SECTION 1 INTRODUCTION

The OMEGA® RH70 Handheld Temperature /Humidity / Dew Point Indicator is a microprocessor-based digital hygrometer / thermometer with built-in date storage and an RS-232-C interface. The RH70-Ac can be operated using a rechargeable Ni-Cad battery.

The RH70/RH70-AC Indicator is used for measuring humidity and temperature in heating, ventilation and air conditioning industries. The RH70)/RH70-AC calculates the dew point and displays in either °C or °F. The RH70/RH70-AC features 2% reading accuracy for humidity and 0.2% reading accuracy for temperature. From the front keyboard, the user can select English or Metric Units, operating mode and data storage controls.

This handheld indicator can store up to 999 lines of data. Each single line of data contains one temperature and one relative humidity reading. The dew point reading can not be saved or transformed (it can only be read on the display).

Figure 1.1 shows the RH70 Indicator.
