Product review (3 stars): Is a 19 inch wired remote unit including sensor cable "remote"?
This unit is semi-obsolete by today's technology for its features and overpriced for ordinary desktop use. Regular indoor outdoor thermometers read humidity via wireless remote at less cost.
Yes, it does give you the calculated dew point and does seem to be plenty accurate for home use if it serves your needs.

 The sensor can be "extended for measurements in other locations". Extended means 1.6 feet or 50 cm (Not Meters but 19 inches.) Mine is only 40 cm, 16 inches. There is no clock which would be handy to record data.(See Photo) How remote is that? You could extend it through a wall or into a heat duct or enclosure but what "other locations" are within 19 inches?.
I understand the fixed cable to the sensor is made short to fold inside the LCD body. However, it is a big performance/usefulness trade off.
Also, users have no reference to where the probe is reading and where it is read from. ( How much humidity is being added or removed)

There seems to be no zero reset for Max/Min but needs reprogramming to clear max/min history. The two buttons make adjustment a hassle.
To detach the probe, slid the probe UP and gently lift out toward you..

Pros: If you have an enclosure, duct, etc and need humidity read from outside it is 5 stars.
If you want the dew-point for reference is 5 stars.
If you need to read inside a metal duct where wireless will not work it is 5 stars plus.

Cons: If you can't  mount and pass through an enclosure in 19 inches (Or 16 with my unit) 1 star.
If you want to read the humidity or dew point more than 19 inches from the LCD screen :1 star
If you want to use the base and later remove it, the base will probably break as removed.
The ALARM is so quiet you are likely to fail to hear it.
Setup is clumsy. There is no clock which would be handy to record data.

Wanted:The remote sensor with cable attached to a wireless transmitter (like the outside unit on an outdoor thermometer ) sending its signal to the base unit would be a wonderful thing! This falls far short of what could be.

Note: 17 mm hole or .687 (11/16") hole required to insert sensor  or 5/8" hole if the tab to attach to the LCD is cut off.
