This durable and highly accurate pen meter is purpose-built for measuring both dissolved oxygen (DO) and temperature in a wide range of environments. Designed for portability and ease of use, it is ideal for field testing in aquatic research, environmental monitoring, aquaculture, or educational laboratory experiments. The unit's streamlined design and intuitive interface allow users to take fast, reliable readings with minimal setup. Its waterproof housing ensures durability even in challenging conditions, and the ability to float on water provides peace of mind during outdoor use.Educational Applications: Support biology and chemistry lessons by measuring dissolved oxygen levels in various water samples. Demonstrate environmental science concepts such as oxygen saturation in freshwater versus saltwater. Use in field trips to ponds, lakes or rivers to compare ecological conditions in different aquatic habitats. Conduct long-term investigations into how temperature affects oxygen levels in water. Reinforce scientific literacy and data collection skills with real-time readings and analysis. Key Features: Microprocessor-controlled for precise and rapid DO and temperature measurements. Large LCD display shows both DO and temperature simultaneously for at-a-glance readings. One-button calibration with automatic temperature compensation (ATC), manual salinity (MSC), and altitude compensation (MAC). Waterproof housing rated IP57 - floats if dropped in water. Data-hold, Max/Min memory, calibration percentage display (PTS), and switchable °C/ °F or ° units. Low battery warning and energy-efficient operation. Easy maintenance with replaceable DO probe module. Suitable for laboratory or field use across educational institutions.
