Product description

Portable Hanna HI 991301D meter for simultaneous pH and EC/TDS measurement with IP67 waterproof design.

The Hanna HI 991301D is a durable and waterproof portable meter designed for simultaneous pH and electrical conductivity (EC/TDS) measurements, ideal for field applications in biotechnology, molecular diagnostics, and water quality monitoring. Featuring an IP67 waterproof rating, this instrument withstands harsh environments commonly encountered in bioprocessing and environmental sample analysis. Key technical features include:

  • Simultaneous display of pH and EC (TDS) readings, improving efficiency in workflows like biomanufacturing monitoring.
  • Visualization of electrode status after calibration, ensuring reliable measurements essential for synthetic biology and molecular biology experiments.
  • Display of calibration standard buffer values on screen to confirm measurement accuracy during molecular diagnostics.
  • A pH-mV mode for evaluating electrode function by mV detection, critical for maintaining sensor performance in live-cell imaging and clinical applications.
  • Robust design with a waterproof quick DIN connector for electrodes facilitating ease of use and longevity in laboratory and field environments.

This portable meter is widely adopted in applications requiring precise pH and conductivity measurements such as bioprocess monitoring, environmental biotechnology studies, and quality control in pharmaceutical biomanufacturing.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
