About this item

This rugged, waterproof portable meter is designed for a wide range of pH, mV, ORP, 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 two measuring channels allowing users to measure pH and dissolved oxygen simultaneously or view each channel separately.

Up to a five point pH calibration using automatic buffer recognition of NIST or DIN buffer groups
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. Warrenty; 3 years.

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

Delivery: Supplied with four AA batteries, literature CD, printed quick start guide, computer interface cable and meter test certificate.
The kit additionally includes: 8107UWMMD ROSS gel-filled epoxy pH/ATC Triode (3 m cable), 087010MD RDO optical DO probe (3 m cable), pH 4,01/pH 7,00/pH 10,01 buffer pouches, Orion ROSS electrode storage solution, Orion 1413 µS conductivity standard pouches, rinse solution pouches, protective armor with electrode holder and hard carrying case.
