A PRECISION PYRANOMETER, USED TO MEASURE TOTAL SOLAR RADIATION. THE PYRANOMETER IS UTILISED BY WEATHER STATION MANUFACTURERS AND EASILY INTEGRATES WITH DATA LOGGERS. IT INCORPORATES A CALIBRATED SILICON-CELL PHOTO DIODE SENSOR, ACCURATE TO +/- 5% UNDER CLEAR SKY CONDITIONS, WITH EXCELLENT COSINE RESPONSE. IT HAS A SELF CLEANING DOME SHAPED HEAD AND IS POTTED SOLID TO WITHSTAND EXTREME HUMID CONDITIONS, AND REDUCE THERMAL BASED ACCURACY FLUCTUATIONS. DIMENSIONS: 2.40 CM DIAMETER, 2.75 CM HIGH. MASS: 90 G (WITH 5 M OF LEAD WIRE).

A GEOPHYSICAL INSTRUMENT. A MARINE MAGNETOMETER SPECIFICALLY DESIGNED FOR MEASURING THE EARTHS MAGNETIC FIELD. USED IN PROFESSIONAL SURVEYS IN SHALLOW OR DEEP WATER. THE SYSTEM IS PARTICULARY WELL SUITED FOR THE DETECTION AND MAPPING OF ALL SIZES OF FERROUS OBJECTS, WHICH INCLUDES ANCHORS, CHAINS, CABLE, PIPELINES, BALLAST STONE AND OTHER SCATTERED SHIPWRECK DEBRIS. HAS A DEPTH RATING OF 4000 PSI. POWER MAY BE SUPLIED FROM A 24 TO 30 VDC BATTERY SUPPLY OR 110/220 VAC POWER SUPPLY.

THE PRODUCT IS USED FOR SEISMIC RECORDING MARINE APARATUS. THEY ARE USED AS A MEANS OF IMAGING STRUCTURES BELOW THE EARTHS CRUST BY RECORDING THE ACOUSTIC SIGNALS AND FROM VIBRATIONS IN THE EARTH THAT ARE DERIVED EITHER FROM MAN MADE SHOCK WAVES OR FROM NATURALLY OCCURING SEISMIC WAVES. THE SYSTEM CONSISTS ON A/D CONVERTER CANISTERS, HYDROPHONE SECTIONS, STRETCH AND VIBRATION ISOLATION SECTIONS, A TOW CABLE, CONTROLLER AND STREAMER POWER SUPPLY UNIT.

A LAND GRAVITY METER. A GEOPHYSICAL INSTRUMENT THAT MEASURES THE GRAVITATIONAL FEILD ON LAND. THE GRAVITY METER IS EQUIPPED WITH A RADIO FREQUENCY REMOTE START TRANSMITTER. POWERED BY RECHARGEABLE LITHIUM-ION BATTERIES. SENSOR TYPE IS FUSED QUARTZ USING ELECTROSTATIC NULLING. DIMENSIONS 30CM X 22CM X 21CM. WEIGHT 8KG.

A PORTABLE , ELECTRONIC GEOPHYSICAL INSTRUMENT. A SEISMIC ENERGY SOURCE FOR USE IN A MARINE ENVIRONMENT. THE FUNCTION OF THE DEVICE IS TO CREATE A SEISMIC SHOCK WAVE IN THE MARINE ENVIRONMENT WHICH WILL TRAVEL THROUGH THE WATER AND ONWARD THROUGH THE UNDERLYING GEOLOGY TO REFLECT AND REFRACT OFF GEOLOGICAL STRATA. THE PRODUCT IS PREDOMINANTLY USED AS A TOOL FOR MAPPING RELATIVELY SHALLOW STRUCTURES WITHIN THE EARTHS CRUST AND IS USED FOR CIVIL ENGINEERING APPLICATIONS FOR MINERAL EXPLORATION AND FOR SHALLOW GAS HAZZARD DETECTION. THE SYSTEM CONSISTS OF THE SOURCE VEHICLE , THE SEISMIC TRANSCEIVER, POWER SUPPLY AND HYDROPHONE STREAMER CABLE.
