As we observe World Environment Day 2026 on June 5, the global focus shifts toward innovative technologies essential for monitoring and safeguarding our natural resources. Addressing increasingly complex environmental challenges requires precision instruments that can provide reliable data in both the laboratory and the field.  

OHAUS supports these environmental protection efforts by delivering a broad range of products designed to handle various testing parameters with high technical accuracy.  

The Rise of Multi-Parameter Testing 

In the environmental sector, the demand for multi-parameter instruments has grown significantly. Utilizing a single meter to perform multiple measurements simultaneously offers several advantages:  

• Cost Efficiency: Reduces the need for multiple specialized devices.  

• Operational Streamlining: Simplifies workflows for end users.  

• Comprehensive Data: OHAUS provides integrated units capable of measuring pH, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature.  

Precision in the Lab: AQUASEARCHER™

The AQUASEARCHER™ Multi-Parameter Analyzer AB33M1 is engineered for high-performance laboratory applications. This benchtop meter prioritizes user experience and data integrity through several key features:  

• Intelligent i-Steward System: This system ensures consistent measurement accuracy by continuously monitoring the status of the electrode.  

• User-Friendly Interface: Equipped with a 6.5-inch LCD and a touch keypad, the device simplifies calibration, setup, and parameter switching.  

• Advanced Data Management: With internal storage for 1000 entries and versatile connectivity via RS232 and USB, it facilitates seamless data transfer for academic and industrial research.  

Durability in the Field: Starter™ Multi-Parameter Analyzer ST400M 

For environmental monitoring in rugged or wet conditions, the STARTER™ 400M Portable Water Analysis Meters provide a robust alternative. These handheld devices are built to withstand the rigors of field work:  

• Ruggedized Design: Featuring waterproof housing, these meters are specifically designed for prolonged use in challenging environments.  

• Extended Battery Life: Powered by a rechargeable lithium battery, the ST400M supports up to 40 hours of continuous testing and is rated for over 300 charge cycles to minimize field downtime.  

• Secure Data Logging: Even in remote locations, users can store up to 1000 records and later transfer them to a laptop via a micro-USB port, ensuring critical environmental data is never lost.  

Commitment to a Greener Future 

OHAUS remains dedicated to empowering environmental professionals with the tools needed to monitor water quality and soil health effectively. By providing high-quality electrochemistry products, OHAUS helps ensure that environmental protection efforts are backed by precise, verifiable data.
