What is the CPS LS790B Leak-Seeker?
The CPS LS790B Leak-Seeker is a professional-grade electronic refrigerant leak detector that’s designed to find even the smallest refrigerant leaks in HVAC, refrigeration, and cooling systems.
It uses advanced heated-diode sensor technology, providing the sensitivity that technicians need to detect leaks of modern HFC, HCFC, CFC, and blended refrigerants.
Its ergonomic design, combined with a flexible probe and instant-response mechanism, offers a reliable tool for routine inspections, service calls, and preventive maintenance.
Key Features of CPS LS790B Leak-Seeker
1. High-Sensitivity Heated Diode Sensor
The LS790B features an advanced heated-diode sensor with high sensitivity, offering leak detection as low as 0.1 oz/year. This ensures accurate detection in low-level leak conditions.
2. Compatible with Multiple Refrigerants
It can handle a wide variety of refrigerants, including:
- CFCs (R12, R11)
- HCFCs (R22)
- HFCs (R134a, R410A, R407C)
- Blended refrigerants used in modern systems
This makes it suitable for various system types across commercial, marine, and industrial sectors.
3. Adjustable Sensitivity Levels
With various sensitivity modes, technicians can adjust the levels of detection based on the environment, therefore reducing false alarms and improving accuracy.
4. Flexible Probe for Hard-to-Reach Areas
