GPS 12 channel parallel (This is availalble for U-52G, U-53G and U-54G.)
Note:
*Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20? and the backlight OFF.
*Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements against standard solution.
*Repeatability is measured by the ability to reproduce the results against the standard solution (at 25? normal pressure condition).
Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.
The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.
Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.
|
|
|
|
A typical preventative maintenance service includes the following: Inspection and testing of the unit
Dismantling, cleaning and inspection of the key parts
Correction of minor defects including adjustments if necessary
Reassembly and testing
Take post adjustment / cleaning readings
Supply of calibration certificate
Return of the item to you (back to base services)

What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
Seawater has an average salinity of 35 ppt = 35 parts per thousand (equivalent to 35,000ppm or 3.5%). However the salt level does change depending on rainfall, evaporation, ice thawing or rivers, so the salinity can vary over areas, time or seasons. Camlab can offer two handheld meters which quickly and directly measure salinity up to the high levels required for seawater. [caption id=...
