Lovibond pH1 – High-Accuracy Pocket pH/Temperature Meter
The Lovibond pH1 is a robust, waterproof, and portable instrument designed for precise and reliable measurement of pH and temperature in various environments. This handheld device utilizes a unique flat electrode which contributes to its robust nature, making it highly suitable for demanding field conditions. The meter displays both pH and temperature simultaneously, along with an indicator for remaining battery life.
The DTK range of pocket waterproof testers, including the pH1, is designed to float in water, providing flexibility for monitoring water conditions even in rugged situations.
Key Features
• Dual Parameter Measurement: Reads both pH and Temperature simultaneously.
• Rugged and Waterproof: Designed to meet the IP-57 standard for water resistance, ensuring durability and reliability in the field.
• Unique Flat Electrode: Features a very robust flat electrode design.
• Automatic Temperature Compensation (ATC): Ensures accurate pH readings across the entire specified temperature range (0 to 90 °C).
• Portability: Lightweight at only 85 grams and comes in a portable design.
• Energy Saving: Includes an auto shut-off feature after 10 minutes of non-use.
• Data Management: Features include Display Maximum/Minimum Value and Data hold functionality.
• Redox Capability: The pH1 can also be used with the optional RE1P probe to measure Redox (mV) from -1000 to 1000 mV.
Applications
The Lovibond pH1 is a versatile tester suitable for a wide range of water analysis needs, including:
• Swimming Pools, Aquaria, and Fish Hatcheries
• Laboratory Use and Quality Control
• Drinking Water Treatment and Water Conditioning
• Industrial Water, Freshwater, Saltwater, and Groundwater
• Boiler Water and Cooling Water
• Food and Beverage Processing
• Education
Calibration
The meter supports both two and three-point calibration procedures. Standard calibration buffers used include pH 4.00, pH 7.00, and pH 10.01. The calibration procedure typically begins with the pH 7 buffer. After calibrating to pH 4 or pH 10, the display indicates a percentage value that reflects the condition of the electrode based on the calibration slope, with 100% being the ideal slope.
