Description

Thermo Scientific Orion Star A122 Conductivity Portable Meters combine simplicity with accuracy. A large LCD displays conductivity or TDS readings along with temperature. Icons provide quick updates on battery life and completed calibration status. Simple button layout and onscreen messages help with calibration and setup menu choices.

• Large, informative screen clearly shows the main information, including conductivity or TDS reading, temperature in ºC or ºF, meter mode and battery life
• Don’t miss a reading – AUTOREAD ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable
• Selectable cell constant
• Manual calibration or automatic calibration when using a Thermo Scientific Orion conductivity standard (sold separately)
• Selectable reading reference temperatures of 20 °C or 25 °C for an accurate result
• Non-volatile memory holds up to 50 data points
• Four AA batteries (included) provide over 2000 hours of operation or purchase the universal power adapter (sold separately) to run meter on AC power
• Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing
• 3 year meter manufacturer’s replacement warranty
