DieselOp Opacity Meter Features:

• Stores up to 100 tests

• Designed for simplicity, portability and consistent reliability.

• Accurate to within 1% of readings in both artificial and direct lighting.

• Optional sensor styles to suit any application. In-line systems are available.

• Allows for testing in both a “snap -idle” mode, or “follow mode”. Both tests can be performed in either raw or filtered data.

• Available with full flow or partial flow sensor head.

• Both sensor heads use the same transmitter and receiver, and can be easily interchanged. Expanded yokes allow for readings up to 24″ stacks.

The partial flow sensor head is constructed out of light weight anodized aluminum. It comes with a straight and curved nozzle for easy placement on varied stack configurations. Our unique design allows for the passage of the smoke plume past the optics, without the need for a fan.The partial flow head allows for quick and easy placement of the sensor on the stack. The bayonet style nozzle slips into the stack, reducing the possibility for any wind distortion while testing. A clamping style nozzle is also available for quick and easy placement.The full flow head is an end of line sensor. The light source and receiving unit measure opacity directly across the diameter of the exhaust stack.The optics are protected from the smoke plume by a set of baffles. The head is attached to the stack with a universal band clamp and a set of magnet clamps which hold the sensor head in place. Full flow heads are less susceptible to heat build-up and pressure created by the exhaust during testing.
The complete system consists of a control unit, sensor head assembly, printer, software on CD, extension pole, various connecting cables, calibration filter, instruction manual, and a carrying case.
