Oldham Replacement Hydrogen (H₂) Sensor for iTrans® & iTrans2® – Mfg. #77024446
The Oldham 77024446 Replacement Hydrogen (H₂) Sensor is a genuine OEM replacement sensor developed specifically for the Oldham iTrans® and iTrans2® fixed gas detection platforms. Designed to detect hydrogen (H₂) concentrations in parts per million (ppm), this electrochemical sensor restores the performance of your gas detection system while helping maintain workplace safety and regulatory compliance.
Over time, gas sensors naturally lose sensitivity due to age, environmental conditions, and continuous exposure to target gases. Replacing worn or failed sensors with genuine Oldham replacement components helps ensure accurate gas measurements, dependable alarm activation, and successful calibration.
The 77024446 installs directly into compatible iTrans and iTrans2 transmitters, making it an ideal solution for preventive maintenance programs or repairs following sensor failure. Using OEM replacement sensors also helps preserve system performance and minimizes compatibility concerns commonly associated with non-genuine replacement parts.

Why Choose the Oldham 77024446 Hydrogen Sensor?
Hydrogen is widely used throughout manufacturing, semiconductor production, battery facilities, chemical processing, power generation, and research laboratories. Because hydrogen is colorless, odorless, and highly flammable, continuous monitoring is critical for protecting personnel and equipment.
Replacing an aging hydrogen sensor before performance degrades helps minimize nuisance alarms, calibration failures, and inaccurate gas readings. The genuine Oldham 77024446 is engineered specifically for the iTrans and iTrans2 platforms, ensuring dependable operation and maintaining the performance expected from your fixed gas detection system.
Using OEM replacement sensors also reduces compatibility concerns and helps maximize system reliability throughout the sensor's service life.
