Don’t leave your measurements to chance when analyzing samples outside the lab. Orion Star A222 conductivity portable meters are designed to offer the reliability you need in a user-friendly package for your dedicated conductivity 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.
  • Measure conductivity, TDS, salinity or resistivity with temperature
  • Perform up to a five point conductivity calibration
  • Auto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrate
  • Use linear, non-linear or off conductivity temperature compensation with 15°C, 20°C or 25°C reference temperatures
  • Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
  • Capture your critical readings with 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 universal power adapter
  • IP67-rated housing is waterproof for rugged field operation
  • Meter kits include hard-sided field case and protective meter armor with electrode holders, adjustable wrist/belt strap and built-in meter stand
