Fully Calibrated Humidity and Temperature Sensor
The ChipCap series humidity sensor offers a new standard in the field of accurate relative humidity measurement. Based on a capacitive polymer sensing technology, this device offers signal conditioning and temperature compensation for a single SoC (System-on-Chip) solution. The device is very simple to use, fully tested and calibrated for accuracy on delivery—no further calibration is needed.
Product Description
ChipCap can be incorporated into an assembly or finished sensor to meet customer specifications. The measurement is accurate to ± 2% from 20% to 80%RH and ± 3% across the entire humidity range. Long term stability is excellent. The temperature accuracy is ± 1°C from 0°C to +70°C. Dual outputs provide humidity and temperature as 0V to 1V, or 0.5V to 4.5V ratiometric or available with digital output (the ZACwire one-wire interface).

Does your organization do calibration of dew point analyzers? if so, please contact me through the email add mentioned above or you can call me at 813-8382 local 646…… Hoping to hear from you soon.

Does this device offer further calibrations in with the price? For example after a year of use I would expect it would need to be re calibrated.

i think the factory calibration is preset on the chip itself and it does not allow the end user to calibrate the chip.

how can I supply 10 samples?

Can I interface this device to a computer? I would like to develop an application that would monitor temperature and humidity changes and output the results in the display area.
