16.10.3 Choosing a datalogging system
1
The schools’ datalogging market is very competitive; good companies will understand
that customers need to take time in making choices. Schools should expect manufact-
urers to provide full technical details, answers to their queries and an opportunity to
try out a datalogging system and its software before placing an order. Sending a
representative to visit, arranging a short-term loan of equipment or putting potential
purchasers in touch with a nearby school already using a similar system allows teach-
ers to gain valuable hands-on experience before purchasing decisions are taken.

See CLEAPSS leaflet PS56, Datalogging Equipment for Secondary Schools for information on current manufacturers and supp-
liers. To support schools purchasing specific datalogger systems, CLEAPSS will, in the future, publish Datalogger Data Sheets
which will report on the results of CLEAPSS tests on the equipment.
