Ohaus Aquasearcher AB33M1-F Benchtop Multi-Parameter with ST310 pH Electrode & STCON3 Probe
The Ohaus Aquasearcher AB33M1 Benchtop Multi-Parameter represents the next evolution in OHAUS' acclaimed Starter Series, delivering an easy-to-use and accurate multi-parameter measurement solution designed with reliable performance and intuitive user interface at its core. Capable of measuring up to seven critical water quality parameters—pH, oxidation-reduction potential (ORP), conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature—the AB33M1 utilizes two independent measuring channels that can operate simultaneously, enabling efficient multi-parameter analysis and significantly reducing testing time in busy laboratory environments. The intelligent i-Steward system ensures repeatable and consistent measurement accuracy through real-time electrode condition monitoring, "Electrode Dirty/Broken" alerts, and calibration due reminders, providing optimal peace of mind and maintaining measurement integrity across all seven parameters. With on-screen text prompts, menu-specific function keys, and a multi-language interface displayed on the large 6.5-inch segment and dot matrix LCD with backlight, the AB33M1 makes changing parameters, executing setup, and performing calibration as simple and intuitive as using a smartphone.
Engineered for versatility in standard laboratory applications, the AB33M1 features multifunctional capacitive touch keypads with three context-sensitive keys that change based on current operation, ensuring buttons are never clogged with sample residue while enabling most operations to be completed within three simple steps. Advanced measurement capabilities include auto-endpoint mode (Auto-Stop holds stable readings, Continuous displays changing readings) and up to 3-point pH calibration using automatic buffer recognition across three predefined buffer groups for simplified calibration procedures. Conductivity measurement flexibility is provided through selectable cell constants compatible with both 2-cell and 4-cell conductivity probes, enabling measurements from ultrapure water to sewage applications, while adjustable TDS factor and automatic temperature compensation with linear coefficient adjustment ensure accurate results across diverse sample types. Selectable reference temperatures of 20°C or 25°C for temperature-compensated conductivity readings, combined with a 1,000-item measurement and calibration memory with date/time stamps for traceability, support comprehensive data documentation requirements. Standard RS232 and USB interfaces (included) enable connection to external devices such as printers and computers for expanded data transfer and storage capabilities. Constructed with durable ABS housing, adjustable standalone electrode holder for flexible electrode positioning, and operating on AC adapter (included), the Aquasearcher AB33M1 delivers reliable, efficient, and user-friendly multi-parameter water quality analysis for educational laboratories, environmental testing, aquaculture operations, and quality control applications requiring accurate, traceable measurements across multiple water quality parameters.

Key Differences Between AB33EC, AB33PH, and AB33M1 Benchtop Meters
1. Measurement Parameters:
- AB33PH: Measures pH, oxidation-reduction potential (ORP), and temperature - designed specifically for acidity/alkalinity and redox potential measurements using pH electrodes.
- AB33EC: Measures conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature - designed for ionic content and dissolved solids measurements using conductivity probes.
- AB33M1: Measures all seven parameters (pH, ORP, conductivity, TDS, salinity, resistivity, and temperature) - a comprehensive multi-parameter system with two independent measuring channels that can work simultaneously.
2. Channel Capability and Versatility:
- AB33PH and AB33EC: Single-channel instruments dedicated to one measurement type (pH/ORP or conductivity-based parameters) - ideal for laboratories focused on specific testing requirements.
- AB33M1: Dual-channel instrument allowing simultaneous measurement of different parameters (e.g., pH and conductivity at the same time) - ideal for laboratories requiring comprehensive water quality analysis and maximum efficiency with one meter replacing multiple instruments.
In Summary: Choose the AB33PH for pH/ORP-only applications, the AB33EC for conductivity/TDS/salinity-only applications, or the AB33M1 for comprehensive multi-parameter water quality analysis with the advantage of two independent channels operating simultaneously. All three meters share the same user-friendly 6.5-inch touchscreen display, i-Steward monitoring system, three-step operation, 1,000-item memory, and dual RS232/USB connectivity.
