[Bruce comments: below follows a compendium of info from the sowacs
archives on the Aquaterr.
The contact info for Spectrum Technlogies Inc. is available on the page:
http://www.sowacs.com/suppliers/index.html#spectrum
although this sensor is not listed in their online catalog.
I still cannot find a photo of the Aquaterr 200.

[The most useful discussion in the sowacs archives is at:
www.sowacs.com\archives\99-08\msg00010.html
but one of the comparison papers listed on sowacs includes the Aquaterr:

Bruce]
Another reference to this on sowacs is
http://www.sowacs.com/archives/99-08/msg00013.html
which provides a link to the site http://www.specmeters.com/ but there is
no mention of the Aquaterr there now. (I have copied this to specmeters
but had no response from them).
On the sowacs Comparisons page, there is a link to an article that includes
a comparison of the Aquaterr against others, but doesn't name a supplier:
http://www.greenindustry.com/ij/1999/0499/499soil.asp
A "quick" Google search (two hours later) revealed many interesting
webpages that reported the use of the sensor, and often comparison with
other types (these have all bee added to the comparisons page). I did see a
few resellers listed, but could not find the manufacturers website as such
apart from this address
(Aquaterr Inc, 3459 Edison Way, Fremont, CA 94538) (found on
http://www.abs.sdstate.edu/hort/ho413/H413L12.html)
Looking through the sowacs email group archives I came across only the
following two posts and one article which I have reproduced here:
http://www.sowacs.com\feature\Irrigation Journal-Apr 99 - Soil Moisture
Instruments.htm
"The Aquaterr Moisture Meter is a steel rod containing electrodes at its
tip and is pushed into the soil to the desired depth. A qualitative
description of soil moisture content is obtained by comparing the
instrument reading with a color-coded chart. This instrument responded
reasonably well to changes in soil moisture content except at one site
where its response was poor. It is very inexpensive and easy to operate."
http://www.sowacs.com\archives\99-08\msg00016.html
We used the model 100 analog version several years ago. I was impressed
with it's ease of use, durability and relative accuracy when compared with
the tried and true "feel" method of estimating soil moisture. It's best
suited for farmer use. Tad Wenes of Aquaterr (USA 1-800-284-1024) was a
lot of help to us. It's been three years sense I've talked with him.

Our company sold a few of these many years ago, when the Aquaterr was under
different ownership. One NZ customer thought it was great, but did some
mods to the circuitry to get it calibrated correctly. The principle of
operation is capacitive.
We found the cost was about the the same, maybe a bit more from memory as
Soilmoistures Quickdraw, which is a very good portable tensiometer.
Usability was about the same, without all the calibration issues, batteries
etc.
Just an opinion.
