AD630 is a heavy-duty portable waterproof meter for DO (Dissolved Oxygen) and temperature measurements, designed to provide laboratory results and accuracy even under harsh industrial conditions.

Main features include

• DO readings displayed in ppm or % saturation units
• DO calibration at 1 or 2 standard points (0 and 100%), or at 1 custom point (>20%)
• Galvanic DO probe with built-in temperature sensor
• Automatic temperature compensation
• Log-on-demand
• Setup mode for setting altitude & salinity compensation factors, temperature measure unit (°C or °F), serial communication parameters, date & time, auto-off, instrument ID code
• HOLD feature to freeze stable reading on the LCD
• GLP feature to view last calibration data
• PC interface via RS232 port

Galvanic probe: Unlike polarographic probes, Galvanic DO probes do not require any conditioning time when the unit is switched on, saving time when many measurements are required.

Supplied complete with

AD8001/3 galvanic DO probe with built-in temperature sensor, spare membrane with O-ring, electrolyte solution (30 ml bottle), AD9551 serial communication cable, 1.5V AA alkaline battery (4 pcs), user manual.
