Zetron Instrument focuses on providing customized solutions for precision analysis and monitoring.
Product Description
The high-precision portable dynamic gas calibration instrument is flexibly configured with dilution ratios ranging from 1:1 to 1:2000, which is adjustable to meet various stringent test calibration requirements. It is widely used in multi-point calibration, linear verification and performance evaluation of laboratory chromatography, portable GC, gas monitoring instruments and gas alarms.
Features
High accuracy: the linear correlation coefficient of flow is as high as 0.9999.
High dilution ratio: the dilution ratio can reach 1:2000, which can flexibly respond to different needs.
Inert flow path: full flow silanization to reduce adsorption and residue.
Low power consumption: battery life exceeds 6 hours, stable and worry-free operation.
Intelligent reminder: built-in reminder for timely operation and maintenance.
Program output: program multi-level programmable, which can automatically adjust dilution ratio and flow rate.
Flexible power supply: built-in battery is compatible with AC/DC power supply, adapting to multi-scenario needs.
Historical data: historical data can be stored for easy backtracking and analysis.
Pressure control: optional electronic pressure regulator for automatic injection of chromatographic analyzers.
Applicable standard:ISO 6145-7:2018 - Gas analysis — Preparation of calibration gas mixtures using dynamic volumetric methods — Part 7: Thermal mass-flow controllers.
