EPM1602 Gas Analyzer

EPM1602 - Gas Analyzer For Petrol/LPG/CNG Vehicles

Features :-


WaterSense helps detect any water content from the sampling system into the instrument and turns off the pump and stops suction thus prolonging the life of the instrument.


Instrument is easily upgradable to measure concentration of 6 gases (NOx, and SOx in addition to CO, HC, CO2 and O2).


The accuracy of the NDIR sensor depends upon temperature factors. Any change in the temperature results in change in the measured values. AutoZero ensures to zero measured values for every 20 minutes by default or for every 2°C change in the temperature.


Automatically performs leak-check before any measurement thus aiding user to identify leak if any. It also helps ensure accuracy of measurement.


Helps to switch on/off pump, solenoid valve etc automatically after the respective functions are performed thus increasing the life of the instrument.


Checks various functional parameters like HC-residue, warm-up, leak, low flow etc. Assists in detection of faults/failures like O2 sensor failure, NDIR sensor communication failure etc.


Switches off the display after 5 mins of inactivity thus reducing power consumption.


Equipped with an USB (as well as RS232) interface for easy communication. USB serves as a backup interface when RS232 interface fails. Moreover, present computers are not equipped with RS232 port.


Equipped with RPM sensors capable to measure RPM using Piezo/Battery/Acoustic/Vibration principles thus ensuring zero downtime.


Wireless remote based on bluetooth technology averts use of cables (optional).


An optional wireless RPM sensor for smooth functioning.


Wireless dot-matrix printer for user-friendly operations (optional).
