Real-World Testing: Putting Thermo Fisher Scientific ORION ROSS Combination pH Electrodes, Semi-Micro, Glass Body, Thermo Fisher Scientific Scientific 8103BNUWP to the Test

First Use Experience

My first field test took place during a week-long wilderness survival course in the Ozark Mountains. I used the Thermo Fisher Scientific ORION ROSS Combination pH Electrodes to analyze soil samples from various locations, assessing their suitability for growing edible plants. The electrode was submerged in water samples from a nearby stream to evaluate potability.

Even in the humid, fluctuating temperatures of the Ozarks, the electrode provided surprisingly stable readings. The semi-micro design proved invaluable when testing limited-volume samples gathered from rocky terrain. There was a slight learning curve in calibrating the electrode with the Thermo Fisher Scientific pH meter before use, but the included instructions were clear and concise.

Extended Use & Reliability

After several months of regular use, the 8103BNUWP has proven to be a reliable and durable piece of equipment. I’ve used it extensively in my own greenhouse, monitoring nutrient solutions, and it consistently provides accurate readings. I did observe some minor etching on the glass body after prolonged exposure to highly acidic solutions, but this didn’t seem to affect performance.

Cleaning is relatively straightforward; a simple rinse with distilled water after each use is usually sufficient. Compared to previous, less expensive pH electrodes I’ve used, the Thermo Fisher Scientific ORION ROSS Combination pH Electrodes offers significantly faster response times and more consistent readings across varying temperatures. It’s a marked improvement.
