Choose the model RTR-52 and attach an external probe to extend the temperature range to 311°F. For even higher temperatures, select the model RTR-52Pt and connect any 3-wire RTD (Pt100) and achieve temperatures to 1100°F.  With a 16,000 reading memory bank, you can record up to 666 days at an interval of one hour. You can program these loggers to record at virtually any interval from 1 second to 1 hour.

Using the RTR-57U Handheld unit, you can store up to 256,000 readings on up to 250 data recording sessions before download. The RTR-57U can configure start time, logging intervals, and programmed settings from all of your loggers. Data can be previewed graphically and can operate for up to 100 hours on 2 AAA batteries.

Want more? How about getting an email if your wireless loggers exceed your pre-set temperature or humidity limits?. Add on the RTR-5W Network Hub for downloading and monitoring in real-time. Configure up to 3,800 loggers in up to 60 groups and collect data right onto your network. Send warning emails to up to 5 different address and get your notification right to your PDA phone.

You won’t find a more rugged wireless LCD display datalogger than our RTR series.
