Measuring the air-fuel ratio is essential for addressing engine exhaust emissions and reducing fuel consumption. We would like to introduce the portable PLR-7 for control system development applications.
This is a compact and lightweight air-fuel ratio meter utilizing a layered zirconia ceramic UEGO sensor. By simply attaching the sensor to the exhaust pipe, you can easily measure the air-fuel ratio. Features: > Compact and lightweight with easy operation > Wide dynamic range (9.5–60 AFR) > Fast response time of T10-90 < 250 ms > Compatible with DC 12V operation (suitable for in-vehicle measurement) > Fully compatible with PLR-5 (previous model) > Selectable analog output of 5V/10V > Standard equipped with RS-232C, USB, and LAN FAQ Can the PLR-7 be used for performance testing of hydrogen engines? Our air-fuel ratio meter can also be used for performance verification of hydrogen engines. Please contact us for more details. Is it compatible with alcohol-based fuel engines? It can accommodate all engines, including hydrocarbon and alcohol-based fuels, as it allows you to set the H/C and O/C ratios of the fuel. Can the sensor for PLR-5 be used with PLR-7? Yes, it can be used. The parameters can also be used as they are.
