AT – M3 HANDHELD FOR LOW SPEED

The design is novel, the style is small, the use is light, and the sensitivity is high. Three Technical indicators

1. WorkPerformance

• Speedmeasurement accuracy:  ±1km/h.
• Speed measurement range:0-321km/h;
• Workingdistance:

For  large  vehicles,  the  working  distance  is  ≥500  m; For  small  cars,  the  working  distance  is  ≥300  m;

2. Electricalparameters

• Operatingvoltage:  nominal value +12VDC, maximum +16V, minimum +10.5V.
• Workingcurrent: When the working voltage is +12VDC, the working current is ≤0.2A.
• Microwave transmission  frequency:  K  band

(5)  Radar beam width:  ±16° at 3dB.

Other technical parameters of the radar speedometer: Microwave data:

Antenna type:  flat panel array antenna Lens type: accurately reflected Polarity:  bipolar cycle

Radar frequency: K band

Basic data:

Small size:  160×85mm

Light weight: 788g (with lithium battery) can be used for 10 to 20 hours

Features: Low-cost, very practical low-speed speedometer, without printing, built-in 12v2800ma lithium battery, do not need to have their own battery, Dr. can speedometer 2 Yuan per week Nanfu battery, it is 10usd , 1 At least 2 batteries are used in a week, and the cost of a battery in a month is more than 30usd. Compared with the quality of the doctor’s speedometer, the accuracy is high and the price is low.
