Definition A small autonomous data logger designed to monitor conductivity, temperature and depth. Conductivity (accuracy ± 0.003 mS/cm) is measured using a 3-coil closed loop feedback inductive cell for superior temperature compensation. The thermistor (Themometrics) used to record temperature (accuracy ± 0.002°C) is aged and hermetically sealed in the tip of a shock resistant solid glass rod. Pressure (accuracy 0.05% full scale) sensors use reliable semiconductor technology and 316 stainless steel housing developed for long-term stability in harsh environments.
