Multi-parameter meter (pH/mV/conductivity), bench, Orion Star™ A215

About this item

This benchtop meter is ideal for a wide range of applications and advanced pH and conductivity analysis in the lab. It offers two measuring channels allowing users to measure pH and conductivity simultaneously or view each channel separately.

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

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 conductivity, TDS, salinity or resistivity with temperature 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. Perform up to a five point conductivity calibration. Calibration editing option allows individual points to be fixed without a full recalibration. 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.

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

Delivery: Supplied with electrode stand, universal power adapter, literature CD, printed quick start guide, computer interface cable, meter test certificate and 3-year replacement warranty.
The kit additionally includes: 8157BNUMD ROSS Ultra Triode refillable epoxy-body pH/ATC electrode, 013005MD DuraProbe 4-cell (K=0,475) epoxy-body conductivity sensor, ROSS pH buffer and storage solution kit and Orion 1413 µS conductivity standard (5× 60 ml).
