The ADWA AD630 is a professional waterproof portable meter for dissolved oxygen (DO) and temperature measurement. What sets it apart from other portable DO meters is its galvanic probe — a significant technical advantage over the more common polarographic probe instruments. As a result, it delivers immediate, accurate readings the moment the probe is immersed, with no warm-up or conditioning time required.

Galvanic vs. Polarographic — Why It Matters

Most portable DO meters use polarographic probes that require a conditioning period after power-on before they give accurate readings. The AD630, however, uses a galvanic probe that generates its own electrochemical signal without any applied voltage. Therefore, it is ready to measure instantly — a critical advantage in aquaculture emergencies and multi-site field surveys where every minute counts.

	Galvanic (AD630)	Polarographic
Warm-up time	None — instant readings	5–30 minutes
Applied voltage	Not required	Required
Field mobility	Move freely between sites	Wait at each site
Emergency response	Immediate	Delayed

Key Features at a Glance

In addition to the galvanic probe advantage, the AD630 includes a comprehensive set of professional features:

• DO readings in ppm (mg/L) and % saturation — switchable units for different reporting standards
• DO calibration at 1 or 2 standard points (0% and 100%) or a custom point (>20%)
• Automatic temperature compensation (ATC) for accurate DO readings across all water temperatures
• Altitude compensation — essential for accurate readings at elevated sites above sea level
• Salinity compensation — corrects for dissolved salt content in marine and brackish water
• Log-on-demand data recording for field data capture
• GLP feature — calibration history logging for traceable, documented records
• RS232 PC interface — direct data transfer to computer via AD9551 cable
• HOLD feature, auto-off, instrument ID code, and °C/°F selection

Technical Specifications

The AD630 covers the full dissolved oxygen range required for both environmental monitoring and aquaculture management. Specifically:

Who Is the AD630 For?

The AD630 is designed for professionals who need fast, reliable DO measurements in challenging field conditions. For example, it is the instrument of choice for:

• Aquaculture and fish farms — continuous DO monitoring at Red Sea coastal farms, Nile Delta fish farms, and Mediterranean aquaculture sites across Egypt
• Environmental monitoring — rivers, lakes, canals, and wetlands where DO is a key indicator of ecosystem health
• Wastewater treatment plants — aeration basin control in biological treatment processes
• BOD testing — dissolved oxygen measurement for Biological Oxygen Demand sample preparation
• University fieldwork — limnology, hydrology, and environmental science practical courses

Furthermore, the altitude and salinity compensation features make the AD630 accurate across Egypt’s diverse geography — from coastal marine farms at sea level to agricultural and industrial sites further inland.

What Is Included in the Box?

The AD630 ships complete with all consumables needed for immediate field deployment. Consequently, teams can begin measuring on the same day as delivery:
