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:

The ADWA AD8000 is a professional multi-parameter bench meter that measures five parameters simultaneously: pH, ORP (mV), electrical conductivity (EC), total dissolved solids (TDS), and temperature. As a result, it eliminates the need for multiple dedicated instruments on the laboratory bench. This makes it one of the most cost-effective solutions for any analytical laboratory.

Key Features at a Glance

The AD8000 is built around a high-precision microprocessor for stable, reliable results. In addition, it includes several advanced features that simplify daily laboratory work:

• Autoranging EC and TDS — automatically selects the scale with the highest resolution
• pH calibration at 1, 2, or 3 points using 5 memorized buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01)
• ATC for pH via the external temperature probe; ATC or MTC for EC via the probe’s built-in sensor
• Relative mV function for ORP and electrode performance monitoring
• Calibration timeout alarm to remind users when recalibration is due
• GLP (Good Laboratory Practice) data logging to view and document last calibration data
• HOLD feature to freeze the first stable reading on the LCD

Technical Specifications

The AD8000 covers a wide measurement range across all five parameters. Specifically:

The temperature coefficient is fully user-selectable. Moreover, the instrument can disable temperature compensation entirely to measure actual (non-compensated) conductivity when required.

Who Is the AD8000 For?

The AD8000 is designed for professionals who need accurate multi-parameter measurements in a single workflow. For example, it suits:

• University laboratories — analytical chemistry, environmental science, and biochemistry departments
• Pharmaceutical QC labs — where pH, conductivity, and ORP must be verified in one session
• Industrial water treatment plants — for complete bench-based water chemistry analysis
• Food and beverage production — multi-parameter quality control checks in a single step
• Environmental monitoring labs — processing multiple water quality parameters simultaneously

Furthermore, the AD8000’s single-instrument approach simplifies calibration management. Instead of maintaining three separate instruments, one set of calibration solutions covers all five parameters.

What Is Included in the Box?

The AD8000 is supplied complete and ready to use. Consequently, no additional accessories are required to start measuring immediately:

• AD1131B refillable glass pH electrode with BNC connector (1 m cable)
• AD76309 conductivity probe with built-in temperature sensor (1 m cable)
