AML Oceanographic (AML) has partnered with OSIL to offer Xchange sensor recalibration services at OSIL’s facilities in the U.K. With a European recalibration center, field-swappable sensor-heads become even more convenient for European users of oceanographic instrumentation. OSIL is expected to begin accepting Xchange sensor-heads for recalibration by March 1, 2014. AML’s Xchange line is a series of field-swappable sensor-heads. Each sensor-head contains its own embedded calibration, allowing the sensor to work with any AML instrument. Field-swappable sensors also streamline recalibration: instead of sending the entire instrument back to a calibration center, a recalibrated sensor-head can be delivered to the instrument in the field.
Instrument downtime is dramatically reduced. Established in 1974, AML Oceanographic (www.amloceanographic.com) designs and manufactures innovative instruments for the ocean sensing market. AML is headquartered in Victoria, on Canada’s Pacific coast. OSIL (www.osil.co.uk) provides marine instruments and systems for environmental measurement and monitoring. OSIL also provides a range of high precision calibration standards for measuring salinity including IAPSO Standard Seawater, Low Nutrient Seawater and Iodate Standards. OSIL is located in Havant, near Portsmouth.
Amron International has developed the Model 8330i, an integrated air control, depth monitoring (pneumo) and optional communication unit for up to 3 surface-supplied divers. Designed to meet the IMCA guideline that “no other diver is deprived of breathing gas if another diver’s umbilical is cut or ruptured,” the Model 8330i features independent high- and low-pressure air supplies for all 3 divers. The inclusion of crossover valves between the 3 air supplies, each of which has been designed by Amron to safely accommodate up to 3 divers by itself at one time, provides dual backups in the event of an emergency affecting 1 or 2 divers, such as air supply contamination or failure.
In addition to the air control section, the Model 8330i features a pneumo panel with 6-in. depth gauges capable of registering depths up to 250FSW/76MSW and an optional panel-mounted version of Amron’s Amcom III radio module for diver communication. The unit is entirely self-contained and is housed in a durable, pressure-fused fiberglass case.
