Connects sensors with pulse outputs to data loggers with smart-sensor inputs. Compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch type of normally open. See how the pulse recorder works.
- Plug-n-play adapter for pulse output sensors
- Automatically recognized by H21, H22, U30, and ZW data loggers
- Compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second)
