The ASHE AH-74 is a micro-controller based Relative Humidity Indicator with control outputs, offered in a highly compact, rugged and reliable execution. The instrument has three keys on the front panel, with which the operator can set the parameters and configure the instrument as desired.
The instrument accepts RS485 signal from the RH-cum-Temperature sensor probe as input signal. The instrument AH-74 is factory calibrated, so that it doesn't require calibration at the plant site. The AH-74 provides four control Relay outputs, the set points of which may be configured for either Humidifier or Dehumidifier setting with it's independent Hysterisis value, through the Membrane Keypad on the front panel.
The instrument operates on universal AC power supply (90 to 270 V AC, 50/60 Hz) and is offered in standard ¼ DIN panel-mount execution. The instrument has nonvolatile memory. The RH Indicating Controller Model: AH-74 is an ideal instrument for Humidity measurement and control applications. Other features include it's inherent accuracy and immunity to shocks, dust, ambient temperatures, and humidity.
It is available in field-mounting (weather-proof / explosion-proof executions) and standard panel mounting enclosures. Further, the instrument is manufactured using selected high-grade components which guarantee it's functionality and long operational life. All ASHE range of instruments carry a lifetime warranty for design and workmanship.
