ADWA AD330 is a professional waterproof portable meter for electrical conductivity (EC), total dissolved solids (TDS), and temperature. Unlike standard portable meters, it is purpose-built for demanding field professionals who need GLP-compliant, traceable results anywhere — not just in the laboratory. As a result, it is the preferred choice for environmental monitoring teams, water treatment field technicians, and industrial compliance engineers across Egypt.

Key Features at a Glance

The AD330 combines waterproof durability with advanced measurement capabilities. In particular, it offers:

• Full waterproof construction — genuine field and rainproof protection for real outdoor conditions
• 5 autoranging EC ranges (0.00 µS/cm to 199.9 mS/cm) — maximum resolution at every measurement level
• 5 autoranging TDS ranges — automatically selects the most precise scale
• ATC and MTC — automatic or manual temperature compensation, user-selectable
• User-selectable temperature coefficient — adaptable to different solution types
• Stability indicator — signals when the reading has stabilised and is ready to record
• GLP capability — logs calibration data for fully documented, traceable field records
• User-selectable instrument ID code — essential for multi-instrument field teams managing multiple meters simultaneously

Technical Specifications

The AD330 covers the full practical range of EC and TDS measurement in a single autoranging instrument. Specifically:

Parameter	Range	Detail
EC	0.00 µS/cm – 199.9 mS/cm	5 autoranging ranges
TDS	Full range	5 autoranging ranges
Temperature	ATC / MTC	User-selectable coefficient
Construction	Waterproof	Field and rainproof rated
GLP		Calibration history logging
Instrument ID		User-selectable code

The stability indicator eliminates guesswork in the field. Therefore, operators know precisely when a reading is settled and ready to record — preventing premature data capture that leads to inaccurate results.

Who Is the AD330 For?

The AD330 is designed for professionals who work in outdoor, wet, or chemically challenging environments. For example, it is widely used for:

• Environmental field monitoring — rivers, canals, drainage water, and irrigation channels across Egypt
• Water treatment plant surveys — field technician measurements during plant performance assessments
• Industrial effluent compliance — on-site EC/TDS monitoring for water discharge permit requirements
• RO and NF system checks — field performance verification at remote or unmanned installations
• Agricultural irrigation management — large-scale farm water quality monitoring and salinity control

Furthermore, the GLP feature makes the AD330 essential for ISO 17025 field work and audit-ready environmental monitoring programs — where every reading must be traceable to a documented calibration record.

Complete Field Water Quality Kit

The AD330 pairs directly with two other ADWA waterproof portable meters to create a complete 5-parameter field water quality kit:

• ADWA AD130 — pH and ORP measurement (splash-proof, -20 to +120°C)
• ADWA AD330 — EC, TDS and temperature (this instrument)
• ADWA AD630 — dissolved oxygen and temperature (galvanic probe, instant readings)

Together, these three instruments cover pH, ORP, EC, TDS, DO, and temperature — everything needed for comprehensive water quality assessment in a single field visit. Bundle pricing is available from Eagle Systems.

What Is Included in the Box?

The AD330 ships complete and field-ready. Consequently, no additional accessories are needed before first use:

• AD76309 conductivity/TDS probe with built-in temperature sensor (1 m cable)
• EC calibration solution sachet
• Alkaline batteries
• User manual
