Jamar Distance Measuring Instruments |
| Accurate, reliable and easy to operate, our RAC Plus units are THE BEST distance measuring instruments on the market. 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. They also incorporate our exclusive modular distance sensor technology to provide you with the highest degree of accuracy. Much safer than the old 'Hand-Wheel', these units will pay for themselves in increased productivity in a matter of days. The RAC Plus series of DMIs replace the older RAC-100 and RAC-200 units, which were originally introduced in 1993 and quickly became an industry favorite. The RAC Plus series offers new features and improvements to the older RAC-100/200 units.
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.
 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.
• Extremely Accurate
Distance measurements accurate to 1 foot per mile, even at slow speeds.
• Change 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 or installation kit.
SRAC+III-MS-K RAC Plus III with vehicle kit and modular 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.
SRAC+III-GPS-IO-K RAC Plus III w/GPS with vehicle kit and modular sensor - Comes with the RAC Plus III w/GPS instrument, manual and all equipment needed to install it in a vehicle, including modular distance sensor, installation cables and brackets.
 The RAC Plus III takes all the benefits of the RAC Plus I and adds the flexibility of GPS compatibility, credting an unparalleled combination of accuracy and 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 stop at each point of interest and write down the distance, latitude and longitude from the instrument's digital display.
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.
Another option is to connect the RAC Plus III directly to a computer running WinRAC Plus in the field.
SRAC-MB-W-K Windshield mounting bracket
SWINRAC PLUS-K RAC Plus III Software program, Windows (98, 2000, ME, XP) compatible. Allows easy data retrieval, edit and report capability. Direct interface to laptop for real time data communication. Supplied with RS-232 cable, power supply and manual.
SRAC-GPS-R GPS Receiver for use with RAC Plus III\GPS Instrument (*Requires GPS Receiver Data Interface)
SRAC-GPS-DI GPS Receiver Data Interface (*Requires GPS Receiver)
NOTE: Always specify make, year and model of vehicle when ordering. An optional adapter kit or speed sensor may be required.
