  • Antifouling Screen: Weight 22g Length 50mm Dia 25mm. Material Phosphor Bronze (98% copper) Note. In “Log time” mode the dipperLog NANO increases the readings from 1 second by an additional 1 second for 255 readings. The final reading interval is 4 min and 14 secs and the logger then stops logging. This mode logs for a total of 9 hours before stopping.
