Pocket Dissolved oxygen tester 25-PDO100

Lab Expo Pocket Dissolved Oxygen Tester is a compact, high-performance device designed for accurate measurement of dissolved oxygen (DO) levels across various liquid samples, including water, wastewater, and other solutions. Equipped with a polarographic sensor, this portable DO tester provides reliable and precise results, making it an essential tool for environmental monitoring, water treatment, and research applications.

This DO tester offers a dissolved oxygen range from 0.0 to 20.0 mg/L (ppm) with an accuracy of ±0.5 mg/L, allowing users to assess oxygen concentration accurately. The device also measures the percentage saturation of oxygen, with a range from 0.0 to 200.0% and an accuracy of ±10% F.S. The system includes automatic temperature compensation across a range of 0°C to 40°C (32°F to 104°F), ensuring reliable measurements regardless of environmental fluctuations.

For enhanced functionality, the system menu provides control over six adjustable parameters, including the number of calibration points and temperature units. Users can perform 1- or 2-point calibration using air-saturated water and zero oxygen solution for accurate baseline measurements. The device also supports manual salinity correction (0–35 g/L) and barometric pressure adjustment (60.0–112.5 kPa or 450–850 mmHg), allowing the tester to compensate for environmental variables that may impact DO readings.

Designed with user convenience in mind, the Lab Expo Pocket Dissolved Oxygen Tester features both manual and automatic data hold functions to freeze final readings for easier viewing and recording. It also has a manual or automatic power-off feature that activates eight minutes after the last key press, conserving battery life. The tester is powered by a long-lasting battery with approximately 150 hours of operational time. An intuitive battery indicator keeps users informed of the remaining battery capacity, ensuring continuous operation in field conditions.

The tester's waterproof design adds durability, protecting it from harsh environmental conditions, while a reset function allows users to restore settings to default when needed. With dimensions of 175 × 40 mm and weighing just 100 grams, this DO tester is highly portable and easy to carry on field assignments. The 6-pin mini plug connector adds further convenience for attachment with compatible accessories.
