3rd Generation SediMeters Mechanical Cleaner Vibrator UV LED
SediMeter SM3A SM3A Our base model SediMeter. Reports the through-the-bottom turbidity profile with 5 mm resolution over 35 cm, using a combination of straight and oblique backscatter. Also reports backscatter turbidity 11 cm higher up, temperature, and the estimated bed level with 0.01 mm resolution. It can be used both for stand-alone logging, and for real-time monitoring. This is the workhorse, and perfectly adecuate for many applications where no cleaner is necessary. - - -
SediMeter SM3B SediMeter SM3B This SediMeter has a mechanical sensor cleaner that wipes the sensor at user-set intervals. To power the cleaner it has a much larger battery than the SM3A. Y - -
SediMeter SM3C This is identical to SM3A, except that it also has a vibrator for shaking off particles and bubbles. - Y -
4th Generation SediMeters All have ISO and EPA-style turbidimeters, and accelerometer
SediMeter SM4A To be released in Sept 2017 This is the base model of the 4th generation. It is similar to the SM3A in dimensions and battery size, but it also sports an ISO-style and EPA-style (U.S.) turbidimeter, an accelerometer, UV LEDs to discourage growth on the turbidimeter window, and a vibrator for shaking off particles and bubbles. The sensor diameter is 15 mm. - Y Y
SediMeter SM4B To be released in Sept 2017 This model has the same sensors and UV LEDs as model SM4A, but instead of the vibrator it has the same mechanical cleaner and battery as model SM3B. The sensor diameter is 15 mm over the OBS array, and 20 mm over the turbidimeters. Y - Y
SediMeter SM4C To be released in Sept 2017 This is identical to SM4A, except that it has the larger battery of SM3B and SM4B, and a sensor diameter of 20 mm instead of 15 mm (which also means that it is much stronger). - Y Y
Telemetry By license-free radio, or cellular phone
SediLink SediLink radio modem SediLink mounted on a buoy The SediLink radio modem links one or more SediMeters to a PC running the SediMeter software, using a low-power XBee® radio. The maximal range depends on country-specific regulations on frequency and effect.
Also available with buoy. Consider this option when you cannot run a cable, or the distance is too large. XBee radios can also forward the message from SediLink to SediLink, thus extending the total range of the measurement system.
For customers in the U.S. we can also offer a cellular phone option. Contact us for a quote.
