Chapter 1. Features and capabilities

1.1 Introduction

The

dew.IQ

is a single-channel hygrometer that measures

moisture content in gases. It is suitable for a wide range of

process conditions in applications that require real-time

moisture measurement.
The

dew.IQ

accepts any calibration range provided with

Panametrics probes (see Chapter 7, Specifications for more

information). It comes equipped with two high/low alarm

relays, one fault alarm relay, and a single analog output . It

also has on-board data logging capability using a micro SD

card.

1.2 Electronics

You can program the meter using the keys on the front panel

(see Figure 1 below). The

dew.IQ

universal power supply

accepts voltages from 100 to 240 VAC, or you may order the

24 VDC configuration.
