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.
