Thermo Fisher Scientific Inc. unveiled the new Thermo Scientific Orion Star LogR Meters. The exclusive LogR technology uses the resistance across the bulb to provide a new method for electrode analysis and determine sample temperature. The resistance information can be used to detect errors in the electrode, saving analysis time and offering quick troubleshooting of electrode issues. Additionally, these meters allow for temperature-compensated pH readings without the use of a separate temperature input.
Benefits of the Thermo Scientific Orion Star LogR meters include:
o Exclusive LogR technology
- Advanced electrode diagnostic information
- Temperature-compensated pH readings without a separate temperature input
o Orion Star meter benefits:
- Data storage for up to 1000 points with time and date stamp
- Up to five point calibration for pH and ISE, where applicable
- Calibration alarms, average slope and slope of segment
- Storage for up to 10 individually password-protected methods
- Direct control for a Star stirrer probe (sold separately)
- RS232 port for data downloads and meter software updates
- 3-year meter replacement warranty
The Orion Star LogR meter is available in two versions – one with pH input and one with pH and ion-selective electrode inputs. Both meters provide mV readout options, temperature and resistance values when the LogR technology is in use. The meter is available individually, with an electrode or in a complete kit with calibration solutions.
This meter will replace the current Thermo Scientific Orion PerpHecT® LogR(TM) meters – the 320, 350 and 370 series. A listing of discontinued part numbers along with a cross-reference to the new Orion Star LogR part numbers is available. Some key highlights to upgrading to the Star LogR meter are an improved LogR calibration procedure; the Orion Star meter interface with more features and pH calibration points; the resistance display; and the 3-year replacement warranty.
Chlorimeter Has Many Test Options

The new Orion AQ3070 AQUAfast Chlorine meter offers simple operation with multiple test options. The meter is designed for use with the EPA-approved Orion AQUAfast AC4P71 Free Chlorine and AC4P72 Total Chlorine Methods for drinking water and wastewater reporting. The meter will read up to 4.0 mg/L for chlorine with a single reagent pack. Although EPA reporting is from 0.02 to 2.00 mg/L, the additional range gives the user a quantitative status of his process – without re-sampling or retesting.

Chlorine Dioxide, Cyanuric Acid, and pH calibration curves are also programmed into this meter. This offers users flexibility and cost savings by using just one meter if these tests could also be needed. The AQ3070 chlorine meter is supplied in a field carrying case along with test vials, a vial cleaning brush, tablet-tamping stir rod and 100 each of AC4P71 and AC4P72 powder reagent packets.
