MG101 GE Portable Moisture Calibration Generator
MG101 manufactured by GE Panametrics is a fully mechanical portable dew point calibration generator used for on-site verification and calibration of aluminum oxide moisture probes and hygrometers. It generates stable and repeatable trace moisture vapor via gas dilution, covering dew/frost point range from -75°C to +10°C. The unit requires no external power supply and features inherent explosion-proof design, suitable for hazardous industrial zones. Equipped with precision flowmeters and pressure regulating components, it connects with dry nitrogen source to produce calibrated test gas. Widely used in natural gas, semiconductor and petrochemical facilities, it serves as essential calibration equipment to ensure long-term measuring accuracy of moisture monitoring systems and supports regular instrument maintenance without laboratory transportation.
Description
MG101 GE portable moisture calibration generator is a professional field calibration device developed by GE Panametrics for trace moisture measurement instruments. Unlike bench-top calibration equipment limited to laboratories, this compact mechanical unit enables direct on-site calibration of moisture probes without removing sensors from process pipelines, greatly reducing equipment downtime for production lines. It adopts single-stage or two-stage gas dilution principle to mix dry carrier gas and saturated wet gas, outputting gas with precisely controllable water vapor concentration for sensor testing. Every unit undergoes strict factory verification of flow linearity, dew point stability and air tightness before delivery.
The equipment operates without electricity and only requires a stable supply of high-purity dry nitrogen or ultra-dry compressed air. Internal multiple precision rotameters allow technicians to adjust dilution ratio flexibly, continuously changing output dew point to complete multi-point calibration. The generated dew/frost point spans -75°C up to +10°C, corresponding to moisture concentration from 1.2 ppmv to 12120 ppmv under standard atmospheric conditions, covering most common industrial trace moisture monitoring scenarios. Built-in pressure gauge and regulating valve maintain stable inlet pressure, ensuring consistent test gas parameters during long calibration cycles.
With an inherently explosion-proof mechanical structure, MG101 can be safely deployed in flammable and explosive working areas such as natural gas compressor stations and chemical process workshops. The stainless steel gas pipeline and standard 1/4” tube fitting interfaces support quick connection with sampling cells and moisture probes. After connecting the probe to the output port, users can record probe readings under different calibrated dew points to judge drift degree and complete compensation adjustment.
Long-term online moisture probes inevitably produce measurement drift caused by surface contamination and aging. Regular calibration with MG101 effectively avoids inaccurate moisture data leading to process abnormalities, catalyst failure or unqualified finished products. When traditional laboratory calibration brings high disassembly and transportation costs, this portable generator provides an economical maintenance solution.
It is widely matched with GE MISP2, MIS2 series moisture probes and IQ series moisture analyzers. After simple pipeline assembly and flow stabilization, calibration work can be launched rapidly. The integrated carrying handle facilitates movement among multiple monitoring points inside the plant.
Combining wide adjustable dew point range, power-free operation and portable design, MG101 GE moisture calibration generator is a preferred field calibration tool for industrial trace moisture measuring systems. It guarantees reliable measurement performance of moisture monitoring equipment and supports safe, stable and high-quality operation of industrial process production facilities.
