Abstract: A waterproof electrical connector assembly releasably connects an electrical cable to a second cable, or to one or more electrodes or sensors in a housing that has a bore therethrough that accommodates the electrical cable on one end and a fitting on the other end. The fitting holds one or more electrodes/sensors in a bore through the fitting. The fitting is a commercially-available male-threaded polymeric fitting of the type used in High-performance Liquid Chromatography (HPLC) applications. This type of polymeric fitting has a conical, or tapered, ferrule portion at one end that is configured to fit securely into a female-threaded and chamfered bore in the housing so that when the fitting is tightened against the chamfered housing bore it forms a watertight seal which is waterproof to at least 10,000 psi. As the seal is formed, the components contact each other to form an electrical connection, illustratively, a connection from electrode or sensor probes to the cable leading to measuring equipment.

Abstract: A system for monitoring and controlling electrical devices has a local central processor with memory for storing an operating and control systems for controlling analog or digital sensors, instruments, and devices. A web browser interfaces with a communications system to exchange data with the local central processor. External hardware couples to the local central processor via an inter integrated circuit interconnection system. Plural sensors and instruments couple to the local central processor, and are controlled over the internet. Electrical devices include any combination of temperature sensors, potentiometric sensors, oceanographic sensors and instruments, industrial sensors and instruments, voltammetric sensors, light sensors, atmospheric sensors and instruments, water sensors, pH sensors, and amperometric sensors and instruments. Sensor data is stored in a removable data storage arrangement.

Abstract: A system for acquiring environmental data from a plurality of sensors is provided with a microprocessor having a sensor input for receiving data from a sensor, a memory access port for communicating with a memory system, and an output port for issuing data. Plural sensors each produce associated sensor signals responsive to respective characteristics of an environment. The sensor signals are propagated to the sensor input of the microprocessor, and a memory system is coupled to the memory access port of the microprocessor for storing calibration data associated with the plurality of sensors. A communications arrangement is coupled to the output port of the microprocessor.

Abstract: A sensor arrangement has first and second substrates arranged in juxtaposed relation to each other. A working electrode is interposed between the first and second substrates. At least one of the first and second substrates has transaxial scoring for facilitating the snapping off of segments of the first and second substrates to expose a clean portion of the working electrode. A further electrode, which may be a silver deposition, is disposed on the first substrate. A still further electrode, which may be a gold deposition, is disposed on the second substrate. The working electrode is a wire disposed axially in relation to the first and second substrates. The wire is formed of gold, indium, glassy carbon, copper, silver, or the like, and any of these can be used alone or as an amalgam with mercury. The working electrode may be printed or deposited on at least one of the substrates.
