• Memory of over 240 000 readings in multiple linear and grid batches
• Grid batches as well as linear batches
• Date and time stamping of measurements
• Plot on the display of the Covermeter a 'map' of the readings in a batch for quick and easy
identification of potential trouble spots in a survey
Upgrading of your Covermeter must be carried out by Elcometer or your local Elcometer supplier.
