Thermo Scientific Orion Star A112
Conductivity Benchtop 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 power source
- 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
- Selectable reading reference
temperatures of 20 °C or 25 °C
for an accurate result
- Included electrode arm and
newly-designed holder make
it easier to maintain and place
probes into samples
- Plug the meter into almost any
power outlet with the included
universal power adapter, or use
four AA batteries (sold separately)
to run the meter on DC power
- Non-volatile memory holds up to
50 data points
- The IP54-rated housing can handle
splashes and can be wall-mounted
if table space is a problem
- 3 year meter replacement warranty
