Chapter 1. Features and Capabilities

1.1 Introduction
The GE Measurement & Control Optica is a multi-purpose chilled-mirror hygrometer, suitable for use in a wide variety
of applications. The Optica can function with any GE Measurement & Control chilled-mirror sensor to provide the
following measurement ranges (depending on the sensor selected):
•
dew/frost point from –80°C to +85°C (–112°F to +185°F)
•
relative humidity from 0.002% to 100%
•
moisture content from 500 ppb
•
temperature from -100° to +100°C (-212°F to +212°F)
The Optica also measures and displays gas pressure using a GE Sensing PT-30A or PT-300A pressure sensor, or a user-
supplied 4–20 mA or 0–5 VDC pressure sensor.
Note: If the pressure is known to be constant, a fixed pressure can be programmed, eliminating the need for a
pressure sensor.
Using the Optica, you can simultaneously measure and display dew point, temperature and pressure, with a wide
variety of units of measure. The Optica is Ethernet-ready, so you can access the unit using the Internet for remote
monitoring applications. You can use the data logging function to record and upload weeks of data.
