Client: 
        Are the aqualux probes standard?
    
        Technical Advisor: 
        What do you mean by standard?
    
        Client: 
        I have an aqualux installation. I need to replace my pH probe. Is there a risk that the probe won't fit?
    
        Technical Advisor: 
        Yes. Send me a photo of your current probe, no need to remove it, I will check.
