A1: We're original manufacturer, which can help you get factory selling products with competitive prices.
Q2: How long is your delivery time?
A2: Normally it is 3-10 working days if the goods are in stock. Or it is 10-25 working days if the goods are not in stock, it is according to your order quantity.
Q3: How is your after-sale service?
A3: Our experienced technical team is ready to respond you within 24 hours.
Q4: What is your MOQ? Do you provide customized services?
A4: For sample order, there is no limit on MOQ. We will appreciate it if you'd like to purchase samples for testing first.
Q5: What is your terms of payment?
A5: Payment≤5000USD, 100% in advance. Payment>5000USD, 30% T/T in advance, balance before shipment. Trade Assurance order payment. Paypal, Western Union etc.
Q6: Can I become your sole distributor in my place?
A6: We appreciate that. And we will discuss about your market situation together and after confirmation we will send you a contract with detail requirements about distributor terms and sales targets.
Q7: Is it possible to measure the distance in the place where the rangefinder has a horizontal surface and outdoors during the day? why?
A7: No, the water surface will affect the light reflection signal back, and the sunlight during the day will also cancel the signal.
Q8: How many meters does the reflector of the rangefinder have?
A8: Above 80 meters.
Q9: What is the difference between red light and green light of rangefinder?
A9: Red light is 635nm, large wavelength, low frequency, low laser loss. Green light is 500-535nm small wavelength, high frequency, short wavelength, strong energy, strong penetrating power, and clearer outdoors.
Q10: Is the laser rangefinder red light or green light better?
A10. According to the customer's use occasion: red light for indoor use, which has the advantage of multiple models, practical and cost-effective; for outdoor use, choose green light, which is clearer when the light is good during the day.
Knowledge points: the wavelength of green light is 500~560nm, the beam can carry more; the wavelength of red light is 605~650nm.
Q11: What is the scope of our test with POE?
A11: PoE switches in the range of 12V-60V can be tested.
Q12: What is the error range of the company's rangefinder?
A12: The error is plus or minus 2-3 mm.
Q13: According to safety standards, the laser of the laser rangefinder has the following types:
A13: According to safety standards, the laser of laser rangefinder has the following types:
Class Ⅰ Not regarded as dangerous goods.
Class Ⅱa This class is classified as a laser in the visible light band from 400 to 710nm. Observation within a certain fixed time (1000 seconds) is not dangerous, but chronic observation over 1000 seconds is judged as dangerous.
Class II This class is classified as a laser in the visible wavelength range of 400 to 710nm, and chronic long-term beam observation is judged as dangerous. Generally speaking, this kind of disgusting reaction (blinking) of the eyes can protect long-term observation from harm.
Class IIIa Although it depends on the radiation level, chronic and transient laser observations are dangerous. It is also dangerous to use optical instruments to observe the laser directly.
Class IIIb Even if it is an instant, direct laser irradiation on the skin or eyes is dangerous.
Class IV Even if it is a moment, direct laser beams on the skin or eyes will be dangerous, and the diffused reflected light will also be dangerous to the skin or eyes. General handheld laser range finder is required to be no less than class Ⅱ.
