In special scenarios such as factories, airports, and monitoring stations, industrial safety inspections are the first line of defense to protect safety. Facing the equipment price ranging from 20,000 yuan to 200,000 yuan in the market, how can buyers penetrate the marketing and choose truly reliable equipment? This article will reveal 9 key questions that must be asked for professional purchasing.
1. Three core technologies Question 1. \”Can the detection accuracy be divided into metal material?\”
In industrial scenes, we need to identify the difference between tool (iron products) and tool (alloy alloy). Beware of equipment that is labeled \”test sensitivity\” to avoid material quality identification. In fact, it is required to compare the alarm difference between iron sheets with a diameter of 0.5 cm and copper sheets with homogeneous copper sheets.
2. \”Does the resistance to joint movements manifest?\”
In logistics parks and other areas, suppliers are required to demonstrate the stability of the simultaneous work of the three-stage equipment. High-quality equipment should have dynamic frequency adjustment technology to avoid errors caused by electromagnetic stimulation.
3. \”Misreport rate in extreme environments?\”
Train equipment to the car to measure the performance of metal powder and static electricity stool environments, and record the number of error reports within 30 minutes. The pass standard should be <3 times/hour.
2. Exploration of hidden costs
4. \”What is the proportion of module design?\”
Inquiry whether core components such as motherboards and sensors support single replacement. Because a certain brand adopts a one-piece design, the repair cost is as high as 70% of the equipment price, while the repair cost of modular equipment can be controlled within 30%.
5. \”The maintenance cost behind energy consumption?\”
Requires viewing of the 24-hour operating fee measurement data. Because of the use of old-fashioned electromagnetic coils, the annual electricity consumption cost of a certain imported equipment is 1,200 yuan higher than that of a new domestic equipment.
6. \”Software System Updates Charge Mode?\”
Beware of the text game \”Free Upgrade\” and ask clearly:
Is it charged for function iteration? >
Is the database update independent fee?
The ratio of cross-version upgrade fee
3. Supplier Capacity Verification Method
7. \”Can you provide a video of the same-commercial case?\”
Requires viewing of target industries (such as automobile manufacturing/chemical/monitoring) The actual operational record of the key points:
Personnel pass speed (qualified line > 25 people/min)
Alert alarm delay (responsible <0.3 seconds)
Log Recording Integrity
8. \”Why should the field engineer\’s response be half the time?\”
The quality supplier should state in the contract:
100 public Arrive in 4 hours
Interprovincial support shall not exceed 24 hours
At least twice a year
IV. The ultimate calculation formula for sex price ratio
9. \”Full Life Cycle Cost Model?\”
Use this formula to compare the quotes:
(equipment price + 5-year maintenance fee) ÷ Average daily test number ÷ years of service
A case shows: Equipment A is priced at 120,000 yuan, with a cost of 148,000 yuan in five years; Equipment B is priced at 180,000 yuan, with a cost of 192,000 yuan in five years, but Equipment B is more efficient than Equipment B, and its cost of single inspection is 23% lower than that of 23%.
