  • Vertical & Horizontal water sampling in shallow or deep waters (ideal for thermocline, at other stratification levels or above sediments)
  • Transparent (allows view of bottle content)
  • Designed for trace metal sampling (also used for organic sampling)


  • Features real-time monitoring of water column temperature stratification, meteorological parameters and water quality parameters
  • Complete monitoring buoy for long-term water quality monitoring and management
  • Able to transmit data via GSM cell phone or either methods to a used specified destination
  • Measurements are typically collected once per minute, but can be collected as often as once every few seconds.

PME miniDO2T

  • Collects temperature and dissolved oxygen measurements and stores them to an internal 2GB SD card
  • Measures lifetime-based luminescence quenching or fluorescence of a thin membrane
  • Collect measurements of dissolved oxygen with an accuracy of +/-5% and temperature to +/- 0.1 degrees 
  • Self contained and able to function within a variety of liquid environment

PME T-Chain

  • Temperature string designed to collect temperature, dissolved oxygen and pressure measurements as rapidly as once per second along a customer specified node location cable
  • Unique due to its very high temperature accuracy and rapid response to temperature variations
  • Used as water quality monitoring and lake management device that collects water column temperature, dissolved oxygen, PAR, pressure, chlorophyll a, and conductivity measurements.
  • Currently used to monitor lake and reservoir thermocline and stratification, detect dissolved oxygen fluctuations, observe internal waves, collect data under ice, discover plumes, observe upwelling and eddies, record lake turnover and more.

Eureka Manta 2 Multiparameter Sonde

  • Comes standard with 6 sensors in less than 2" diameter housing
