The Ultraprobe 100 (UP100) Ultrasonic Leak and Mechanical Fault Detector, engineered and manufactured by UE Systems Inc. (USA), is an affordable, rugged, and exceptionally easy-to-use handheld ultrasonic inspection instrument. Purpose-designed for plant maintenance teams, energy managers, and facility technicians, it provides a practical entry point into condition monitoring and predictive maintenance (PdM) with minimal capital expenditure.

Weighing just 11 oz (0.32 kg) in an ergonomic pistol-grip housing, the Ultraprobe 100 is engineered for comfortable, fatigue-free operation throughout full maintenance shifts. The instrument utilizes proprietary heterodyne signal conversion circuitry to translate imperceptible high-frequency ultrasonic vibrations (generated by turbulent compressed air/gas leaks, early mechanical friction in bearings, or electrical ionization sparks) into crisp, audible audio signals heard through industrial noise-attenuating headphones, while simultaneously driving a high-visibility 8-segment red LED bargraph on the instrument body.

Key Engineering Features & Operational Advantages:
- Dedicated 35 kHz to 45 kHz Frequency Response (Centered at 40 kHz): Specifically tuned to capture the peak ultrasonic acoustic output generated by compressed air, vacuum, and gas leaks conforming to ASTM E1002 international standards. This optimized frequency bandwidth inherently blocks loud, low-frequency plant-floor background ambient noise (such as presses, compressors, motors, and fans), enabling technicians to locate subtle micro-leaks without manual frequency adjustment.
- Intuitive 8-Position Sensitivity Dial & Dynamic LED Indicator: Features an easy-to-read, 8-position rotary sensitivity selection dial (numbered 0 to 7) paired with an instantaneous 8-segment red LED bargraph. Technicians simply point the sensor towards the test area, adjust the sensitivity dial to bring the signal into mid-range, and follow the escalating signal intensity to zero in on the precise leak orifice or mechanical anomaly.
- Long-Lasting 9V Alkaline Battery Power: Operates on a standard, universally available 9-Volt alkaline transistor battery. Advanced energy-efficient circuitry yields up to 45 hours of continuous field testing on a single battery, eliminating downtime associated with proprietary chargers and flat rechargeable cells.
- Versatile Quick-Connect Modular Probes:
  + Trisonic Scanning Module: Equipped with a phased array of three piezoelectric ceramic crystals, offering a broad acoustic pickup angle to detect airborne ultrasound (compressed air, gas, vacuum leaks, and electrical arcing).
  + Stethoscope Contact Module: Functions as a precision mechanical acoustic waveguide, transferring structure-borne ultrasound directly from enclosed mechanical components (bearings, steam traps, gearboxes, and pipeline valves).
  + Rubber Focusing Probe: Slips directly over the scanning module to shield stray lateral ultrasound and narrow the reception cone, enabling precise pinpointing of adjacent leaks in crowded piping manifolds.
- Rugged, Industrial-Grade Construction: Enclosed in high-impact industrial ABS resin designed to resist drops, mechanical shocks, dust, and workshop grease, ensuring dependable field operation in heavy manufacturing, paper mills, foundries, food processing, and chemical facilities.

Typical Industrial Applications:
- Compressed Air, Inert Gas & Vacuum Leak Auditing: Swiftly pinpoints threaded joints, quick-disconnect fittings, flexible hoses, valves, and regulator leaks, saving thousands of dollars in compressor electrical energy costs annually.
- Steam Trap Testing & Pipeline Valve Inspection: Listens to and verifies steam trap cyclic operation (opening, discharging, shutting); identifies traps blowing live steam or stuck shut (causing condensate backup); inspects shut-off valves for seat bypass leakage.
- Bearing Condition Monitoring & Basic Lubrication Testing: Detects high-frequency friction hiss caused by lack of lubricant; warns of early ball and race micro-pitting long before mechanical vibration or temperature spikes occur.
- Electrical Substation & Switchgear Safety Inspection: Detects electrical arcing and surface tracking faults in distribution panels, motor control centers (MCC), fuse blocks, and circuit breakers.
- General Enclosure Tightness Testing: Pairs with an ultrasonic tone generator (such as the WTG-1) to verify seal integrity in automotive cabins, cleanrooms, and cargo hatch covers.
