Introduction

ZR-1 3-Digit Wideband Air/Fuel and Lambda Gauge

The ZR-1 gauge is only 6/8″ (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can be surface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The ZR-1 base allows the gauge to be mounted in a standard 2 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size).

The Gauge works with all versions of the Zeitronix Zt-2 Wideband AFR meter and Datalogging Systems and Zt-3 Wideband AFR Meter. The ZR-1 plugs into the Zt-2 or Zt-3 DATA port and can be used while datalogging.

Clean and easy plug and play installation: power and display information is provided using one wire connecting to the Zt-2 or Zt-3 DATA port. The ZR-1 cable length is 5 ft (1.5m) and can be extended if needed.
