pH/mV/°C meter, handheld, Orion Star™ A221

This rugged, waterproof portable meter is ideal for a wide range of applications and advanced pH analysis in the field. It measures pH, mV, relative mV or ORP with temperature and can be used in the most demanding locations thanks to its IP 67-rated housing.

Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
Up to a five point pH calibration; automatic buffer recognition of NIST or DIN buffer groups with choice to manually enter custom buffer values
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

Designed to offer the reliability you need in a user-friendly package for your dedicated pH testing needs. This waterproof, portable meter displays critical data with your measurement including temperature, date and time, read type, measurement stability, active calibration info and power source status.

Relative humidity range 5 to 85%, non-condensing.
