Leak Detector Testo 316-4 kit 1

The Testo 316-4 kit 1 leak detector is a professional-grade instrument designed for quick and reliable leak detection in refrigeration systems and heat pumps. With its high sensitivity of <3 g/a (as per EN 14624), it ensures even the smallest leaks don’t go unnoticed—protecting both the environment and your customer’s equipment from potential damage and efficiency loss.

This all-rounder detects all common refrigerants, including R134a, R22, R404A, H₂, CFCs, HCFCs, and HFCs, and can be optionally upgraded with a sensor head for ammonia (NH₃). The flexible 370 mm gooseneck allows the sensor to be precisely positioned around pipework and hard-to-reach areas for accurate leak detection.

The sensor is self-monitoring, immediately alerting the user to malfunctions or contamination without needing external test leaks. It’s also easily cleanable and ready for use again within moments. A drag pointer function helps identify the highest concentration point, making pinpointing leaks more efficient.

Visual and audible alarms make detection unmistakable: the LED display turns from green to red when a leak is detected, and an audible signal is emitted. The included earphones are especially useful in noisy environments, ensuring you’re always aware of a leak condition.

With a reaction time under 1 second, a startup time of less than 50 seconds, and a 6-hour battery life, the Testo 316-4 is both fast and reliable in the field. It’s rugged, lightweight, and easy to handle—ideal for HVAC professionals who demand dependable performance.
