Orion Star™ A323 Dissolved Oxygen Meter, Handheld

: Thermo Orion

This portable DO/RDO meter is designed for a wide range of dissolved oxygen and temperature testing and field applications. It can be used with a RDO optical or a polarographic DO probe. The meter is suitable for use in the most demanding locations thanks to its IP67-rated housing.

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
Non volatile meter memory ensures your data and settings are protected, even with loss of power
Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections
Flexible power options with AA batteries or optional universal power adapter

Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (winkler titration) and zero point options. Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings. Three year meter warranty.

: TUV 3-in-1 and FCC class A.

: Supplied with four AA batteries, literature CD, printed quick start guide, computer interface cable and meter test certificate.
The kit additionally includes: 087010MD RDO optical DO sensor with 3 m cable, calibration sleeve and guard, Orion Star A series portable meter armor and Orion Star A series hard-sided field case.
