Conductivity meter, handheld, Orion Star™ A222

Supplier: Thermo Scientific
Orion Star™
This portable conductivity meter is ideal for a wide range of applications and advanced conductivity analysis in the field. The meter is suitable for use in the most demanding locations thanks to its IP67-rated housing.

  • 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 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

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, 20 or 25 °C reference temperatures.

Delivery information: Supplied with four AA batteries, literature CD, printed quick start guide, computer interface cable and meter test certificate.
The kit additionally includes: 013010MD DuraProbe 4-cell (K=0,475) epoxy-body conductivity sensor (3 m cable), Orion 1413 µS conductivity standard pouches (10 pack), Orion rinse solution pouches (10 pack), Orion Star A series portable meter armor, Orion Star A series hard-sided field case.
