## Overview

The RELD Professional Cylinder Head Gasket Tester uses advanced CO2 reaction fluid technology to quickly and accurately detect leaks in cylinder heads and gaskets across a wide range of vehicles. With 99.9% efficiency and up to 100 tests per kit, it empowers professionals and enthusiasts alike to perform cost-effective, on-the-spot diagnostics without mechanic visits.

## Description

The RELD tester is used to detect damage to the cylinder head and cylinder head gasket of liquid-cooled internal combustion engines (petrol, diesel, LPG). The tester has the same principle of operation and efficiency as expensive testers and its price is affordable due to the innovative production method. In the event of a damaged seal under the cylinder head or damage to the cylinder head itself, part of the exhaust gas contains, among other things, CO2, which now enters the cooling system. The operating principle of the device is based on measuring the CO2 concentration. As the concentration increases, the reaction liquid reacts with the CO2 and changes its colour. The set includes: Universal adaptor. Bayonet adapter (diameters: 40, 47 and 55 mm) 2 x RELD reaction fluid with a size of 250 ml (total 500 ml). You only need 5ml of reaction fluid to perform a test. Up to 100 tests can be carried out with this kit. We attach a universal adapter to our RELD tester, which has a wide measuring range (25-55 mm). Check among other things: cars, trucks, tractors, excavators, motorcycles, forklifts. The RELD reaction fluid is blue. If the liquid has not changed color after completing all the steps described in the instruction manual and is always blue, this means that your cylinder head gasket and cylinder head are in good condition. RELD reaction fluid is yellow or green If the liquid changes from blue to yellow or green after performing all the steps of the instruction manual, this means that the cylinder head gasket or cylinder head is damaged.
