My experience in disaster relief often requires me to quickly assess the potability of water sources. Traditional test kits are cumbersome, and subjective colorimetric readings are prone to error, so I needed a portable, accurate solution. I’d been using test strips, but their accuracy left a lot to be desired, especially at lower chlorine concentrations where disinfection efficacy is questionable.
Upon unboxing, the Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP felt robust and well-constructed. It has a solid feel, and the BNC connector is secure. The included iodide reagent and instruction manual were a welcome addition, setting me up for immediate use.
I considered the Hach CL17 and the Hanna Instruments HI96771 for chlorine measurement. Ultimately, the Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP won me over with its combination solid-state design, which promised reduced maintenance compared to membrane-based electrodes. I hoped for a more rugged and field-friendly instrument.
Initially, I was excited to see if it could deliver accurate and consistent results in challenging field conditions, specifically with minimal calibration. The promise of being able to quickly and reliably determine if water was safe to drink, without the subjective nature of test strips or color comparators, was extremely appealing.
Real-World Testing: Putting Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP to the Test
First Use Experience
My initial testing took place at a remote water treatment facility after a flash flood compromised the regular chlorination system. The conditions were less than ideal, with high turbidity and fluctuating water temperatures. I needed to quickly assess the effectiveness of emergency chlorination efforts.
The Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP proved relatively easy to use, even without extensive prior experience. After a quick calibration, I was able to start taking readings, though it did take a couple of tries to get the hang of the iodide reagent addition. The electrode seemed to stabilize quickly, providing reasonably consistent measurements.
The biggest surprise was the sensitivity of the electrode to temperature variations. A significant shift in temperature caused readings to fluctuate wildly, requiring recalibration.
Extended Use & Reliability
After several months of regular use, the Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP has proven to be a reliable tool. It requires regular calibration but maintains accuracy within the specified range when properly maintained.
While the electrode itself is robust, the BNC connector shows some wear and tear after repeated connections and disconnections. Cleaning is straightforward, requiring only a rinse with distilled water and occasional soaking in a cleaning solution.
Compared to my previous experience with colorimetric test kits, the Thermo Fisher Scientific ORION Residual Chlorine Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9770BNWP offers vastly superior accuracy and objectivity. The initial investment is higher, but the increased confidence in the results and the reduced reliance on subjective interpretation make it worthwhile.
