Solar power meter calibration

OTC have commissioned their new solar simulator and are now able to offer traceable calibration of solar power meters. By using a solar simulator rather than a tungsten or other traditional artificial white light source OTC will be able to calibrate a wide range of solar meters without needing to wait for the British weather to produce a clear sunny day!

Bad light stops play?

OTC is proud to have been chosen by the International Cricket Council (ICC) to supply calibrated light meters to their umpires for test cricket.

Bad light stops play may be one of the more controversial calls on the cricket pitch, but at least arguments over when to start play again should be reduced. Each umpire should now have access to a meter which can be used to measure the light level considered ‘bad’ and then determine later whether the level has improved to allow play to resume.

With meters also purchased by six major national cricket boards (and counting!), please join us in enjoying the clouds as well as the sunshine.

Turnaround Statistics

Since 2008, OTC has a key target of ensuring all in-house calibrations are completed within 5 working days. Over the last 3 years, we have carried out cross-discipline training to improve our job flexibility so that all calibrations can be carried out by at least two technicians.

Although we have a little way still to go, operations director Kenny Dove has been keeping score and while our calibration turnround of 93.4% during 2008 was good, our changes resulted in an impressive improvement across 2009 to 98.8% and 99.0% for last year.

Kenny says: "We have been delighted with our improving turnround statistics over the last few years and these statistics highlight the dedication and commitment of our team. We know that downtime can be costly and OTC will continue to find ways to improve our calibration service to our customers."

Megatron Logo

After many years of providing photometric test equipment and service to the lighting and allied industries, Megatron closed down their operations in March 2010 and OTC has continued to provide UKAS accredited calibration of their professional light meters. This has been very successful with over 80% of Megatron calibration customers now using our service.

We also continue to carry out simple repairs but if a Megatron meter cannot be fixed, OTC has a range of suitable replacement meters, supplied complete with half-price calibration.

Details of our light meters range can be found here.
