KTG151 Explosion - proof Dew - point Meter (Online Explosion -
proof Type) for Semiconductor Industry
Introduction
The KTG151 explosion - proof dew - point meter is an explosion -
proof dew - point meter developed by our company. It adopts an
imported polymer - material capacitive - resistive dew - point
sensor to quickly measure the trace water in gases in explosion -
proof scenarios.
Application Areas
Petrochemical industry, natural gas, industrial gases,
semiconductor industry, drying industry, food industry, electric
power industry, machinery manufacturing, air separation industry,
pharmaceutical industry.
Instrument Characteristics
- It adopts an original imported polymer - material capacitive -
resistive high - precision and fast dew - point detector.
- It automatically compensates for temperature and pressure to
eliminate the influence of the temperature and pressure of the
detected gas on the measurement.
- It adopts a flame - proof design.
- It has a full - Chinese man - machine dialogue menu, and infrared
remote - control operation is intuitive and convenient.
- The instrument is equipped with a high - performance embedded
integrated TFT true - color display screen, which can
simultaneously display parameters such as the measured value,
historical curve, range, and status. All instrument parameters can
be configured, calibrated, and tested in the form of full - Chinese
remote control. Historical records and curves can be set according
to time.
- It can perform mutual conversion among dew - point in °C, ppmV, and
absolute humidity.
- Alarm points and upper - and lower - limit control points can be
arbitrarily set within the full range.
