RH101 Datasheet, PDF (2/8 Pages) HY ELECTRONIC CORP. – SURFACE MOUNT GLASS PASSIVATED BARRIER RECTIFIERS

Introduction
Congratulations on your purchase of the Extech Hygro-Thermometer plus InfraRed
Thermometer. This device measures relative humidity, air temperature (with probe), and
surface temperature (with the InfraRed function). The large, easy-to-read backlit LCD
includes primary and secondary displays plus numerous status indicators. The InfraRed
feature includes a laser pointer for convenient targeting. Careful use of this meter will
provide years of reliable service.

Safety
• Use extreme caution when the laser pointer beam is on
• Do not point the beam toward anyone's eye or allow the beam
to strike the eye from a reflective surface
• Do not use the laser near explosive gases or in other
potentially explosive areas
