The JB Industries LD-5000 PROWLER is a revolutionary refrigerant gas leak detector designed for unparalleled accuracy and user-friendly operation. It utilizes proprietary JB Industries Electrochemical sensor technology to detect a wide range of refrigerants, including HFCs, HCFCs, HFOs, and SNAP approved blends.
Function Description:
The PROWLER LD-5000 is a handheld probe-type service leak detector that identifies refrigerant gas leaks. It features a long-life electrochemical sensor that is highly sensitive to various refrigerants, including R-134a, R-410A, R-404A, R-407C, R-507, R-22, R-427A, and R-1234yf. The sensor is durable and resistant to damage from overexposure to refrigerant gas or condensate water. It boasts low battery consumption, excellent circuit stability, and an exceptionally long sensor life, tested to be greater than ten years. The device is safe for use in combustible atmospheres.
When a leak is detected, the PROWLER provides multiple alerts: an audible alarm, vibration in the handle, and a bar graph on the LCD screen indicating leak intensity. The unique digital leak size indicator helps users determine the severity of a leak, eliminating guesswork about whether a small leak needs repair. The adjustable LCD display allows for precise pinpointing of the leak source, independent of audio/vibration alarms and sensitivity levels.

Usage Features:
- Power On/Off: Press the ON/OFF button once to turn on and again to turn off. Holding the button for approximately 1 second turns the unit off.
- Warm-Up Mode: The detector automatically conditions the sensor upon startup, typically taking less than 20 seconds. A slow "beep" sounds, and the digital graph leak size indicator gradually increases until all 10 bars are displayed, signaling readiness.
- Sensitivity Levels: The unit defaults to MED sensitivity after warm-up. Users can adjust sensitivity to HI or LO by pressing the Sensitivity button.
- Leak Size Indicator: A digital graph display with up to 10 bars (increasing height) indicates leak size. This helps approximate leak severity: 1-3 bars (<0.1 oz/yr), 4-6 bars (0.1 - 0.5 oz/yr), and 7-10 bars (>0.5 oz/yr).
- Adjustable LCD Display: The LCD screen flips upward, allowing users to adjust the viewing angle (up to 30 degrees) for better visibility.
- Backlight: A backlight button allows users to turn the LCD display backlight on or off for low-light conditions.
- Auto Mute Function & Vibrating Handle: The MUTE button silences the audible alarm. The vibrating handle mode is always on, providing tactile feedback for leak detection, especially useful in noisy environments or when the audio is muted.
- Automatic Calibration Mode: This default mode automatically recalibrates (re-zeroes) to ambient levels, stopping constant alarms and responding only to higher refrigerant levels. The detector resets automatically after 3-4 seconds.
- Manual Calibration Mode: For more control in heavily contaminated areas or when searching for smaller leaks, users can enter manual calibration mode. In this mode, the detector recalibrates only when the user chooses to do so by pressing and holding the Sensitivity button until the indicator flashes. The alarm can be reset by pressing the Sensitivity button again.
- Leak Test Vial: The PROWLER includes a Leak Test Vial to verify proper sensor and electronics function. Users remove a seal, turn on the detector, allow it to warm up, and place the sensor near the vial's hole. An increase in beep rate and a minimum of 3 bars on the Digital Leak Size Indicator Graph confirm functionality.
Maintenance Features:
- Batteries: The device operates on 4 AA Alkaline batteries (included). To install/replace, remove the screw on the bottom housing, remove the battery door, and insert batteries according to polarity marks inside the compartment.
- Sensor Filter Replacement: The sensor tip can be unscrewed to replace the filter. Filters should be replaced when visibly dirty or every 2-3 months, depending on usage.
- Sensor Replacement: The sensor is removed by pulling it straight out of its socket. A new sensor is installed by aligning the notch in the sensor socket with the raised tab on the sensor and pushing it straight in. It is crucial not to twist the sensor or force it into the socket to avoid damaging the sensor pins. Proper insertion is vital for operation; a loose or improperly inserted sensor will keep the detector in warm-up mode.
Certifications:
The PROWLER LD-5000 is certified under CE, ASHRAE 173-2012, EN 14624:2012, SAE J2791, and SAE J2913 standards.
Warranty:
The product comes with a 24-month warranty covering defects in materials and workmanship from the date of purchase. This warranty applies to all repairable instruments that have not been tampered with or damaged through improper use, including unauthorized opening of the unit.
