Product description

Multi-parameter benchtop meter measuring pH, conductivity, DO, ORP, and ISE with data logging & USB export.

The Hach HQ440d Benchtop Multi-Parameter Meter is engineered for precise and versatile laboratory water quality analysis, essential in *molecular diagnostics*, *bioprocessing*, and *environmental biotechnology* workflows. This advanced instrument simultaneously measures critical parameters including:

  • pH (0–14 range) with automatic temperature compensation
  • Conductivity (0.01 µS/cm to 200.0 mS/cm)
  • Optical Dissolved Oxygen (DO) (0.1–20.0 mg/L) with optical sensor technology
  • Oxidation-Reduction Potential (ORP)
  • Ion Selective Electrode (ISE) measurements for ions such as ammonia and chloride

Key features include a high-resolution backlit LCD (440 x 160 pixels) for clear data visualization and an IP54 rating, providing robust protection against dust and water spray, suitable for demanding laboratory and pilot plant environments. The integrated GLP-compliant data storage records up to 500 measurement logs, supporting compliance with quality assurance protocols common in *biomanufacturing* and *synthetic biology* research.

Data export is streamlined via the built-in USB interface, enabling seamless integration with laboratory information management systems (LIMS) commonly used in *cell imaging* and *biomedical engineering* research. Multilingual support and selectable calibration intervals (2 hours to 7 days) enhance usability across diverse biotechnological applications.

Widely adopted in *water quality monitoring* within *clinical diagnostics* and *bioprocessing pipelines*, the HQ440d meter provides reliable, comprehensive analytical capability for laboratories conducting live-cell culture media assessment, buffer solution validation, and environmental sample analysis.

This benchtop multi-parameter meter is a critical tool for researchers requiring high precision in chemical analysis workflows, combining versatile parameter measurement with data integrity and durability.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
