DigiS/E
humidity-temperature probe
PRODUCT DESCRIPTION
DigiS/E probe with the I²C output is designed to measure air temperature and
relative humidity in chemically non-aggressive environments. It is designed
for connection to COMET devices equipped with inputs for Digi/E series probes.
The probe is interchangeable, the calibration constants are saved in the
internal memory of the probe. This probe cannot be connected to devices with
analog inputs, for example a Pt1000 temperature probe.
The probe is suitable for applications with required fast response time.

DIMENSIONS
INSTALLATION
- to devices series Uxxxx and Wx7xx connect the probe directly or use an extension cable SDP001 (see optional accessories)
- do not connect the probe directly to the devices series Wx8xx, always use an SDP001 extension cable with a minimum length of 1 m
- if the probe is connected to the measuring device directly (without an extension cable), do not exceed the operating temperature of the device
The probe does not require any special service or maintenance. We recommend periodic calibration for measurement accuracy validation.

WARNING
- It is not recommended to use the probe for long time in a dusty environment.
- It is not recommended to use the probe for long time under condensation conditions.
- Don´t connect or disconnect the probe cable while device is turned on – incorrect values could be recorded in the memory of the device.
- The probe contains electronic components; it needs to liquidate them according to legal requirements.
