Maritime Industry
We offer a complete program of maritime DNV approved pressure, temperature, and signal calibrators and pressure generators. Our complete systems include digital pressure gauges, temperature calibrators, hand held pneumatic and hydraulic pumps, and a variety of hoses and fittings to fit your calibration needs. We even offer equipment that only needs to be recalibrated every three years, reducing the overall cost of ownership by 67%.

General Calibration and Maintenance – Pressure gauges, pressure and temperature transmitters, transducers, electronic sensors, valves, regulators, and pressure and temperature switches need to be checked and calibrated periodically. nVision, XP2i, 30 Series, MTC, CTCPTCASC-400

Exhaust Thermometers – Check / adjustment of engine injection systems and their exhaust thermometers. Used optimize fuel consumption, and to fulfill requirements from classification societies. MTC, CTCPTC

Tank Level – Producers store their inventory in holding tanks, and an accurate pressure and temperature measurement of each storage vessel creates a record of their inventory on-hand. The nVision offers an easy and fast way to record accurate pressure measurements and the MTC measures and calibrates temperature. nVision, HPC40, XP2i, MTC

Pump Testing – The nVision monitors inlet and outlet pressures and records from two pressure sensors, up to 15 000 psi, as fast as 10 times per second, to characterize the pump. nVision, HPC40, ASC-400 with APM

Filter Testing – The nVision can measure and record differential pressure at high static pressure directly across a filter. By estimating a filter's relative age and wear in this manner, a customer can save money by only replacing filters when needed. nVision, HPC40

Barometric Pressure Measurement
– Some applications, such as calibrating absolute pressure gauges, will require the reference gauge to read directly in barometric pressure. The nVision and the HPC40 series, with the optional barometric reference will indicate pressure in the absolute scale. You can even toggle between gauge and absolute pressure on the same device. nVision, HPC40, ASC-400 with APM

Relief Valve and Rupture Disc Testing – Pressure safety valves and rupture discs protect pressure vessels and piping systems from excessive internal pressure. Periodic testing and adjustment of this equipment is essential to maintain overall safety. Our equipment catches the maximum pressure at high speeds (up to 10 readings per second) to complete and document the tests. nVision, HPC40XP2i, m1M

Torque/Tensioning/Force – When using hydraulic pressure for tensioning and lifting, it is possible to utilize the special custom engineering unit, and read directly in ft/lbs, N m, or any other customized unit. nVision, XP2i, HPC40, 30 Series

Custody Transfer – When transferring oil or gas to or from a ship, accuracy is of the utmost importance. The high accuracy PKII is the de-facto standard used in gas measurement. The nVision also meets the custody transfer required accuracy of ± 0.025%. In addition to pressure, temperature is also an important factor in precise flow calculations. The RTC-157, with its active dual zone heating technology, together with a reference probe is capable of measuring ± 0.07°F (0.04°C). nVision, PKII, RTC, PTC

Datalogging/Data Recording – Record pressure, temperature, current, and voltage at up to 10 readings per second using the nVision. The battery-optimizing, Ultra Low Power (ULP) mode, allows an entire year of continuous recordings on one set of batteries. nVision, XP2i

Wellhead Testing – Found offshore, wellheads provide the pressure interface for both drilling and production equipment. We provide unmatched accuracy to test and record pressures on the wellhead up to 15 000 psi / 1000 bar. nVision, XP2i

Tubing and Casing Pressure Graphing – To make appropriate adjustments to wells, operators must record a well’s casing and tubing pressure simultaneously. Using our reference recorder, these tests can be completed on the surface, saving both money and time. The nVision can record two pressures simultaneously at up to 10 times per second, and store 500,000 readings. nVision

Chart Recorder Replacement – The nVision is an excellent replacement for aging chart recorders. It offers higher accuracy in a smaller, lighter, and more robust package, while saving data in an electronic format. It has been suggested that one 10 000 psi nVision could replace most chart recorders, since chart recorders rarely have better than 1 psi resolution. nVision, XP2i

Transmitter/Flow Computer Calibration and Validation – Static and differential pressures, along with temperature are commonly measured to calculate flow, using transmitters and flow computers. Calibration and validation is needed to assure their accuracy. The nVision allows a user to complete pressure calibration and validation of a differential transmitter, our temperature calibrators calibrate the temperature component, and our ASC-400 and CSC201 simulate the process to the flow computer. nVision, 30 SeriesTemperature Calibrators

Direct Pressure Measurement – Various places throughout oil & gas facilities will require direct measurement of pressure. This could involve permanently mounting an instrument or completed periodic checks. Our instrumentation provides the flexibility and accuracy to confidently measure pressure. nVision, XP2i, HPC40, 30 Series, ASC-400

Calibrating Tank Sensors – When temperature sensors are mounted in hard to reach locations, and they require calibration at very low temperatures, special care must be taken when choosing a temperature calibrator. A portable The RTC-157 B can be used taken to the hard to reach spot, and can cool down to -45°C. RTC, PTC, ETC

Maintenance of Calibration Standards and Test Equipment - Portable calibrators and test equipment requires periodic checks and calibration. Having local standards on board for calibration of these instruments offers a savings in cost and downtime of instruments. The nVision and HPC40 Series are small, light-weight instruments that have the accuracy required to calibrate pressure in the field or in a lab. The RTC and PTC series are excellent standards for the verification and calibration of handheld thermometers. There is no better pressure standard than a deadweight tester for calibrating pressure instruments and our deadweight testers are designed to be highly accurate but durable. nVision, HPC40, DTI1000APM CPF, RTC, PTC, Deadweight Testers
