer:

1. Insert the required Lovibond glass filter disc into the Comparator 2000+ disc housing.

2. Fill a clean sample cell or Nessler tube with your blank reference liquid and insert it into the left sample chamber slot.

3. Prepare the sample liquid with the appropriate test reagent, fill a second matching cell, and insert it into the right sample chamber slot.

4. Look through the eyepiece while holding the comparator up to a northern daylight source (or attach the optional Daylight Illuminating Unit).

5. Rotate the color disc until the glass filter color perfectly matches the reagent-reacted sample color in the split field of view.

6. Read the final parameter concentration or color value directly from the disc window display.

Q7: What is the advantage of using the optional Daylight Illuminating Unit?

Answer: Natural daylight varies significantly depending on time of day, weather, and room lighting. The optional Daylight Illuminating Unit clips directly onto the back of the Comparator 2000+, providing a constant, standardized light source (CIE Daylight) that eliminates ambient lighting variations and ensures repeatable, accurate color readings day or night.

Q8: How do you properly clean and maintain the Comparator 2000+?

Answer:

• Housing & Eyepiece: Wipe down the chemical-resistant plastic housing with a soft, damp cloth. Clean the optical eyepiece lenses with an antistatic optical tissue.

• Glass Discs & Cells: Keep color discs clean and free of fingerprints; store discs in their protective cases when not in use. Rinse sample tubes thoroughly with distilled water immediately after chemical testing to avoid staining.

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

Answer: The factory package includes:

• Lovibond Comparator 2000+ main body with optical eyepiece

• Set of sample cells / tubes (depending on specific kit configuration)

• Protective carrying case

• Instruction manual and factory quality compliance certificate (Note: Color discs, chemical reagents, and Daylight Illuminating Unit are ordered individually or selected as part of complete test kits).

Q10: Why purchase Lovibond equipment from Federal Scientific Mart (fsm.com.bd)?

Answer: Sourcing through Federal Scientific Mart guarantees:
