CARE AND USE
Properly maintaining your pH and ORP probes will give you fast, accurate results for longer. pH and ORP probes are similar in design but there are some differences.
pH probes have a sensing bulb that loses sensitivity with age. All pH sensors have a limited life and response time gets longer with age.
ORP probe have usually a platinum electrode instead of a glass bulb. This electrode has a longer life but can have a residue build up that affect response rates and accuracy.
Both electrodes have a reference junction that can become clogged resulting in slow and inaccurate results. Cleaning and keeping the probe hydrated will help prevent this.
pH Probe
Here are our top four tips for your pH probe.
1. Always store with the cap full of buffer or storage solution not water.
2. Clean your Probe regularly by soaking in cleaning solution.
3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.
4. Gently stir the Probe in the sample for a faster result.
ORP Probe
Here are our top three tips for your ORP probe.
1. Always store with the cap full of buffer or storage solution not water.
2. Clean your probe regularly by soaking in cleaning solution.
3. Calibrate after cleaning and/or storage before testing to adjust for changes in the ORP probe sensor.
