As I have never used their loggers, I had a short training course last week at Delta-T and, I must say that I was impressed by their loggers. They seem robust and easy to set up with good software. They are powered by both internal and external batteries. More details on the website http://www.delta-t.co.uk and prices from martin.evans@delta-t.co.uk.

Gypsum blocks are usually read manually although I'm aware of a couple options for logging that include radio transmission to a receiver/logging device (MEA, Adcon). These are quite expensive. I'm looking for a stand alone gypsum block logger that can be left in the field to record "continuous" data from a small array of blocks (say 6), which can then be downloaded. It must be inexpensive. Some components would be- AC power source; Actuating electronics for periodic measurements; Resistance or current meter; Logger; Multiple input ports/channels (nominally 6); Download port; Supporting software including calibration of resistance to tension for appropriate porous media devices would be desirable. Do you know of anything that would satisfy these requirements. Regards, Mike Schulz Serve-Ag Pty.
