Introduction

Thank you for selecting the Extech RH600 Dew Point Meter. The supplied
RH601 probe measures temperature and relative humidity over a wide range
with high accuracy. The RH600 then calculates other readings based on the
probe measurements. See the full list of readings in Section 11,
Specifications.
On the meter’s home page (Section 6), any two readings can be selected to
display, in addition to the fixed temperature display, for a total of three read-
ings on one page.
The RH600 can perform spot checks in ambient air and in industrial proc-
esses where the probe can be mounted directly into pressurized systems.
The probe adapts rapidly from ambient to process conditions and includes a
purge (purification) feature allowing it to dry quickly from process moisture
and condensation (see Section 4).
RH600 features include:
• Color LCD with adjustable brightness.
• Intuitive user interface with three context-sensitive function buttons.
• High quality industrial design for long-term stability and low maintenance.
• Wide measurement range: -58 to 86℉ (-50 to 30℃).
• High and low alarms with audible and visual alerts.
• Sensor is designed especially for low humidity measurements.
• Selectable probe pressure/molar mass settings to match gas under test.
• Data Logger stores time-stamped readings to internal flash drive.
• Data Hold feature locks readings on the display.
• Data Hold readings can also be saved to the internal flash drive.
• PC interface for downloading stored Data Logger and Data Hold readings.
• Open downloaded data files in PC spreadsheet programs.
• Firmware can be upgraded by the user.
• Programmable auto power off utility.
• The package includes RH600 meter, RH601 probe, USB cable, 3.7 V lith-
ium rechargeable battery, AC power plugs, and user documentation.
