Working Principle & Core Performance

This equipment relies on dry nitrogen as the only gas source. Dry gas is split into two paths: one path passes through a saturator to form saturated wet gas, then mixed with pure dry gas through primary dilution and secondary dilution to output controllable and repeatable dew point gas samples. The adjustable dew/frost point range covers -75°C ~ +10°C, with calibration accuracy up to ±1°C, meeting the trace moisture calibration demands of industrial gas monitoring equipment. Equipped with four precision rotameters with regulating valves, pressure regulators, filter elements and built-in temperature gauges to realize visual flow regulation and real-time temperature reading. The whole set adopts pure mechanical structural design with no electronic components, inherently explosion-proof, applicable to flammable and explosive industrial sites. Stable gas output effectively eliminates measurement drift faults of moisture sensors caused by long-term online operation.

Structural Characteristics & Environmental Adaptability

Integrated compact cabinet layout with small overall volume for easy transportation and field deployment. Internal gas pipeline components are made of corrosion-resistant stainless steel to avoid medium contamination during gas preparation. Each gas circuit interface adopts sealed connection structure to prevent gas leakage during calibration operation. The device has no vulnerable electronic circuits, resisting temperature fluctuation, vibration and dust interference in chemical plants, gas stations and power workshops. The overall structure has good shock resistance, adapting to mobile use in complex field working environments.

Matched Equipment & Application Scenarios

Mainly supporting the calibration of GE MISP2, MIS2, MTS5 series moisture probes and IQ-110-00 online dew point analyzers. Widely used for periodic calibration of hydrogen dew point monitoring equipment in thermal power plants, natural gas pipeline moisture measuring instruments, compressed air drying system detectors and petrochemical process gas moisture analysis equipment. It corrects measurement deviation of aging probes on site, guarantees the accuracy of process gas quality monitoring data, and reduces instrument offline calibration cycle and maintenance cost.

Stability & Maintenance Advantages

The mechanical gas circuit structure has extremely low failure rate and long service life; each component is inspected for air tightness and flow consistency before factory delivery. Daily maintenance only needs regular replacement of filter consumables and cleaning of the saturator bottle, with ultra-low maintenance threshold and operating cost. Original MG101 calibration source can provide traceable standard gas environment to avoid measurement errors caused by unqualified calibration tools. Shockproof integrated packaging is suitable for long-term storage and mobile transportation of spare equipment, and the gas path performance will not degrade under dry storage conditions.
