Overview
With over 60 years of engineering excellence, HORIBA offers a diverse range of water quality analyzers and electrodes suitable for everyday laboratory needs and demanding applications. The LAQUA 200 Series provides advanced handheld solutions for accurate water quality measurement, covering parameters such as pH, ORP, Conductivity, Total Dissolved Solids (TDS), Resistivity, Salinity, and Dissolved Oxygen (DO).
Detailed Features
- Impact Resistant, Eco-friendly, Shock & Scratch Resistant, & Non-slip: Constructed with durable polycarbonate and TPE materials, offering long-lasting, recyclable, and abrasion-resistant properties with a non-slip grip.
- Backlit, Large LCD Screen: Features a scratch-resistant monochrome digital LCD (50 x 50 mm) with white LED backlight for clear visibility in any lighting condition.
- Hands-free Testing: Optional wrist strap or lanyard allows for hands-free operation, or the meter can be placed in its carrying case.
- Built-in Electrode Holder: Two grooves on the meter securely hold electrodes, allowing them to be easily placed in solutions.
- Ergonomic Design: Lightweight housing made of polycarbonate with a TPE material covering provides a comfortable, non-slip grip for field use.
- High Battery Capacity: Utilizes AA batteries for increased power capacity and extended battery life (up to 2.5x compared to AAA).
- 9-Button Keypad Minimal Matrix: Simplified operation with a reduced number of buttons.
- Integrated Foldable Meter Stand: A collapsible stand is built into the back of the meter for convenient placement and storage.
- IP67 Waterproof and Dustproof: Fully protected against dust ingress and capable of withstanding water immersion up to 1 meter for 30 minutes.
- PC / Printer Communications: 220 models support GLP compliance, allowing data transfer to a computer via USB or printing via RS232 cable (cables sold separately).
Display and Measurement Modes
The LAQUA 200 Series offers an easy-to-read display that shows electrode condition, reading stability, parameter, and temperature simultaneously.
Electrode Status Indicator
An electrode icon on the display indicates the condition of the electrode after calibration, categorized as Excellent, Very Good, or Fair.
Temperature Sensor Indicator
When a temperature sensor is connected, 'ATC' (Automatic Temperature Compensation) is displayed. If disconnected, 'MTC' (Manual Temperature Compensation) is shown.
Measurement Modes
- Auto Stable (AS): Displays live readings until stability is reached, indicated by a blinking annunciator.
- Auto Hold (AH): Locks the stable reading, indicated by a blinking annunciator followed by a 'HOLD' light.
- Real Time: Displays live readings continuously without stability indicators.
Diagnostic Messages
The meters provide self-diagnostic messages to help identify and troubleshoot measurement or meter issues quickly.
Rugged Carrying Case
A durable carrying case is included to securely store and protect the meter, electrodes, solutions, and accessories during field use or for storage. Connectors can remain attached to the meter when stored.
