Antifreeze pH Meter — protecting modern engines and EV cooling systems from hidden corrosion
Thursday 04 December 2025
In the past, checking coolant condition was as simple as confirming its freezing point. But today’s advanced petrol, diesel and EV cooling systems demand more — acidity levels (pH) must be monitored to prevent internal corrosion, premature component wear, and costly failures. That’s why Laser Tools has introduced the Antifreeze pH Meter (part number 9193), a compact and waterproof digital tester designed to make quick, reliable pH checks part of routine maintenance.
As antifreeze and coolant fluids age, their chemical stability breaks down, increasing acidity and accelerating corrosion inside the cooling system. By testing pH directly, the 9193 provides an accurate picture of coolant health, giving technicians — and conscientious vehicle owners — confidence that engines are properly protected.
Key features:
- Versatile applications: suitable for cars, vans, HGVs, agricultural machinery, EV cooling systems — as well as non-automotive uses like water treatment, hot tubs, and aquariums.
- Professional accuracy: measuring range 0.00–14.00 pH; resolution 0.01 pH; accuracy ±0.1 pH. Auto temperature compensation between 0–50°C ensures consistent results.
- Practical design: waterproof pen-style tester with digital temperature display. Calibration solution included.
- Clear benchmark: most automotive coolants should remain above pH 7.5 — always check the vehicle manufacturer’s data for the correct specification.
- Ready to use: powered by 4 × 1.5V LR44 batteries (included). CE & RoHS compliant.
The Laser 9193 Antifreeze pH Meter is a quick, affordable and effective way to safeguard engines — from family cars to heavy goods vehicles and agricultural machinery — against avoidable damage caused by neglected coolant.
