INTRODUCTION

FEATURES

The RLD15B features a solid electrolyte semicon­ductor sensor that is designed to detect the more
current and difficult HFC refrigerants such as
R134a, R1234yf, R410A, R404A, R407C, in addition to
all HCFC (R22) and CFC (R12) refrigerants includ­ing SNAP approved hydrocarbon blends.
