One gauge for displaying Wideband AFR /
Lambda, Boost / Vacuum, EGT, andthe Zt-2 "User2" input values
such as E% (Ethanol Content) air/oil/transmission temperature, fuel/oil pressure, voltage or a 2nd AFR/Lambda
when in a Dual
Channel AFR/Lambda Display configuration
4 digit readout available in Blue or Red
Stylish, machined, brushed aluminum or anodized black bezel and slim
enclosure gives the gauge an elegant appearance
User configurable outer LED and inner digital readout
values via a front push button
Gauge startup setup is configurable
capabilities using the Zeitronix ZAVT-1
Alarm/Trigger. Monitor and trigger on single values or combinations of
AFR, Boost, RPM, TPS, EGT, Oil/Fuel Pressure and Air/Water temperatures.
No PC laptop required for gauge configuration. Cycle through displayed values at any time using
the front push button.

High contrast LED display
Large 0.3" (7.5mm) digits
Slim 0.75" (19mm) flat back design for flexible gauge mounting options
Requires Zeitronix Zt-2 for operation.
The ZR-2 Multi Gauge works with all versions of the Zeitronix
Zt-2 Wideband AFR meter and Datalogging System.
The ZR-2 Multi Gauge plugs into the Zt-2 DATA port. Power and serial data is supplied directly through the single connector.
No additional +12V or ground wires required. The ZR-2 Multi Gauge cable length is 5 ft (1.5m).
Fail-Safe Operation Add robust failsafe gauge features using the
optional relay. The Zt-2 Wideband controller will monitor user set
levels triggering the ZAVT-1 Warning/Trigger box and optional relay if one
or a combination of values exceeds limits. Trigger a failsafe condition on
any Zt-2 input including AFR, Boost, RPM, TPS, EGT, Oil/Fuel Pressure,
Air/Water temperatures and more. Create a failsafe gauge with the Zt-2
controller watching both displayed values and any other connected sensors or
inputs. This simple failsafe safeguard is a great way to
protect your engine, hardware and time investment.
Dual Channel Wideband AFR Dual
channel AFR readings are available with two AFR readings being
displayed on one ZR-2 gauge. The outer edge of LEDs supply one AFR
reading while the inner digital readout shows the second air/fuel ratio.
Multiple display and datalogging options are available running a dual
Multiple Gauges Supported
A splitter is included with each display allowing up to 3 displays to be
linked to single Zt-2.
The ZR-2 gauge is only 3/4" (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-2 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
