TELEDYNE-Trace Moisture Analyzer​​ Model 8800B

The TELEDYNE 8800B Trace Moisture Analyzer is an advanced moisture measurement solution utilizing field-proven aluminum oxide (Al₂O₃) sensing technology to deliver precise trace moisture detection for continuous monitoring or spot checks. Known for its exceptional sensitivity and reliability, the TELEDYNE 8800B Trace Moisture Analyzer is trusted across industries such as petrochemical processing, natural gas production, and semiconductor manufacturing where moisture control is critical.

At the heart of this analyzer lies TELEDYNE’s proprietary Hyper Thin Film (HTF) sensor technology, which offers significant performance improvements over conventional Al₂O₃ sensors. These include enhanced sensitivity, superior long-term stability, and remarkably fast response times. The HTF design introduces a sharply defined barrier layer between the aluminum core and oxide layer, reducing capacitance drift and minimizing metal migration, one of the main causes of sensor aging.

Another major innovation is the ultra-thin oxide layer of the HTF sensor. Because capacitance is inversely proportional to the distance between the sensor’s electrodes, this thinner layer generates stronger signals, allowing the device to detect even the slightest changes in moisture content. The design also accelerates water molecule diffusion, enabling rapid wet-to-dry and dry-to-wet transitions, which is crucial in dynamic process environments.

Pore geometry plays a key role in the device’s accuracy and longevity. Unlike traditional hygroscopic structures that degrade over time, the HTF sensor uses a stable pore design that maintains dielectric consistency. This means lower drift rates, less frequent recalibration, and more consistent readings over years of operation.

For flexibility, the analyzer offers a TELEDYNE 8800B Trace Moisture Analyzer. Users can view moisture content at sensor pressure or adjust for line pressure, displaying dew point in °C/°F or converting to ppm values by entering the line pressure into the controller.

The TELEDYNE 8800B Trace Moisture Analyzer operates on a common electronics platform featuring a microprocessor with advanced user options. Key functions include dual adjustable alarms, 0–24 mA or 4–20 mA isolated outputs, RS-232 communication, and built-in self-diagnostics performed at startup and every two minutes thereafter. The system also provides clear indications for sensor faults or electronic failures.

Installation best practices involve placing the sensor and instrument as close as possible to the measurement point, minimizing leaks, and avoiding excess fittings upstream to reduce potential moisture accumulation. With these guidelines followed, the analyzer delivers reliable, real-time moisture monitoring that meets today’s demanding industrial standards.

In short, the TELEDYNE 8800B Trace Moisture Analyzer combines cutting-edge HTF sensor technology with robust electronics and user-friendly features to deliver precise, fast, and stable trace moisture measurements in even the most challenging environments.
