1. INTRODUCTION

The Optidew chilled mirror hygrometer is based on the proven, fundamental condensation
temperature dew point principle, giving unmatched long-term drift-free performance.
Michell offers three highly durable sensor options, which are suitable for measuring in a wide
variety of different samples.

1.1. Optidew Series

The Optidew 501 features a compact ABS enclosure with an aluminium base plate and 4
external lugs for easy mounting to a panel or wall. It is available with a 5.7" touch screen
display, or as a "transmitter only" version.
A weatherproof version of the Optidew 501 enclosure is available with a modified connector
panel to improve ingress protection to IP65. Note that the Ethernet and SD card options are
not available in combination with the weatherproof version.
The Optidew 401 is designed to be easy to handle and transport and is ideal for laboratory
or service use. It has a 5.7" touch screen LCD fitted as standard.
