SwiftLab
A professional-grade, 7-in-1 smart testing pen that delivers instant, lab-accurate measurements for pH, TDS, EC, and more. Essential for drinking water safety, aquariums, and home brewing.
Professional Precision in Your Pocket
The SwiftLab Pro-7 Digital Water Quality Tester is engineered to bring laboratory-grade environmental diagnostics directly into your home. Equipped with an advanced titanium alloy probe and a highly sensitive glass electrode, the Pro-7 provides instant, reliable readings across seven critical water quality metrics: pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), Oxidation-Reduction Potential (ORP), Salinity, Specific Gravity (S.G), and Temperature.
Intelligent Automatic Temperature Compensation
Temperature fluctuations can drastically alter water quality readings. The Pro-7 features built-in Automatic Temperature Compensation (ATC) ranging from 0.1°C to 60.0°C. This ensures that your measurements are automatically adjusted for temperature variances, providing you with consistent and highly accurate data regardless of the testing environment.
Built for Everyday UK Life
Whether you are maintaining a delicate marine aquarium, optimising nutrient solutions for hydroponics, or simply testing the hardness of your tap water, the Pro-7 is designed for effortless operation. It boasts an IP67 waterproof rating, meaning it can withstand accidental submersion, while the high-contrast backlit LCD ensures your readings are clearly visible even in poorly lit spaces like under-sink cupboards or dimly lit sheds.

How to Use
- Remove the protective cap from the bottom of the tester.
- Press the power button to turn on the device.
- Immerse the electrode into the water sample up to the maximum immersion line.
- Stir gently and wait for 3-5 seconds until the reading on the LCD screen stabilises.
- Press the 'MODE' button to cycle through pH, TDS, EC, and other metrics.
- After use, rinse the electrode with distilled water, dab dry with a tissue, and replace the protective cap.
Customer Reviews
I use this daily for my indoor hydroponics setup. The pH accuracy is spot on compared to my old, much more expensive lab meter, and the backlit screen makes it so easy to read inside the grow tent.
Sarah Mitchell, London
Brilliant bit of kit. Delivery was incredibly fast. I bought it primarily for my tropical aquarium to keep an eye on the TDS and temperature. It takes all the guesswork out of water changes.
James Henderson, Manchester
As an environmental consultant, I appreciate the build quality of the titanium probe. It stabilises very quickly and the automatic temperature compensation works flawlessly. Highly recommended for field checks.
Dr. Emily Clarke, Edinburgh
Very accurate once set up. The initial 3-point calibration takes a couple of minutes and requires distilled water which isn't included, but once that's done, it performs exceptionally well.
Oliver Wright, Bristol
I bought a cheap generic tester from Amazon before this and it broke in a week. The SwiftLab Pro-7 feels much sturdier, and the 7-in-1 functionality means I don't need multiple pens cluttering my drawer.
Rebecca Thompson, Leeds
Great tool for my home brewing. The salinity and pH readings are vital for my mash. Only dropping a star because the battery compartment cap is quite stiff to unscrew the first time.
David Patel, Birmingham
Fantastic value for money. We live in a hard water area and this has been invaluable for testing our tap water before and after installing a water softener. Clear, instant results.
