FLD-HCSP is a miniature leak detection probe that is fully encapsulated. This high-performance sensing probe is designed for detecting leaks of refined products or crude oil in challenging small space locations where regular sensing probes may not be suitable. This probe can also be used as a cost-effective zero-false-alarms hydrocarbon fumes detector. Encased in a corrosion resistant stainless steel slotted cylinder, it is specially engineered for reliable operation in tank interstitial space, machine shafts, pumps, etc. The length of the probe is 3.74" (95 mm), with a diameter of 0.59" (15 mm). This sensing probe can be wired to the acquisition module through an optional jumper cable with a maximum length of 300 ft (90 m).
Advanced measurement techniques and PHMSA compliant leak detection algorithms are used by Naftosense acquisition modules to provide quick detection in a very wide temperature range. The sensing probe is cleanable and reusable with optional connectors for quick disconnection for cleaning.
FLD-HCSP probe is designed to be used exclusively with acquisition modules or intrinsically safe field boxes offered by Naftosense providing industry-standard analog outputs, dry contacts or serial communication protocols for flexible integration with third-party monitoring panels or PLC.
FLD-HCSP is a passive simple element and is safe for installations in hazardous locations when connected to intrinsically safe field box or wired through an approved Zener barrier to acquisition modules, alarm panels or other monitoring equipment installed in the safe area.

| Typical Detection Times | |
| Gasoline, Jet Fuel, Diesel | 20 to 28 seconds* |
| Light Crude Oil | 45 to 60 seconds |
| Heavy Crude Oil, Dilbit | 3 to 4 minutes |
| Motor Oil, Silicone Oil | 8 to 10 minutes |
| Propane, Butane | 25 to 30 seconds** |
* Performance metrics obtained according to the testing procedure depicted in the FM7745 standard.
** When detecting vapors/LPG, the sensing probe must be placed in the lowest point where the fluid will accumulate.
