Rugged and easy to use, LACO’s Helium Spray Probes are designed for use in maintenance or production leak detection applications. Our helium spray probes include up to 10 ft. of poly hose with a stainless steel flexible probe and a rigid SS probe. They are stored in a durable storage case. The LHSP07 Helium Spray Probe also features a refillable reservoir for convenient transportation to any location without taking a helium bottle. All spray probes are compatible with an optional helium tank regulator for immediate connection to your helium bottle.
