The Pro Series dataloggers with a push-to-start button are available in two models: Model TR220 for temperature and humidity and Model SR200 for temperature. With the push-to-start button, the user decides when to start logging data, which makes it even easier to eliminate unusable predata during testing, shipping, and other monitoring conditions, the manufacturer states. These loggers feature data storage of 32,512 sample points.
