DL2e Basic Data Logger The DL2e is a simple to use, low cost field data logger, capable of logging a wide range of sensors. Suitably configured, it is compatible with all Delta-T soil moisture sensors. The DL2e can accept 15 input channels, expandable to 60, and the memory capacity is 64k, upgradable to 128k readings.
DL3000 Data Logger  The DL3000 is an advanced, modular logger with powerful windows-based software. It will accept 24 inputs, expandable to 150, and achieves up to 17 bit resolution. It is ideal for use at the heart of complex logging systems - for example to log soil moisture, sap flow and meteorological data simultaneously.
Our catalogue "Data Loggers, Sensors and Analysis" gives detailed information on the DL2e and the DL3000 Loggers

 

ThetaLog type TLOG/1 and TLOG/2 Versatile soil moisture logging - ideal for ThetaProbes Choice of single or dual channel logger  ThetaLogs are a low cost solution to the problem of logging one or two ThetaProbes or Equitensiometers. They are compact, portable and easy to conceal. ThetaLogs can also solve the problem of logging greater numbers of probes when there is a wide distance between sampling points, making long cable runs impractical.  They are sealed to IP67 and can be left out among growing crops without fear of water or dirt ingress.    Despite its small size, the TLOG has an impressive specification: 7900 readings capacity and logging intervals from 1 minute to 10 days.

 

ThetaMeter type HH1 Provides instantaneous readout of soil moisture     Applications The Hand-held Readout Unit type HH1 connects to any ThetaProbe (fitted with a suitable plug) to provide instantaneous readout of soil moisture. A single HH1 can be used to read a large number of in-situ ThetaProbes by connection to each in turn. The unit can be operated with one hand, for convenience in the field.     Display of readings When used with a ThetaMeter, volumetric water content is displayed. Two typical soil calibrations can be switch selected - for mineral or organic soils. Alternatively, the unconverted millivolt output can be displayed, and in this mode the HH1 can also be used with an Equitensiometer (data has to be manually converted to kPa).
