Special Notes: Using a surrogate gas such as Hydrogen Sulfide can result in decreased accuracy. For enhanced accuracy performance, we recommend calibrating the Phosphine H sensor with Phosphine calibration gas. An alternative solution is to perform a read-back measurement with Phosphine calibration gas aftr calibrating with Hydrogen Sulfide. Then decide if performance is good enough for the intended application.


Technical Note: TN-114 – Sensor Specifications and Cross Sensitivities for Phosphine H Replacement Sensor

Disclaimer: Technical Note TN-114 presents specifications, cross sensitivities and calibration information on select Rae Systems by Honeywell sensors. All specifications presented in this Technical Note reflect the performance of standalone sensors. For instrument specifications, please refer to product datasheets and manuals. Actual sensor characteristics may differ when the sensor is installed in different instruments. As sensor performance may change over time, specifications provided are for brand new sensors.
