## Long description

The Jonnesway AR030002 handheld coolant tester is a compact instrument for quickly assessing engine antifreeze condition. It measures refractive properties to estimate coolant concentration and provides an acid check to detect pH imbalance or contamination. The device is designed for portable use in workshops, service vans, or roadside inspections, enabling technicians and vehicle owners to evaluate freeze and boil protection as well as general cooling system health.
Advantages
The tester offers rapid, on-the-spot readings without the need for complex setup, combining refractive measurement and acidity assessment in a single handheld unit. Its simple operation and durable construction make it suitable for frequent use during scheduled maintenance or troubleshooting. The compact size and lightweight design facilitate storage in a toolbox or glove compartment, while the clear scale and straightforward procedure reduce the chance of user error.
Suitable for
Routine maintenance checks of engine coolant concentration
Pre-trip or roadside inspections to verify freeze and boil protection
Workshop diagnostics to detect coolant contamination or acidification
Fleet maintenance programs requiring quick, repeatable checks
Key specifications
Handheld refractometer-style device for estimating coolant concentration
Acidity (pH) check function to identify acidification or contamination
Portable, lightweight construction suitable for field use
Clear, direct-reading scale intended for fast interpretation
Designed for use with ethylene glycol and propylene glycol based antifreeze
How to use
To use the coolant tester, obtain a small sample of coolant from the radiator or expansion tank when the engine is cool. Place the sample on the measurement prism or sensor area according to the included instructions and activate the device if required. Read the refractive scale to estimate freeze/boil protection and consult the acidity indicator to detect possible acidification. Dispose of used fluid sample safely and wipe the device clean after each test to maintain accuracy.
Usage recommendations
Perform testing when the engine is cool and follow vehicle manufacturer guidelines for coolant type and maintenance intervals. Use the tester as a screening tool—if readings indicate low concentration, contamination, or abnormal acidity, follow up with laboratory testing or professional inspection to confirm the condition and determine corrective actions.
