Using standard Enviromon software, the fastest data recording rate is once per minute. However, using software we've developed at Metermaster, that rate can be once per 10 seconds. (Our testing was carried out measuring 12 channels, from a mixture of EL001 and EL037 converters).
Feel free to email me if you'd like to know more.
