POROMETISTO HLD01 Halogen Refrigerant Leak Detector – Rechargeable USB-C, Flexible Probe & High-Precision Chips

The POROMETISTO HLD01 is a portable 2-in-1 rechargeable halogen gas leak detector designed to quickly find and quantify refrigerant leaks with adjustable sensitivity and visual alerts.

This compact instrument combines precise sensing chips with user-friendly controls and a long flexible probe to help technicians inspect refrigeration and HVAC systems. Built-in LED auxiliary lighting, a color-coded LCD readout and two calibration modes let you adapt readings to workplace conditions, while USB-C rechargeability keeps the unit ready on the job. It detects a broad range of common refrigerants across CFC, HCFC, HFC and HFO families.

How accurate is the HLD01 for locating refrigerant leaks?

The HLD01 uses high-precision sensing chips and offers two sensitivity levels for coarse or fine detection, giving reliable results from small leaks up to higher concentration levels. The calibrated measurement range and automatic/manual calibration option help improve repeatability across different environments.

• Measurement range: approximately 16–200 ppm for detected gases.
• Sensitivity toggle (S-HI / S-LO) for rapid sweep or targeted pinpointing.
• Automatic and manual calibration modes to reduce false readings.
• Three-color LCD alarm for quick status interpretation (green/yellow/red).

What gases can this detector identify and how versatile is it?

POROMETISTO engineered the HLD01 to respond to many refrigerant classes used in HVAC and refrigeration. The detector covers multiple CFCs, HCFCs, HFCs and modern HFOs, making it suitable for service work across legacy and newer systems.

• Compatible gas families: CFC, HCFC, HFC, HFO (wide list of common refrigerants).
• Includes detection examples like R12, R22, R134a, R410A, R1234yf and others.
• Single-device solution for mixed fleet or retrofit systems.
• Useful for inspections, maintenance checks and leak verification after repairs.

Which features improve on-site usability and safety?

The unit was designed for hands-on work: a long flexible hose extends reach into tight spaces, LEDs illuminate dark service areas, and audible/visual alarms signal unsafe concentrations. Compact build and USB-C charging let technicians keep the tool powered without specialized batteries.

• Extended flexible probe for accessing cramped or hidden joints.
• White auxiliary LED and purple pinpoint LED for leak illumination and contrast.
• Triple alert system: sound, vibration (if present), and three-color LCD indicator.
• Rechargeable via USB-C with included cable; cloth storage bag for transport.

How easy is it to operate and maintain the detector?

Controls are straightforward so technicians can begin inspections quickly: power on, choose sensitivity, and probe suspect areas. The clear LCD displays numerical values even in sunlight or dim conditions, and the kit includes a manual and accessories for immediate use.

• Simple one-click lighting and mode switching for rapid operation.
• Clear numeric readout plus color-coded alarm thresholds for 0–16 ppm (green), 16–85 ppm (yellow), >85 ppm (red).
• Comes with USB-C cable, cloth bag and user manual for turnkey use.
• POROMETISTO provides one-year replacement coverage for manufacturing faults.

Who this is for: Professional HVAC technicians, appliance service teams and facility maintenance staff who need a portable, rechargeable detector that identifies a wide range of refrigerants and simplifies leak troubleshooting. It’s also useful for contractors managing both older and modern refrigerant types who value adjustable sensitivity, visual aids for dark environments and the convenience of USB-C recharging.
