Multi-parameter meter (pH/mV/DO), bench, Orion Star™ A216

This benchtop meter is ideal for a wide range of applications and advanced pH and dissolved oxygen analysis in the lab. It offers two measuring channels allowing users to measure pH and dissolved oxygen simultaneously or view each channel separately. Can be used with RDO optical or polarographic DO probes.

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 2000 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 universal power adapter or optional AA batteries
Three year meter warranty

IP54-rated housing resists dust and splashes and can be wall-mounted if table space is limited.

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.

Perform up to a five point pH calibration using automatic buffer recognition of NIST or DIN buffer groups with choice to manually enter custom buffer values and calibration editing option that allows individual points to be fixed without a full recalibration. 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.

: Supplied with electrode stand, universal power adapter, literature CD, printed quick start guide, computer interface cable and meter test certificate.
The kit additionally includes: 8157BNUMD ROSS Ultra Triode refillable epoxy-body pH/ATC electrode, 083005MD Polarographic DO sensor with calibration sleeve, ROSS pH buffer and storage solution kit, DO sensor maintenance kit and BOD adapter, funnel and stirrer.
