Description
The Honeywell Zellweger 04230-A-1001 (Type SHC 1) is a dedicated calibration tool designed for the precision maintenance and verification of Honeywell/Zellweger gas detection transmitters. This portable calibrator is essential for field technicians to perform routine “zero” and “span” adjustments, ensuring that gas detectors remain accurate and compliant with industrial safety regulations. It serves as a vital bridge between the field transmitter and the calibration gas source.

🚀 Integration and Application
The SHC 1 is an indispensable tool for maintenance teams managing gas detection fleets. It is typically used in conjunction with:
- Calibration Gas Cylinders – Certified test gases (e.g., LEL, H2S, CO) required for span verification.
- Flow Adapters (Calibration Cups) – Used to seal the gas over the sensor head during calibration.
- Field Transmitters – Interfaces directly with models like the Searchpoint or XCD to display real-time sensor output during the calibration process.
- Calibration Logs – Used to document “As Found” and “As Left” data for safety compliance audit trails.
⚠️ Calibration and Maintenance Note
Using the 04230-A-1001 requires strict adherence to calibration protocols to maintain sensor life and accuracy:
- Environmental Stability: Always allow the gas detector to reach ambient temperature before starting calibration, as temperature fluctuations can cause significant span errors.
- Gas Flow Rate: Ensure the regulator on your calibration gas cylinder is set to the flow rate specified in the sensor’s manual (typically 0.5 to 1.0 liters per minute).
- Sensor Aging: If you find that the sensor requires frequent adjustments or if it cannot reach the target span value, this is a clear indicator that the sensor element is at the end of its operational life and requires replacement.
