• 【Pro-Grade Accuracy】Advanced heated diode sensor detects leaks 20x more precisely than soap bubble methods (0.1oz/yr sensitivity), pinpointing even microscopic refrigerant leaks in HVAC/R systems, automotive AC units, and commercial refrigeration.
• 【Smart Digital Display & Alerts】Real-time numerical readout with 0.01oz resolution dual warning system (90dB buzzer & LED alerts) ensures reliable leak detection in noisy workshop environments.
• 【3-Mode Sensitivity Control】Optimize detection with High/Medium/Low settings - perfect for tracing leaks in complex systems from residential heat pumps to industrial chillers (R410A/R22/R404A/R134A/R1234YF compatible).
• 【Engineer-Approved Design】One-touch mute button & ergonomic controls allow gloved operation. 30-second warmup ready for instant leak checks - complete 3x faster than conventional detectors.
• 【Universal Refrigerant Coverage】Detects ALL halogen-based coolants: CFCs, HCFCs, HFCs, HFOs (including newer R1234YF) blends like AZ-50/MP39. certified sensor responds in <1 second with zero false positives. Powered by 4x AA batteries (included).
