WTW Oxi 3310 Portable Dissolved Oxygen Meter
The WTW Oxi 3310 is a rugged, high-performance portable dissolved oxygen analyzer designed for demanding field and laboratory applications. Built with intuitive operation, robust waterproof construction, and advanced data management, it delivers reliable DO, temperature, and saturation measurements across a wide range of environments—from wastewater treatment to aquaculture and pharmaceutical processing.
Key Features
Multi‑parameter measurement – Dissolved oxygen (concentration), oxygen saturation, and temperature with a resolution down to 0.01 mg/L.
Wide measuring range – DO concentration from 0.00 to 19.99 mg/L (and up to 90 mg/L in extended range) with ±0.5% of reading accuracy; saturation from 0.0–199.9% (up to 600%) and partial pressure up to 1250 hPa.
Large data capacity – Manual storage of 200 datasets and automatic interval logging of up to 5,000 records (adjustable interval from 1 second to 60 minutes). Each record includes measured value, temperature, date, time, ID, and calibration status.
Intuitive operation – Clear text menus with tactile‑feedback keys for error‑free handling; a backlit 7‑segment LCD for easy reading in low light.
Extreme durability – IP66/IP67 rated housing, fully waterproof silicone keypad, and a robust outer casing – ideal for outdoor use in any weather.
Built‑in calibration timer – Ensures consistent, reliable results by reminding users when recalibration is due.
Automatic temperature compensation (ATC) – Guarantees accurate readings even with fluctuating sample temperatures.
CMC (Continuous Measurement Control) – Real‑time indicator that shows whether the measured value is within the calibrated range; alerts the user if it deviates.
Saturated air calibration method – Low maintenance requirement with simple, reproducible calibration using the OxiCal® sleeve.
Electrode status display – Shows the condition of the probe immediately after calibration.
Long battery life – Up to 1000 hours continuous operation (150 hours with backlight constantly on); powered by 4×1.5V alkaline or 4×1.2V rechargeable batteries.
Waterproof USB interface – Enables fast, reliable data transfer to a PC or PDA, even under harsh field conditions.
Complete kit supplied – Includes Oxi 3310 meter, carrying case, cleaning solution, electrolyte, replacement membrane caps, polishing paper, stand, beaker, operating manual, CD‑ROM, and batteries.
