Introduction
Introduction
The OmiSmoke diesel smoke meter (DSM) is an exhaust smoke analyser for diesel
vehicles and is available as both a stand-alone and PC-based unit. It is an opacimeter
device working on the partial flow principle.
The OmiSmoke is approved by the Vehicle Inspectorate Executive Agency for MOT
testing on the following classes of vehicle:
•Category A - Cars and Light Commercial Vehicles (MOT classes 4 and 7)
•Category B - Public Service Vehicles, Private Buses and Heavy Goods Vehicles
(MOT Class 5 and 6)
OmiSmoke consists of two portable units; the smokemeter, which contains the
measurement electronics, and the handset, which is equipped with a 4 button keypad,
LCD display and a printer. The two units are connected by a single 7 meter cable.
The smokemeter is designed to run for intermittent operation on an internal 12V
200W battery, or using the AC adapter if prolonged supply operation is required. The
smokemeter can be charged when not in use by leaving the AC adapter connected.

Sample hose
The exhaust probe collects gas samples from the test vehicle exhaust, which are then
analysed by OmiSmoke.
Take care to avoid contact with the exhaust system when inserting or
removing the sample hose. The exhaust system will be hot and severe
burns could occur.
