EPM1601 - Gas Analyzer
For Petrol/LPG/CNG Vehicles

6Gases
Instrument is easily upgradable to measure concentration of 6 gases (NOx, SOx in addition to CO, HC, CO2 and O2).
AutoZero
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.
eLeakCheck
Automatically performs leak-check before any measurement thus aiding user to identify leak if any. It also helps ensure accuracy of measurement.
AutoControls
Helps to switch on/off pump, solenoid valve etc automatically after the respective functions are performed thus increasing the life of the instrument.
SDiagnosis
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.
PowerSaver
Switches off the display after 5 mins of inactivity thus reducing power consumption.
USB
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.
MultiTechRPM
Equipped with RPM sensors capable to measure RPM using Piezo/Battery/Acoustic/Vibration principles thus ensuring zero downtime.
WLRemote
Wireless remote based on bluetooth technology averts use of cables (optional).
WLRPMSensor
An optional wireless RPM sensor for smooth functioning.
WLPrinter
Wireless dot-matrix printer for user-friendly operations (optional).
i3SysRemote
An android application to communicate between the instrument and any android mobile phone. App can be downloaded from Google PlayStore.
Emitso
A Windows/Android application for vehicle emission tests. Emitso is 2way communication enabled thus helping operators use either the instrument or the PC while carrying out emission tests. Emitso can send SMS reminders to vehicle owners to renew their emission test certificate. Emitso can generate MIS reports for the use of PUC Centers.
