Hi there I am hoping to attach a large number of strain gauges toa concrete surface, I need to know the compatibility with these strain gauges and a CR1000 series data logger

Asked by: Rodney99
Rodney, thank you for reaching out to us, the strain gauge will be bonded to the concrete and you will need to complete your bridge first. It appears the CR1000 IS A CAMPBELSCI Data logger, you may have to check with them, on whether it can complete a bridge and log full bridge circuits. If you have more questions please email
