The Hanna Instruments HI-977 range is comprised of a comprehensive selection of advanced waterproof portable photometers. Most meters in the range have the ability to measure single testing parameters with a few multi-parameter meters completing the selection. Each photometer is designed with an innovative optical system that offers superior performance in accuracy, repeatability, and the amount of time that it takes to do a measurement. Meters are simple and straightforward to use, with a large LCD display and intuitive interface.

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)
