PCE Instruments PCE-HLD 10 Leak Detector, for Hydrogen Leak Testing, Measures <5 ppm (5% H2/N2), Sensitivity >2/15/30 g/yr, 40 cm Probe, Traffic-Light bar, Audible/Visual Alarm, ~12 h Battery

The PCE-HLD 10 Leak Detector from PCE Instruments is a sophisticated tool designed for precise leak detection using hydrogen technology. This device features a hydrogen-selective sensor that can detect extremely small leaks with very low leak rates. The detector works by automatically recording the current hydrogen concentration in the environment when switched on, then evaluating changes relative to this baseline. With three adjustable sensitivity levels (High, Medium, Low), this detector can recognize hydrogen concentrations of less than 5 ppm (0.0005 percent). The sensor is positioned at the head of a semi-rigid 40-centimeter hose for easy access to test components. When a leak is detected, the device alerts you with an alarm tone and indicator LEDs that increase in number as hydrogen concentration rises. Powered by four standard batteries providing approximately twelve hours of operation, the PCE-HLD 10 includes an automatic shut-off feature after ten minutes of inactivity to conserve power. Made in Taiwan and backed by a 2-year warranty, this leak detector is an essential tool for professionals requiring precise gas leak identification.

• HYDROGEN DETECTION: Specialized gas leak detector with hydrogen-selective sensor capable of detecting concentrations as low as 5 ppm (0.0005%) for precise leak identification.
• ADJUSTABLE SENSITIVITY: Features three sensitivity levels (High, Medium, Low) with LED indicators and alarm system that activates when hydrogen is detected above baseline levels.
• FLEXIBLE DESIGN: Equipped with a semi-rigid 40 cm hose and sensor head for easy access to hard-to-reach testing areas and components.
• PRACTICAL FEATURES: Includes automatic environmental calibration, reset function for better leak localization, and automatic power-off after 10 minutes to conserve battery life.
• LONG-LASTING PERFORMANCE: Operates for approximately 12 hours on four standard batteries with a sensor that maintains reliability for over a year under normal use conditions.
