Orion Star™ A329 Multi-Parameter Meter (pH/ISE/Conductivity/DO), Handheld

This rugged, waterproof portable meter is designed for a wide range of pH, ion concentration, conductivity, dissolved oxygen and temperature testing and field applications. It can be used in the most demanding locations thanks to its IP67-rated housing. The meter offers three measuring channels allowing users to measure pH, conductivity and DO simultaneously or view each channel separately.

Up to five point pH calibrations with calibration editing option that allows individual points to be fixed without a full recalibration
Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings
Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
Measurement stability indicator and selectable read modes – Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals
Data log collects and date/time stamps up to 5000 measurement sets with optional sample ID and user ID
Calibration log stores ten most recent calibrations
Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections

Measure pH, mV, relative mV or ORP with temperature on channel one and measure dissolved oxygen in percent saturation or mg/L with temperature using RDO optical DO probes or polarographic DO probes on channel two.

Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings. Transfer single, range or all data points to printer or computer.

Auto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrate. Use linear, non linear, EP (USP) or off conductivity temperature compensation with 5, 10, 15, 20 or 25 °C reference temperatures. 3-years replacement warranty.
