Photometer FAQs
What is a photometer?
A water photometer is a digital device used to measure the concentration of chemicals in your pool by analysing colour intensity. Unlike manual kits, a photometer palintest removes human error and "colour matching" guesswork, providing highly accurate results.
What do Photometers test for?
Depending on the model, water photometers can test for:
- Free and total chlorine
- pH level
- Alkalinity
- Calcium hardness
- Cyanuric acid (stabiliser)
- Bromine, iron, copper, phosphates (advanced models)
Results are typically shown on an LCD screen within seconds.
Why do I need a swimming pool photometer?
A photometer provides lab-quality digital accuracy - ensuring the safety of your pool water.
Do I need a hot tub photometer?
Yes - accurate chemical readings are especially critical in hot tubs, where small water volumes and high temperatures cause rapid, dangerous chemical shifts.
What is the eXact iDip system?
The eXact iDip is a smart photometer that connects directly to your smartphone or tablet via Bluetooth. It allows you to track historical data, calculate the Langelier Saturation Index (LSI), and share results instantly, making it a favourite for modern pool professionals.
Are swimming pool photometers better than standard test strips?
While pool test strips are great for quick checks, a digital water photometer is essential for precision. If you are balancing a complex setup or troubleshooting water clarity issues, the accuracy of a photometer palintest or eXact iDip is unmatched.
How often should I calibrate my photometer?
To maintain accuracy for your pool photometer, we recommend regular calibration as per the manufacturer's guidelines.
