This Thermo Electron Orion 420A+ Basic pH/mV/ORP Benchtop Meter Calibrated 8/2011 is in real nice condition and has been tested and seems functions 100%. It came from a lab that was upgrading equipment. We can accept pay- pal or your credit card. Please email me with any questions.
The Orion 420A is a benchtop meter that gives you the basics for fast, accurate pH measurement. This system is ideal for a busy, multi-user laboratory or plant environment. Calibration is fast, easy and accurate with autocalibration using built-in Auto-Buffer-Recognition, built-in buffer/temperature tables, and automatically calculated and displayed electrode slope value. The mV mode makes ORP measurements fast and reliable.
The Model 420A is equipped with RS232 communications that allow the user to record data using the optional Orion Model 900A Printer or a computer.
Features:
- Autocalibration with Choice of 3 Buffers
- ROSS Resolution(tm) to 0.001 pH Units
- Simultaneous pH and Temperature Display
