MEXA-1170HFID

Overview

With 14 selectable ranges - from 0-10 ppmC to 0-200,000 ppmC - MEXA-1170HFID can measure direct (raw-exhaust), CVS/tunnel-diluted, and evaporative-emission samples.

A ten-key control pad and a color LCD make it easy to monitor the test data. Data transfer to a remote computer is possible via RS-232 or an optional analog output.

Applications

Includes everything necessary to analyze the following samples:

  • Direct (raw exhaust)
  • CVS/tunnel
  • Evaporative emission (from SHED)

Supports testing of the following engine types (items with an asterisk require optional heated filter):

  • Gasoline
  • Diesel*
  • Methanol
  • LPG
  • CNG
  • Two-cycle*
  • Four-cycle
  • Small utility engines* (e.g., lawn mowers)

Features

  • Slim, compact case houses HFID detector, sampler, and control unit.
  • Stand-alone operation for a variety of applications.
  • Exceptionally wide range of concentrations.
  • Easy transport and operation.
  • HFID based on MEXA-7000 series - world standard instrumentation for emission analysis.
  • Digital input/output via RS-232 connection.

Options

  • Heated filter with sample probe
  • HF-04: for diesel engines and direct-injection gasoline engines
  • HF-05: for two-cycle engines and general purpose engines
  • Heated line for sample-inlet connection, 2/3/4/6 meter, 113/191°C
  • Temperature controller for heated filter and line
  • Analog output: 0-1/0-10 V
  • Leak check function
  • Cart
