Product Description
Heated Diode Intelligent Refrigerant /Halogen  Sensor Leak Detector (SLD-300)


SLD-300 adopts high accurate replaceable semi-conductor sensor which is very sensitive to the refrigerant. And it could filter noise interference and efficiently detect the leakage through the sophisticated microprocessor-controlled circuit and intelligent software algorithms.

1 Replaceable nano sensor: Stable performance of new materials, higher accuracy and sensitivity.
2 Lengthened (43cm) and flexible metal probe: Ease of use, even in a more complex enviroment.
3 Efficient air pump: Locate the leak point more accurately.
4 Rechargeable lithium battery: Large battery capacity, free charge, reducing the battery pollution to the environment.
5 Blow molding case: Easy to carry, better protect the instrument against harsh working environment.


1 SLD-300 with the air pump
2 Unique shape design
3 Flexible stainless probe
4 It will respond to all halogenated (including Chlorine of Fluorine) refrigerants. This includes, but is not limited to:
CFCs e. G. R12, R11, R500, R503 etc...
HCFCs e. G. R22, R123, , R124, R502 etc...
HFCs e. G. R134a, R404a, R125 etc...
5 Detect most gases that contain Chlorine, Fluorine, and Bromine (halogen gases)
6 Detect cleaning agents used in dry cleaning applications such as per chloroethyl
7 Detect halogen gases in fire-extinguishing system
