Why Choose the AQUASEARCHER AB33EC Benchtop Conductivity Meter? Solving Complexity, Inconsistency & Workflow Challenges

Achieve confident, repeatable results with intelligent features that directly address common laboratory pain points.

• Simplify Operation with an Intuitive, Smartphone-Style Interface: Complex menu structures slow down work and increase the risk of errors. The AB33EC conductivity meter features a 6.5-inch segment and dot matrix LCD with a capacitive touch keypad. Changing parameters, executing setup, and performing calibration is as simple as using a smartphone, reducing training time and making operation effortless for all lab staff.

• Ensure Measurement Consistency with Intelligent i-Steward Technology: Forgetting to calibrate can lead to unreliable data. The built-in i-Steward feature includes a calibration due alarm that proactively reminds you when calibration is required. This ensures your precision conductivity meter always delivers repeatable and consistent measurement accuracy, providing optimal peace of mind for critical quality control tasks.

• Capture and Manage Data with Ease: Manual data transcription is prone to errors. The AB33EC features a 1,000 measurement memory, allowing you to store results directly on the instrument. With built-in RS232 and USB Device connectivity, transferring data to a PC or printer for analysis, reporting, and traceability is seamless and efficient.

• Achieve Versatile, High-Accuracy Measurements Across a Wide Range: From ultrapure water to high-concentration industrial samples, this benchtop meter covers it all. It measures conductivity (0.001 µS/cm to 1000 mS/cm) , TDS, salinity, and resistivity (1 Ohm to 100 MOhm) with an impressive accuracy of ±0.5% of reading. The included STCON7 conductivity electrode ensures you're ready to measure right out of the box.
