About this item

This portable DO/RDO meter is ideal for a wide range of applications and advanced dissolved oxygen analysis in the field. It can be used with RDO optical or a polarographic DO probes. 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 and Continuous shows changing readings with hold option
Data log collects and date/time stamps up to 1000 measurement sets
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.

Certifications: CE, TUV 3-in-1 and FCC Class A

Delivery: Supplied with four AA batteries, literature CD, printed quick start guide, computer interface cable, meter test certificate and 3-year replacement warranty.
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.
