Our resistivity Meter

The CIA regrets that the very successful TR/CIA Resistivity Meter is no longer in production, due to the new EU regulations concerning soldering equipment. Contact Kevan Fadden for the latest situation, and to be put on the waiting list should the problems be overcome. These pages provide details of the meter.

The increasing use of the Resistivity meter in recent years has revolutionised archaeology, and they have won an unexpected place in the popular imagination by the Time Team’s use of the ‘Geophyzz’. Yet the price of these machines was often beyond the range of the average archaeological society. Simple machines, without any means of recording the data except by writing down each reading – tended to come out at around between £1000 – £2000. A ‘proper’ one with a data logger whereby the readings could be recorded automatically and then read back into a computer – usually cost around £5,000.

We felt we could do better. Fortunately, Bob Randall, an amateur archaeologist and professional electronics engineer came to our help. He designed and produced an entirely new machine for around £1,000. The first 25 have already been delivered to 25 lucky members of the CIA and they are now in use round the country and are winning increased applause for their simplicity, ruggedness and effectiveness. They will take up to 15,000 readings at a time, which can then be down-loaded into any standard computer programme of the ‘Photoshop’ type and the results then appear on screen or can be printed out.
