%RH Transmitter Model 650 from EdgeTech

Accurate Humidity measurements are becoming increasingly important, especially in regarding energy savings, indoor air quality and environmental protection.

Highly accurate and reliable measurement and control of humidity and temperature is required for many industrial processes. The integrated microprocessor accepts the linearisation and compensation for humidity over the whole range from -40 to +180° C. This guarantees highest accuracy of up to ± 1% RH. In addition to relative humidity and temperature, dew point can be also be calculated. Up to 32 transducers can be analyzed on a PC. The optional LED display is easy to read.

The Model 650 incorporates a ±1% maintenance free humidity probe ideal for checking humidity measurements for validation of critical environments. It's rugged, compact and protected by a water proof plastic housing. The Humidity measuring angle is 0-100%RH. The accuracy of this probe has been tested and proven time and again in worldwide laboratory tests. The probe is equipped with a patented %RH sensor.

Benefits:
• Highest precision of ±1% RH (10-90%; ± 2% remaining range)
• Mollier diagram integrates C°, %RH, td, g/m³, g/kg.
• Housing with LED display
• 2 wire technology, 4 to 20mA for signal and power
• Variable cable lengths up to 10m
• Variable scaling of outputs signals possible
• Parallel analysis of up to 32 transducers via PC (RS485)

Description:
The precision temperature/humidity measuring instrument includes the basic parameters - temperature, dew point and %RH.
• Rapid Measurement with accurate temperature probes. The measuring instrument extrapolates the final value.
• Highest precision due to system calibration (measuring instrument + probe). Calibration data is saved in the probe.
• Calculates all of the physical humidity parameters in the Mollier diagram:

• Guaranteed long-term stability < 1% over 2 years
• Highest accuracy up to ±1%
