Product description

Benchtop conductivity meter with 6.5" LCD, automatic temperature compensation, and 1000-record memory.

The Ohaus AquaSearcher AB33EC is a precision benchtop conductivity meter designed for laboratory measurement of conductivity, total dissolved solids (TDS), salinity, and resistivity. Featuring a user-friendly 6.5-inch LCD display with a touch keypad interface, it enables efficient setup, calibration, and parameter adjustments during routine testing workflows.

Key technical specifications include:

  • Selectable reference temperatures at 20°C or 25°C to align with common laboratory standards.
  • Automatic temperature compensation for consistent conductivity readings across varying sample conditions.
  • Compatibility with both 2-cell and 4-cell conductivity probes, supporting versatile electrochemical sensor options.
  • Adjustable TDS factor settings to tailor measurements to specific sample needs, enhancing accuracy in molecular diagnostics and bioprocess monitoring.
  • Internal memory capable of storing up to 1000 conductivity measurements and calibration records, facilitating data retention and audit trails crucial for biomanufacturing and synthetic biology research.
  • RS232 and USB connectivity interfaces for seamless integration with laboratory information management systems (LIMS) and digital recordkeeping.

Designed for biotechnology and analytical laboratories, the AquaSearcher AB33EC is essential for precise molecular biology workflows, environmental monitoring, and biomedical engineering applications such as live-cell media quality control. Its compact benchtop form factor, combined with robust electrochemical measurement capabilities, make it a reliable instrument widely adopted in bioprocessing and molecular diagnostics environments requiring reproducible conductivity and salinity analysis.

Dimensions: 9 x 5 x 2 inches; Weight: 5 lbs; Power supply: 120V, 60Hz. This instrument supports critical functions in the biopharmaceutical production pipeline and offers stable performance for long-term laboratory utilization.

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.
