GD-K71D-O3-10 GD-K71D Smart Transmitter, Ozone (O3), 0 - 1 ppm by RKI Instruments
The GD-K71D is a complete sample drawing gas monitor, including digital readout and alarm relays. A new gas sensor technology using an intelligent sensor for remote location calibration and setup is used. The new GD-K71D sensors are designed to provide a longer time period between calibrations. Calibration intervals have been extended to12 months of on-line service which equates to reduced maintenance cost. In addition, the sensors can be calibrated away from the gas detector installation, for example in a service area or off site. This eliminates the inconvenience of having calibration gases in the fab or monitoring location. GD-K71D easily connects to an existing PLC system and is ideal for applications needing a local readout or where a relay control is needed. The automatic zero correction software provides excellent long term stability and minimizes false alarms due to zero drift.
Features:
- LED digital display
- Sensor information and calibration is stored within sensor memory
- Several data transmission options available
- Zero suppression and correction
- Housing design for narrow wall mounting locations
- Self-diagnostic functions by microprocessor
- Electrochemical sensors for most semiconductor gases
- Built-in sampling pump
- Easy replacement of pump and sensor
- Two alarm levels with relays, plus trouble alarm
- 24VDC operation
- Optional NEMA 4X housing available
Applications:
- Semiconductor
- Chemical Processing
- Laboratory
- Manufacturing
- HVAC
