About this item
Accurately measure pH, conductivity, and temperature with the Orion™ Star™ A325 pH/Conductivity Portable Meter for high performance in challenging field tests.
- Combined convenience with the benefits of a pH meter and conductivity meter in one easy-to-use system
- Measure pH, mV, relative mV, or ORP with temperature on channel one and measure conductivity, TDS, salinity, or resistivity with temperature on channel two
- 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
- Capture critical readings with measurement stability indicator and selectable read modes
- Auto-Read mode holds a stable reading, Continuous mode shows changing readings with hold option, and Timed mode logs data at specific intervals
- Three-year meter warranty
Get high accuracy and premium performance everywhere needed with the Orion™ Star™ A325 pH/Conductivity Portable Meter, designed for a wide range of pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature testing and field applications.
Take measurements at the source with this premium line of portable meters. The Orion™ Star™ A325 pH/Conductivity Portable Meter offers an information-rich screen and user-friendly operation. This rugged, waterproof portable meter is ready to tackle the elements. These meters are designed to be easy to use, dependable field meters that offer advanced features and functions, including a 5000 point date log with sample ID and user ID options, calibration and high/low limit alarms, and password-protected measurement methods. Easily view individual measurements on a full screen display and quickly toggle to a split screen display to view multiple measurements simultaneously. 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. Use linear, non-linear, EP (USP), or off conductivity temperature compensation with 5, 10, 15, 20, or 25 °C reference temperatures. Flexible power options with AA batteries or optional universal power adapter. Non-volatile meter memory ensures data and settings are protected, even with loss of power.
Evaluate samples in the most demanding locations using this waterproof meter with IP67-rated housing. Use the two channels to measure pH and conductivity simultaneously or view each channel separately. Log up to 5000 data point sets with time/date stamp and transfer logs to a printer or computer.
