The LAQUAtwin EC-33 is the only pocket meter that directly measures conductivity and total dissolved solids (TDS) in 0.12ml sample. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample.
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)

Follow simple, good testing procedures for accurate and dependable results:
Always ensure the sensor is clean before calibrating. If not, clean thoroughly with water (don’t worry, LAQUAtwin meters are completely waterproof!). Place some standard solution on the sensor and press the calibration button. Once the smiley face appears, indicating that calibration is complete, wash off the standard solution with water and dry with a clean, soft tissue.
LAQUAtwin meters only need a tiny amount of sample - so no beaker is necessary. Fill the sensor with the sample and when the smiley face appears, the measurement is complete.
Clean the sensor thoroughly with water, ready for the next test. When the sensor is nearing the end of its usable lifetime, it can be replaced;
1500 measurements or when calibration cannot be completed. Sensors are sold separately and are easily removed and replaced.
Choose the best method according to your sample, your situation and your needs.
LAQUAtwin sampling sheet.
The sampling sheet allows trace volumes to be analysed. For example, you can even measure the pH of human skin by wiping with a sampling sheet soaked in pure water, and placing it on the sensor. Using the HORIBA sampling sheet, volumes down to 0.05 mL can be tested (except for conductivity measurements).
