Portable 200%FS Groundwater Data Logger -30~80 Degree
Feature of Groundwater Data Logger
1. High measuring accuracy, resolution and robustness due to the
use of the latest Micro-processing technique.
2. High data security due to the use of a non-volatile memory.
3. Completely record the pressure, temperature and the recording time.
4. Flexibly set the collection interval time with the shortest interval time 1s,
and the longest interval time 255 hours 59 minutes 59 seconds.
5. 5000 recordings could be recorded.
6. Read the pressure and the temperature value via RS485 communication
interface at any time.
7. Back to factory setup offers customer easy to restore factory setup
when make incorrect operations and reduces the maintenance fees.
8.High stable, hardware watch-dog and muti-track software inspection
could reduce the system halted.
Description of Groundwater Data Logger
PL315 Groundwater Data Logger works with an absolute pressure sensor. If the influence of air pressure fluctuations (e.g. at shallow fluid or water depths) is going to be taken into consideration, it is recommended that a second data logger PL315 is placed at the surface, to record the barometric pressure. The correct level is calculated via PC by subtracting the two measured values of the two data loggers.
Sensor, circuit board and battery air assembled into the sealed steel housing, for submersible application. For data read out, PL315 must be got back from the measuring point. The O-ring sealed end cap is then removed to the access to data port.
