The RDA Paperless Recorder Series is a value priced large format touch screen datalogger that integrates measurement, display, alarm, and datalogging into one slim instrument. The RDA Series is available in both 5' and 7' display models. The instrument is easy to install and requires no external HMI. Depending on the model, the RDA Series can support 2, 4 or up to 6 input channels with either thermocouple or RTD input type with 0.2% FS measuring accuracy. Each channel can have independent input specification, with square-root, multiplication, addition and subtraction. All channels are equipped with digital adjustment and filtering functions.
The RDA Series provides a real time trend records via trend graph or bar graph. History and alarm records can be reviewed in the logger itself with 150MB of internal storage or exported to external USB storage device. The RDA-740 and RDA-760 models have a slim installation depth of 40mm of for use where installation space is limited.

Measurement Accuracy
±0.2%FS ±1 digit / ±0.3%FS ±1 digit (only for Cu50)
±0.2% FS ± 1 digit. Internal cold junction compensation (CJC) will require an additional 1℃ CJC error to be taken into consideration. The stated accuracy for type B thermocouple is only guaranteed between 600~ 1800℃ (+1112 ~ +3272°F).
±0.2%FS ±1 digit / ±0.3%FS ±1 digit (only for Cu50)
±0.2% FS ± 1 digit. Internal cold junction compensation (CJC) will require an additional 1℃ CJC error to be taken into consideration. The stated accuracy for type B thermocouple is only guaranteed between 600~ 1800℃ (+1112 ~ +3272°F).
