HORIBA LAQUA WQ-300 Series: Field-type Multi-digital Water Quality Meter

Introducing the LAQUA WQ-300 Series

Designed for those who seek a deeper understanding, the LAQUA WQ-300 Series offers a new dimension of measurement enjoyment. This new generation of LAQUA meters is packed with diverse functions and possibilities.

LAQUA is HORIBA's brand for water quality analysis. The name LAQUA, meaning 'water' in Latin, embodies our commitment to providing flexible solutions and being a trusted water quality analyzer.

Key Features for Enhanced Field Measurement

The LAQUA WQ-300 Series is engineered to make field measurements more comfortable and efficient through a variety of innovative functions:

User-Friendly Design

Holder & Hook Structure: Sensors attach securely to the meter body, allowing multiple sensors to be grouped together. This design ensures ease of carrying and handling, even with up to 3 channels.
Push-Pull Lock Connector: Features a push-pull lock connector for quick, one-touch sensor detachment and attachment, enabling smooth sensor replacement.
MicroUSB Port: Equipped with a MicroUSB port for PC connectivity and USB power supply. A USB-compatible battery (commercially available) can also be used, allowing measurements without worrying about battery capacity.
Meter Stand: A fold-out stand on the back of the meter allows for easy viewing and operation when placed on a surface.

Robust and Durable Construction

Toughness: Designed with a waterproof, dustproof, and shock-resistant structure (IP67 equivalent). The double-molding technique enhances grip and impact resistance.

Advanced Display

Color Graphic Blanview® LCD: Utilizes a Blanview® display that efficiently collects ambient light, ensuring excellent visibility in both dark conditions and direct sunlight.

Seamless Data Management

Wireless Data Transmission: Switch to wireless data transfer mode to send measurement data to your PC via a web browser, allowing for easy data selection and CSV file viewing.

Digital Sensor Technology

Experience HORIBA's advanced electrode technology integrated with digital sensors, storing all essential information directly within the sensor head.

Maintenance-Free pH Sensor: Features a gel-filled internal liquid (KCl), eliminating the need for refilling internal liquid and simplifying daily measurements. The sensor cartridge is replaceable for cost and environmental efficiency.
Wide Range Conductivity Sensor: The 4-electrode system enables wide-range measurements from 10 µS/cm to 2000 mS/cm. It is designed for small sample volumes and features a simple, easy-to-maintain shape with a replaceable cartridge.
Optical DO Sensor: Utilizes optical phase measurement technology (JIS/ISO compliant) for stable response, less affected by flow rate. It offers automatic salinity and barometric pressure compensation.
Sensor Information Storage: Each digital sensor head contains a built-in circuit that stores sensor ID (model/serial number), calibration data, and settings, ensuring accurate and traceable measurements.
Versatile Connectivity: Dedicated sensor heads and connectors (sold separately) allow traditional Ion and ORP electrodes to be connected, expanding measurement capabilities.
Customizable Measurement: Configure your system with up to 55 different sensor combinations to suit specific application needs.
Sensor Status Indication: LED indicators on the sensor and status marks on the meter visually confirm stable measurement conditions.

Comprehensive Carrying Case

The dedicated carrying case provides organized storage for the meter, various sensors, calibration solutions, and accessories, ensuring everything needed for field measurements is kept safe and accessible.
