The company says there is no catch: all you have to do is purchase two packs of their high quality reagents for every free calibration - and you are probably buying them already
This offer applies to Hach Lange spectrophotometers (DR2000, DR2010, DR2400 and DR2500), will run until 31 July 2007, and is only available to UK mainland customers.
A certificate will be provided for calibrated instruments, thereby validating results for the subsequent 12 months.
UK lab sales manager Matthew Dillon says: "Two reagent packs might only cost around £100, so a free calibration visit will be very attractive to large numbers of UK laboratories.
"We anticipate a massive demand for this offer and customers will be responded to on a first-come, first-served basis.
"Hach spectrophotometers have been market leaders for many years because of their reliability and accuracy, however, a calibration visit will help to ensure that testing remains of the highest quality."
