This is the Testo pH2 spare probe, specifically designed for your Testo 206 pH/temperature measuring instrument. It ensures you can keep your readings accurate and reliable, whether you're checking water quality in hydronic systems or other process fluids.

Anyone who's relied on a pH meter knows that probe lifespan isn't forever, and having a fresh one ensures your measurements stay spot on when it counts, especially when you're out on a job and can't afford downtime.

Best For

• HVAC techs monitoring water quality in cooling towers or hydronic loops.
• Service technicians needing reliable pH measurements for various applications.
• Anyone looking to replace a worn or damaged pH probe on their Testo 206.

Compatibility

This pH2 probe is engineered specifically for the Testo 206 pH/temperature measuring instrument. It's not a universal probe, so make sure your existing meter is a Testo 206 before ordering.

If you're running a different model, check fittings and specs before ordering.

Features

• Easy Replacement: Designed for quick and straightforward change of the measuring tip, getting you back to work fast.
• Integrated NTC Temperature Sensor: Provides accurate temperature compensation for more reliable pH readings.
• Gel Storage Cap Included: Keeps the probe moist and ready for use, extending its lifespan and maintaining accuracy.
• Robust Construction: Built to withstand typical field conditions, offering consistent performance.

Technical Specifications

What's in the Box

• 1 x Testo Spare pH probe pH2 (0650 2062)
• 1 x Gel storage cap

Using It on the Job

1. Inspect & Prepare: Before use, visually check the probe tip for any damage. Ensure the Testo 206 instrument is clean and ready.
2. Swap the Probe: Carefully unscrew the old pH probe from your Testo 206. Screw the new pH2 spare probe firmly into place, ensuring a snug connection.
3. Calibrate Your Meter: Always calibrate your Testo 206 with fresh buffer solutions after changing probes to ensure maximum accuracy. Follow the instrument's manual for proper calibration procedure.
4. Take Readings: Immerse the probe tip in the sample liquid, ensuring the sensor is fully submerged. Wait for the reading to stabilise before recording.
5. Clean & Store: After each use, rinse the probe with distilled water. Always store the probe with its gel storage cap filled with appropriate storage solution to prevent drying out and extend its life.

Limitations & Safety Notes

• This probe is specifically designed for the Testo 206 pH/temperature measuring instrument. It is not compatible with other pH meters.
• Avoid exposing the probe to temperatures outside its specified operating range for prolonged periods, especially the short-term maximum of +80 ℃.
• Do not use the probe in highly viscous or abrasive media that could damage the glass membrane or diaphragm.
• Always store the probe with the gel cap containing storage solution to prevent the electrolyte from drying out, which can permanently damage the sensor.

Tradie Pro Tip

Don't skimp on calibration. Even with a new probe, an uncalibrated meter is just guessing. Always use fresh, high-quality buffer solutions and calibrate regularly, especially if your readings are critical or the environment changes often.

Pair With

This spare probe is an essential partner for your Testo 206 pH/temperature measuring instrument. Consider also stocking up on Testo calibration solutions and electrode cleaning solutions to maintain peak performance and extend the life of your probes.
