Sper Scientific 850045 Dissolved Oxygen Pen: Accurate Water Quality Measurement in the Palm of Your Hand

The Sper Scientific 850045 Dissolved Oxygen Pen is a portable, user-friendly meter designed for fast and accurate water quality analysis. Its compact and lightweight design makes it easy to carry, while its intuitive one-hand operation simplifies the process of calibration and measurement, making it ideal for both field and lab use. This pen is an essential tool for professionals who require reliable dissolved oxygen readings on the go.

Key Features and Benefits:

• Versatile Applications: This pen is perfect for measuring dissolved oxygen to assess water quality in a wide range of settings, including environmental testing, industrial and municipal wastewater treatment, aquaculture (aquariums and fish hatcheries), and laboratory research.
• Simple One-Hand Operation: Designed for efficiency, the pen allows for easy, single-handed use. It features automatic temperature compensation (ATC), which corrects for temperature fluctuations to ensure accurate DO readings. Calibration is straightforward—simply expose the probe to air.
• Advanced Probe Technology: The polarographic probe includes a built-in temperature sensor and features easy-to-replace, pop-off probe heads, minimizing downtime and simplifying maintenance.
• Dual-Display and Data Functions: The clear LCD screen simultaneously displays dissolved oxygen levels and temperature readings. It also includes a data hold function to freeze readings on the screen and can recall the minimum and maximum values recorded during a measurement session.
• Durable and Waterproof: With an IP67 waterproof rating, this pen is built to withstand harsh environments. It even floats if accidentally dropped in water, ensuring it's never lost during fieldwork.
