What pH sensor is right for me?
For most applications the standard pH probe will suit. For food and slurry type applications we would recommend the Premium pH sensor. It can be partially taken apart, cleaned and refilled with reference solution. We also have pH sensors to suit being fully submersed up to 20m as well as high temperature applications.
My pH sensor isn't reading right, what do I do?
Always calibrate to the instrument you are using. Check the glass tip has not dried out. An overnight soak in pH storage solution can do wonders. Check there is no air bubble in the tip. If all this fails send it to us for service.
How should I care for my pH sensor?
Treat it carefully and clean with DI water after every use to prevent blockage to the porous junction.
My pH sensor is reading very slowly, what does that mean?
It could be blocked or low on internal gel solution. If so it might be time for a new sensor.
How should I store my pH sensor?
In its box in a dry area. Ensure the end cap is fitted with a couple for drops of pH storage solution the keep the glass tip moist.
What is K factor?
The K factor refers to the range at which a given sensor can best perform. K=0.1 for very pure water. K=1.0 for tap or fresh water. K=10 for seawater or process water
How should I clean my Conductivity sensor?
Just rinse carefully with DI water. The platinum plates are very sensitive to being scratched or worn, so no scrubbing!
Can I connect my monitor to a computer to downlaod the data?
Yes. If you have a WP or 90 series monitor you have the option to order a USB cable to connect to a Windows computer. You can order our software on a USB or download from our website.
Do you sell pH buffer?
Yes. We stock a full range of buffers and solutions for all our sensors.
