Description
The Thermo Scientific Orion Star A111 is a benchtop pH meter designed for routine measurements of pH, mV, and temperature in laboratory environments. It combines ease of use with dependable performance, making it ideal for laboratories requiring accurate, day-to-day pH analysis.
Key Features:
- Large LCD Display: Clearly shows pH or mV readings, temperature, meter mode, calibration data, and power status.
- Auto-Read Function: Automatically locks in a stable reading and indicates when stability is reached for precise results.
- Three-Point Calibration: Supports up to three-point calibration with automatic buffer recognition (USA/NIST and DIN standards).
- Data Storage: Non-volatile memory stores up to 50 data points for quick access and recall.
- Flexible Power Options: Can operate using a universal AC adapter or four AA batteries for added mobility.
- Durable Design: IP54-rated housing for splash resistance; wall-mountable for space-saving installation.
