Jamar Distance Measuring Instruments |
These cost-effective units save time and money by allowing personnel to measure distance, accurate to 1 foot per mile, while driving as fast or slow as necessary.
SRAC+I-IO-K RAC Plus I (instrument only) - Comes with the RAC Plus I instrument, manual and brackets. Does not include modular distance sensor or installation kit.
SRAC+I-MS-K RAC Plus I DMI with vehicle kit and modular sensor - Comes with the RAC Plus I instrument, manual and all equipment needed to install it in a vehicle, including modular distance sensor, installation cables and brackets.
SRAC+I-OBD-K RAC Plus I with AutoLink OBD Distance Sensor - Comes with RAC Plus I instrument, manual and all equipment needed to install it in a vehicle, including AutoLink OBD sensor and brackets.
 The RAC Plus I brings the accuracy, reliability and productivity of using a vehicle installed distance measuring instrument within the reach of everyone. All distance and speed information can be read directly from the RAC Plus I's display - no software is required to view your data. This unit is a replacement for our older model RAC-100 DMI.
• New Smaller Case
Light weight, high-impact ABS plastic case (7.8"W x 2.3"H x1.2"D) allows you to mount DMI to the front of the dash board or virtually anywhere inside the vehicle.
• Dual LED Displays
Dual 6-digit LED Displays are easy to read at any angle both day & night. The dual displays separate distance
data from speed, calibration number, vehicle number, time and menu selections.
• Four Brightness Levels
Select the level best suited for ambient light conditions.
• Menu Driven
Simplifies user selection for various operational capabilities.
• Automatic Calibration
Allows quick, simple calibration on all vehicles. Stores four separate vehicle calibration numbers for multi-vehicle usage.
• Pre Distance
Pre-Distance if starting at a known point, count up/down or add/subtract distance from current display.
• Count & Display Hold
Freeze the display while continuing to accumulate distance with Display Hold or stop accumulation of distance with Count Hold.
• Interval Distance
Display distance intervals between points of interest (i.e. Telephone Poles, Signs, Pavement, Markings, etc.)
• Distance Conversion
With a simple push of the Unit key, convert distance from Feet to Miles to Kilometers.
• Distance Pulse Output
Send calibrated distance pulses to a lap top computer or ancillary equipment. The interval and duration of the output signal are user selectable from key board.
• Dependable
A power-on self test (POST) is performed each time the DMI is turned on. As part of the POST, the calibration number is displayed for your verification.
SRAC+III-10-K RAC Plus III (instrument only) Comes with the RAC Plus III instrument, manual and brackets. Does not include modular distance sensor, installation kit, or GPS system. Optional RACPro software sold separately.
SRAC+III-MS-K RAC Plus III with vehicle kit and modular distance sensor - Comes with the RAC Plus III instrument, manual and all equipment needed to install it in a vehicle, including modular distance sensor, installation cables and brackets. Optional GPS receiver and interface box for the receiver sold separately.
SRAC+III-GPS-MS-K RAC Plus III w/GPS, Modular Distance Sensor & Vehicle Installation Kit - Comes with the RAC Plus III instrument, GPS receiver & interface box, manual and all equipment needed to install it in a vehicle, including modular distance sensor, installation cables and brackets.
SRAC+III-GPS-OBD-K RAC Plus III w/GPS System & AutoLink Distance Sensor - Comes with RAC Plus III instrument, GPS receiver & interface box, manual and all equipment needed to install it in a vehicle, including AutoLink sensor distance sensor and brackets.
SRAC+III-OBD-K RAC Plus III w/AutoLink OBD Distance Sensor - Comes with RAC Plus III instrument, manual and all equipment needed to install it in a vehicle, including AutoLink distance sensor and brackets. Optional GPS receiver and interface box for the receiver sold separately.
 The RAC Plus III takes all the benefits of the RAC Plus I and adds the ability to record and store events to the unit's expansive memory. This unit also comes with GPS recording capability creating an unparalleled combination of accuracy & convenience. This cost-effective unit saves time & money by allowing personnel to measure distance, accurate to 1 foot per mile, while recording GPS coordinates of roadway features - making it the most powerful DMI on the market.
Record Accurate Distance along w/GPS Coordinates
Exclusive only with the RAC Plus III/GPS, you are able to store up to 30 hours of continous GPS data, at one second intervals, while recording roadway distance in the RAC Plus III's internal memory. Using this powerful inventory tool, you can record road features (intersections, bridges, signs, guide-rail, etc.) along with their distance and GPS coordinates.
Unmatched GPS Recording Accuracy
The RAC Plus III uses a GPS receiver which incorporates the Wide Area Augmentation System (WAAS) for improving accuracy of GPS signals. WAAS uses a correction signal created by a collection of 25 land-based stations that are spread out across North America. This correction signal is then broadcast from specialized communication satellites.
With WAAS enabled, our 12 channel GPS receiver capability allows 2D GPS accuracy of approximately 2 meters. Without WAAS, depending on the location in the continental US and satellite accessibility, horizontal GPS accuracy is approximately 6 meters. This, along with the RAC Plus III's distance accuracy of +/- 1 foot per mile, provides unequaled data collection capabilities.
Several Data Retrieval & Processing Options
In its most basic configuration, you can simply record and then read the distance and GPS informaion off of the the RAC Plus III's display. This can be done while the vehicle is stopped, or while it is moving, depending on the number of people doing the data collection.
A more efficient method is to have the RAC Plus III store the events of interest, along with their distance, latitude & longitude, as you key them in. When using this method, the GPS coordinates can be stored every second while roadway events, with their distrance & lattitude/longitude, are stored as you enter them. This data can then be easily downloaded to the RACPro processing software for analysis, reporting or exporting to external software like Excel or commercially available mapping programs.
