3-Star meters now include an improved stability algorithm to increase calibration and measurement accuracy. Meters can now be paired with auto-samplers for increased sample throughput. Increased memory allows you to log more data points and even turn off the data log if desired. Improved security is offered by new individual methods passwords. Temperature accuracy can be ensured with the ATC temperature calibration feature.
All Orion Star Series meters include a convenient Quick-Start guide to help you get started and provide support while in use. Smart Stability™ and Smart Averaging™ ensure accurate results. GLP-related features including datalogging with time/date stamp and electrode verification. Meters feature automatic or manual pH calibration, auto-buiffer recognition, advanced self-tests and self-diagnostics, and RS-232 or optional USB connectivity.
3-Star meter only includes: Quick-Start guide and AC power supply.
3-Star meter kit adds: ROSS Ultra® Triode™ pH/ATC electrode, buffers (pH 4.01, 7.00, and 10.00), pH electrode storage solution, and benchtop electrode stand.

Q:In relation to my last question; I tried using the Data log and it printed off fine. However, when I took the measurement the slope result at the bottom I.e. Where my sample result is, is different to the slope I used to calibrate the meter in the morning. For example, calibrated between 4-7 and slope was 98.7. When I returned in the evening, retrieved calibration from logger and measured the sample my slope was 99.4. Is this ok? Someone could have used the meter after me in the morning, but if I picked my own calibration I presumed this would be OK?
A:A slope between 95-101% is considered very good.
Q:Hi, my query is regarding calibration of orion 3 star ph meter. we generally use 3point calibration,after completion of calibration,slope was with in limits and display shows man 4 7 only without 10. we are doing 4,7,10 buffers for calibration.why this was appearing, can u pls say why the display is so.
A:Please try resetting your unit:
Q:Can this model be connected to the computer for data logging? if yes, how it can be connected and what software can be used?
A:Yes, there is an RS-232 port on the meter that will allow you to connect to a computer. The cables are available in the accessories section of the web page. This will download the stored data into an Excel spreadsheet.
