Fieldpiece SRL2K7 Infrared Refrigerant Leak Detector Kit — HVAC-R

Built for sparkies and fridgies who need results, fast. The Fieldpiece SRL2K7 is a pro-grade infrared refrigerant leak detector designed for dependable, repeatable leak finds on site. It’s rugged, easy to use, and helps you nail the job first time — fewer call-backs, more billable work. Too easy.

Key Features & Trade Benefits

• Infrared sensor (10-year design life) – stable sensitivity over time for reliable finds season after season.
• High sensitivity (≤ 0.1 oz/yr ≈ 3 g/yr) – pinpoints micro-leaks other sniffers miss, so you can stop “she’ll be right” returns.
• Detects CFC, HCFC, HFC & blends – covers common refrigerants you see day-to-day in Aussie HVAC-R.
• Fast response (~1 s) & recovery (~4 s) – sweep faster and confirm repairs without waiting around.
• Audible + visual indication with Peak/Mute – chase leaks in noisy plantrooms and rooftops without losing the signal.
• 8-hour rechargeable Li-ion runtime – work a full day; charge in the ute between jobs (≈ <4 h charge).
• Doesn’t false-trigger on oil or moisture – fewer “ghost” alarms, better decisions on the tools.
• Rugged, ergonomic body + magnetic hanger – tough kit that hangs nearby while you braze or tighten.

Why This Detector Matters

Real-world scenario: you’re up on a roof in 40-degree heat, condenser screaming, head pressure high, client pacing. With the SRL2K7’s rapid response and stable IR sensor, you sweep the coil returns, TXV and flare joints, peak the signal and bang — tiny leak, found and fixed. Fair dinkum time saver.

Pro Tip

Protect the sensor and improve repeatability: replace the tip filters regularly and use the Peak function to lock the highest reading as you triangulate. Use standard sensitivity for initial sweeps, then bump to high only when you’re close. Keep the probe steady and avoid draughts for the most accurate sniff.

Compatibility & System Info

• Refrigerants: Triggers on CFC, HCFC, HFC and blends (e.g., R134a, R410A, R404A, R22 replacement blends).
• Use cases: Residential and light commercial HVAC-R, supermarket cases, chillers and split systems.

Note: For current-gen IR detection including HFOs/A2L workflows, consider the newer Fieldpiece DR82. Here’s the DR82 option.

Local Jobsite Edge

From humid Brisbane summers to hot, dusty Perth rooftops, the SRL2K7’s rugged build and long runtime mean fewer breaks and no dramas on site. Keep it in the case; it’ll cop a fair bit of abuse and keep going.

FAQs

Q: Will SRL2K7 pick up tiny leaks around TXVs and flares?
A: Yes — its IR sensor and ≤0.1 oz/yr sensitivity are designed for micro-leaks. Use Peak to lock readings and the flexible probe to sneak behind tight bends.

Q: Does it false-trigger on oil or moisture?
A: No — unlike some heated-diode/corona styles, the SRL2’s IR design won’t trigger on oil or moisture, giving you cleaner calls.

Q: Is this suitable for current A2L workflows?
A: SRL2 covers CFC/HCFC/HFC and blends. For HFO/A2L-focused work, check the newer DR82 IR detector. See DR82 here.

Q: How often should I replace filters?
A: Inspect regularly; swap when the hydrophobic filter swells or airflow drops. Grab a pack of RFL2 filters & O-rings.
