Verify the engine’s air/fuel ratio and emissions compliance for optimum efficiency and compliance with government regulations. 

“Know before it ever even leaves the shop that efficiency is where it should be.”

Smoke Opacity MeterSmoke Opacity Meter for real-time monitoring of diesel engine’s exhaust stack emissions (on the meter’s integral LCD) with output for simultaneous data capture and display via optional DYNOmite data-acquisition computer and DYNO-MAX. Adjustable stack-mounted sensor adapts to most diesel exhaust stacks. Integral 12-volt supply battery plus 120-volt AC supply allows on-highway, or in-shop, testing. Analog output jacks and harness for connecting to DYNOmite-Pro data-acquisition computer with DYNO-MAX software.

Part # 430-170 (includes full-flow head - as shown)

Exhaust Measuring SystemExhaust Measuring System five-gas analyzer for real-time monitoring of engines emissions during chassis or engine dynamometer testing. Large integral LCD panels. Simple user interface includes both manual and automatic zeroing, low-flow warnings, out-of-range detection, etc. five-gas analyzer includes O2 (0-25%), CO (0-10%), CO2 (0-20%), HCs (0-2000 ppm), and NOX (0-5000 ppm) readouts. Lambda and AFR are also calculated and displayed when using the (all digital) link to a PC running the optional DYNO-MAX software. (Requires an available RS-232 serial port and DYNO-MAX standard or “Pro” software). Integral vacuum pumps and water separator make the system compact and easy to maintain. Flexible stainless-steel tailpipe “sniffer” probe and 25' hose includes quick disconnect coupling. Less than five-minute warm-up time with typical accuracy of ±1% (or better) of full scale. Fast response time < 9 seconds to 90% of actual. 12-volt lighter plug DC operation allows the DYNOmite EMS to go on the road for real-world emissions monitoring (also includes 120-volt AC supply).

Part # 430-175 (includes tailpipe sniffer and hose - not shown)  

Air/Fuel Ratio Exhaust Sensor ModuleAir/Fuel Ratio Exhaust Sensor Module and harness for measuring the engine’s mixture on the dyno or road. Its ultra-wide 9 through 16 A/F Ratio range DYNOmite sensor is broad enough for high-performance gasoline-engine tuning. (Works with most pump fuels.) Sensors are individually offset-trim matched, so multiple sensors can be used for cylinder-to-cylinder comparison testing (with one switch-controlled module). Outputs include both a near-linear 0-5 volt analog signal (requiring no correction mapping over most of its working range) and an (all digital) RS-232 link to DYNO-MAX. The digital interface avoids the multiple analog conversion errors – common in other units! This system’s typical accuracy of ±2% (or better when near the stoichiometric ratio) and fast response time make it suitable for even many research laboratory grade, transient dynamometer test programs. Semi-automatic offset calibration in free air allows for easy field verification. (Requires available 0-5 volt channel and DYNO-MAX software.)

Part # 430-186 (single channel - call for multi-channel applications) 

Air/Fuel Ratio Exhaust Probe PumpAir/Fuel Ratio Exhaust Probe and Pump with harness for measuring a vehicle’s mixture from its tailpipe – during chassis dyno testing. This kit combines our AFR module (#430-186) with a reliable vacuum air pump – for extracting hot sample gases at the tailpipe outlet. The pump is powered directly from your shop’s compressed-air supply. The extra-long (bendable) sampling tube avoids fresh-air dilution and sensor-damaging water vapor separation. Your O2 sensors stay accurate and cleaner longer – without constant filter-jar maintenance hassles. The adjustable retention hardware adapts the probe and pump to almost any vehicle’s tailpipe configuration. A remote mount Pulse Dampening Pump Hose kit (#430-189) should also be ordered for most bikes and single-cylinder exhausts. (Requires an available 0-5 volt channel and DYNO-MAX software.)

Part # 430-182 (includes O2 sensor module and vacuum pump - as shown)
Part # 430-179 (optional pulse-dampening line - for single-cylinder exhausts)
