Data Logger DL18 & DL18-BLE

Product catalog summary

Technical Specifications Summary for Data Logger DL18 & DL18-BLE

Memory: The data logger can store up to 1,900,000 readings. With four dendrometers connected and data collected every 30 minutes, it can store data for approximately 7,900 days.

Resolution: The resolution varies by dendrometer type: 0.2 µm for types DR1, DR3, DD-L1, DD-S1, DD-S2, DRO, DRW, DDW, DC1, DV; 0.3 µm for types DC2, DF1; 0.5 µm for types DC3, DD-L2, DR2, DF2; and 1.0 µm for types DC4, DD-L3, DF3.

Accuracy: The accuracy is ±0.1% of the reading.

Interface: The DL18 model uses a USB interface to connect to a PC, while the DL18 BLE model uses Bluetooth Low Energy to connect to Windows-PC, smartphones, or tablets.

Channels: There are 4 channels available for connecting up to 4 dendrometers.

Logging Interval: The logging interval is user-selectable, ranging from 1 second to 18 hours.

Battery Life: The typical battery life is 1 year with a logging rate of 1 minute and a sampling interval of 15 seconds or greater. It uses 2 AAA batteries, which are user-replaceable.

Environment: The logger operates in temperatures ranging from -20° to 70°C (-4 to 158°F) and 0 to 95% relative humidity (non-condensing).

Compatible Sensor Types: The logger is compatible with various sensor types, including soil moisture (EM 35), leaf temperature (LAT-B2), surface/tissue/soil temperature (T-Surface/-Tissue/-Soil), air temperature/humidity (T/RH-Sens), and light (PAR: EM 20, Pyranometer: EM 25).
