    Chart Recorders

    I have a blood fridge that has built in Chart Recorder which has developed a fault / plus another one which I am having real difficulty sourcing the chart paper - so was wondering if anyone has taken the leap and determined that they are obsolete attachments to appliances?
    At present we get annual mapping (UKAS standard check on the appliance chamber) and maintenance checks performed, plus have a separate temperature monitoring system which also is UKAS Calibrated and alarms when temperatures are out of their specified ranges. Whilst the chart recorders are checked / reviewed retrospectively at end of week to look for any peaks ... but sometimes find that it's stopped recording half way through the week ??
    Any feedback / thoughts on this matter will be gratefully appreciated - thanks

    Hi Marks8,
    We implemented wireless monitoring around 2012, and stopped using the chart recorders in 2013- with no significant issues. Though the recorders are still attached, they are no longer calibrated and there is a sign across each one to state that temperature monitoring is via XX system.
    However, have a think about what your contingency plan is if your monitoring system goes down ( we have sufficient calibrated data loggers we can place in our fridges).

    Thanks for the reply Rashmi - yes we've had a wireless monitoring system for a while as well and have been using the chart recorders as simply belt and braces ... it may work out cheaper in the long run to invest in some data loggers and just get then calibrated annually (food for thought)

    Quick follow-up question , how often do you get your data loggers recalibrated to UKAS standard ?

    Annually - and we send to be calibrated in two separate batches to ensure sufficient remaining in-house when the first batch is out.
    We keep quite a few loggers as these also go into our HEMS boxes.
