The GraLab 451 worked in our lab very well and as expected. I thought that the instructions for using it as an intervalometer were a bit complicated and confusing. After trying a few steps in the set-up procedure, it worked. It is used to activate the solenoid that controls the reflux ratio in the head of our laboratory distillation apparatus. Compared to competitive intervalometers, it was a very good price.
