Thermo Scientific™ Orion Star™ A112 Benchtop Conductivity Meter
Take simple conductivity, TDS and temperature measurements with this benchtop conductivity meter with easy operation for basic lab testing.
Brand: Thermo Scientific™ STARA1120
Description
Take simple, routine conductivity, total dissolved solids (TDS) and temperature measurements with the Thermo Scientific™ Orion Star™ A112 Benchtop Conductivity Meter. This instrument, intended for basic conductivity analysis in the lab, is easy-to-use and budget-friendly. Obtain temperature compensated readings using linear option with 20°C or 25°C reference temperatures. Quickly navigate setup menus and ensure consistent calibrations using the simple keypad layout and on-screen text prompts. Use the included electrode stand to easily place sensors in samples and simplify storage.
The A112 Benchtop Conductivity Meter features a selectable cell constant, as well as selectable reading reference temperatures of 20°C or 25°C to ensure accurate results.
- Large, informative LCD screen clearly shows the main information including conductivity or TDS reading, temperature, meter mode and power source.
- Thermo Scientific™ AUTO-READ™ ensures you don't miss a reading. It locks in the stable reading on your screen and a ready indicator alerts when readings are stable.
- Included electrode arm and newly designed holder make it easier to maintain and place probes into samples.
- Meter plugs 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.
- Nonvolatile memory holds up to 50 data points.
- IP54-rated housing withstands splashes.
- Meter mounts to wall, saving bench space.
Warranty:
- Three-year meter replacement
