Valeport Service & Calibration

Valeport’s Service & Calibration Department has a team of dedicated technicians that can service, repair, test and calibrate any Valeport product.  Our facilities allow calibration of the following sensors, all to NAMAS traceable standards:

  • Conductivity / Salinity
  • Temperature
  • Sound Velocity
  • Pressure
  • Flow
  • Fluxgate Compass

We have invested heavily in calibration equipment to enable us to calibrate your instrument to extremely high levels of accuracy:

  • Temperature controlled laboratory
  • 7 x Temperature baths, stable to <1mK/minute
  • 3 x 700 litre Salinity baths, UV filtered, and stable to <2mK/minute and <0.05psu / day
  • Guildline Autosal, ±0.002psu
  • Isotech microK 400 temperature bridge, accurate to ±0.4mK (±0.0004°C)
  • Laboratory Temperature Standards:
    • Triple Point of Water (TPW) cell, ±20µK (±0.00002°C)
    • Gallium Melting Point (MPG) cell, ±1mK (±0.001°C)
  • 2 x Budenburg Class A deadweight pressure testers, ±0.01%
  • Water purification system, <1ppm total dissolved solids, for Sound Velocity calibration
  • Tri axis magnetic field compass calibration rig, ±0.25°
  • Automated tow tank, up to 1m/s

In addition, our standard procedures and facilities ensure that your instrument is calibrated and serviced to the highest level of detail:

  • All storage, assembly, service and calibration areas are protected against static electricity, minimising risk of pcb damage by handling and storage
  • All pcbs are subjected to temperature testing in our dedicated environmental chamber to highlight any weakness
  • Pressure test vessels up to 100Bar allow all new and serviced instruments to be pressure tested before despatch
  • All calibration equipment is itself recalibrated regularly by the manufacturer as appropriate, but in addition, we carry out frequent checks of all key equipment against secondary standards, ensuring that calibration accuracy can be guaranteed

All equipment returned to us is subject to a service procedure that will:

  • Update any firmware / software to latest version
  • Check all bores and seals for damage and debris
  • Check memory and primary batteries
  • Calibration (if requested)
  • Full System check
  • Pressure test to confirm instrument integrity
