Portable Hydrogen Purity Analyzer we are indigenous manufacturer of portable hydrogen Purity Analyzer to check the Hydrogen Gas Purity from cylinder and Hydrogen Line. Model ATS 202A microcontroller based hydrogen purity Analyzer which can measure the hydrogen Can concentration with the range of 0-99.99% V/V with resolution 0.01 %. Hydrogen Purity Analyzer has provision to control the gas Flow for precise measurement. Instruments Hydrogen Purity Analyzer consist the Lithium rechargeable battery. To check the hydrogen Purity we used thermal conductivity technology for accurate measurement of Hydrogen concentration. Long life Thermal conductivity sensor makes the instruments very reliable and accurate. Model ATS 202A has provision to store the data up to 3500 with customized time interval and we can retrieve the logged data to computer with the help of USB computer interface.
