A perfect marriage of proven pressure sensor technology and advanced microprocessor-based electronics, our DCX family of water level loggers is ideal for shallow or deep well water logging applications. Combining a water level logger with a temperature data logger, these instruments are designed and constructed to provide years of trouble-free service under the most demanding conditions. Data capture is accomplished by periodic data transfer to a laptop or Pocket PC (Windows CE) or, for remote installations, by GSM modem technology. Keller's DCX family of submersible water level and temperature data loggers are up to the task.
