DKRF670 High-Precision Humidity/Temp. Transmitter
The DKRF670 relative humidity & temperature transmitters were specifically developed for industrial applications. Their measurement range is 0...100% for RH and -40...+120°C at a measurement accuracy of +/-1.8%RH and 0.1°C.
Product Features
- Robust and non-corroding transmitter housing with IP65 rating
- Wide temperature range: -40...+120°C
- Sensor cable length up to 100m
- Additional temperature probe optionally available (e. g. for surface or medium temperature)
- Calculated values include: dew point, absolute humidity, mixing ratio, wet-bulb temperature
- 3 analogue outputs, freely programmable
- Optional LCD for 3 live readings
- USB port for configuration
- Digital interface for terminal controlled data download (USB by default, RS485 or RS232 optional)
The DKRF670 relative humidity and temperature transmitter series proves its strengths especially in industrial applications. Among these are drying processes in the food industry (chips, coffee, spices), climate control in paint shops, as well as HVAC in warehouses and clean rooms (e. g. in the pharmaceutical industry). The DKRF670 is the ideal choice whenever deviating levels of relative humidity can harm your products or hinder your processes. Prevent production downtimes and save money with accurate and reliable monitoring. The transmitters have an excellent long-term stability better than +/-0.5% RH per year (in normal, clean air) which ensures the quality of your measurement results for many years while at the same time it prevents you from having to perform costly recalibrations or replacing parts due to increasing measuring inaccuracy.
Simultaneously measure relative humidity and temperature with one device. An otpional third probe can be equipped for an additional temperature reading, e. g. surface temperature for condensation detection.
Even in dust-laden environments the robust probe is always well protected thanks to a built-in stainless steel sinter filter.
Transmit up to three measured (or calculated) variables to your system control through the analogue outputs or choose the digital interface to be able to download all available readings simultaneously.
Finding the Right Model for Your Application
The DKRF671 has a compact design and comes with its probe directly attached to the transmitter housing. It is best suited for warehouses, clean rooms and production areas.
If you're looking for a transmitter with which to perform measurements in hard to reach spots and confined spaces, the DKRF673 will prove its strengths with its small yet robust probe and cable lengths of up to 100 metres allowing you to install the transmitter in another room or area of your facility. Employing this solution also spares your employees the need to spot-check in these unfavourable locations with hand-held meters.
Should you expect occasional condensation, e. g. in cold warehouses or climate cabinets, we recommend the DKRF676 which has a sensor heating and an additional temperature probe for high-humidity applications.

Accuracy Through Reliable Calibration
We offer optional DAkkS traceable calibration certificates with 3 actual values for relative humidity and 1 temperature reference point at 25°C.
Alternatively, we can provide a certificate with more or with other reference points, and als a DAkkS certificate. Don't hesitate to contact us today!
We offer calibration services in our own laboratory, on-site calibration and replacement probes - you decide what best suits your needs.
Checking or recalibrating your sensors on-site is made easy with our small Humidity Checks
which are independent of orientation and can be ordered with a variety of saturated salt solutions.
