Product Details

RECHARGEABLE LITHIUM BATTERY: A 2500mAh built-in lithium battery delivers up to 24 hours of continuous work on a single charge, so the detector is ready whenever a call comes in. Charges from any USB-C power source; cable included. No disposable batteries to buy or carry.
HIGHLY SENSITIVE SENSOR: Japanese-made metal-oxide semiconductor sensor responds to the full halogenated refrigerant family, with selectable High and Low sensitivity so you can sweep an area broadly first, then switch down to close in on the exact joint.
BEFORE YOUR FIRST JOB: Like all metal-oxide sensors, this detector reaches full sensitivity after running for several hours - leave it switched on in clean air when it is new or has been in storage. In use, switch it on in clean air away from the leak, then move the probe no faster than 1 inch (25 mm) per second, about 1/4 in from the joint, with fans and drafts off. This is what separates a found leak from a missed one.
BROAD RANGE DETECTION: SFD200 responds to the full halogenated refrigerant family - CFCs: R11 R12 R113 R114; HCFCs: R21 R22 R31 R121 R122 R123 R124 R141b R142b R401a R402a R402b R408a R409a R509a; HFCs: R23 R32 R41 R125 R134a R143a R152a R404a R407c R410a R417a R507 R508a R508b; HFOs: R-1234yf R-1234ze R449a R452b R454a R455a R456a R457a R459a, and more - covering home and commercial air conditioning, refrigeration and automotive AC. If you also need to check natural gas, LPG or propane lines, choose the SFD201 model on this page.
LIVE PPM READING: A large color LCD shows the actual concentration in ppm plus a bar graph, so you can watch the number climb and narrow down to the exact joint instead of guessing from faster beeping. The buzzer follows the reading as well and can be muted when you need to work quietly.
US-BASED CUSTOMER SERVICE: We provide responsive and dedicated customer service along with technical support, all based in the US. Our team is ready to assist you with any questions or needs you may have, ensuring a smooth experience with our products.
⚠️ WARNING: Prolonged exposure to certain refrigerants may cause health issues, including headaches, dizziness, and respiratory problems. Be sure to understand the specific properties of the refrigerant you are using and follow necessary safety measures to prevent hazardous situations. This detector is a hand-held inspection tool for locating leaks while you hold and watch it; it is not a substitute for a listed gas alarm.
