The DataSuite release will include a number of improvements and fixes as well as new features such as the addition of a Gmail-based email account for sending alarm notifications via email and Boomerang reports, and a streamlined first-time software setup mechanism. The Gmail account uses port 465 which will make it easier to send DataSuite emails, compared to the existing default email account which uses port 25, increasingly blocked by ISPs in order to prevent spam mail ...

ers, with no limit on number of onsite installations. DataSuite's unified database allows viewing of PicoLite data together with data from other fourtec products, which may already be used by the end-user. DataSuite is also 21 CFR Part 11 compliant, when packaged together with our well established DatPass Admin software (user license is required). PicoLite's direct USB interface means no extra cables or docking stations are required in order to connect to the PC, and battery life of up to 6 months exceeds most standard application requirements in the disposal logger market. 16,000 sample cyclic memory with sampling rate of once per minute to once every 18 hours is sufficient for long-term logging, and in the event of an alarm a LED alarm indicator is included onboard. The PicoLite's internal temperature sensor, with an accuracy of 0. 5 �C, is shipped pre-calibrated, although two-point and offset calibration is also supported via the DataSuite software. A Declaration of Accuracy certificate is ...
