H6520 Remote CO2 Concentration, Temperature, Humidity Transmitter, Ethernet Interface, 2 Relay Outputs
H6520
Temperature, humidity, CO2 level transmitter with two output relays. Supports humidity index readings.
The H6520 sensor is designed for online monitoring of air temperature, relative humidity and carbon dioxide and does not contain aggressive substances. Two relay outputs allow control of other equipment.
Highly accurate capacitive polymer sensors ensure excellent long-term calibration stability and ultimate accuracy. Measurements can also be converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific heat.
CO2 measurement is based on a two-source, two-beam process. Long-term stable CO2 measurements are ensured by a proven non-dispersive infrared (NDIR) CO2 measurement cell. A unique patented auto-calibration procedure compensates for IR source aging, ensuring high reliability, long-term stability and eliminating the need for periodic recalibration in the field.
The CO2 concentration can be shown on the display or signaled by colored LEDs.
Measurement data can be processed and analyzed in the following ways:
