           Photos

If necessary we can take photos of a device from various angles.

      Technical Documentation

In case you didn't find in technical specifications for the device all necessary information you are interested in, feel free to contact me.  I will look through the technical documentation for the device and I will be happy to consult you.

Also I may speak directly with the manufacturer and find out more specific information about this product.

If some technical parameters for the device (error, accuracy, measuring range, operating voltage and frequency) do not meet your requirements, please, e-mail me and I will negotiate with the manufacturer whether it is possible to deliver you a device on the desired specifications without a cost increase and in the shortest time.

On delivering the device, electric circuit diagrams and all technical documentation for operation, calibration and maintenance will be supplied. Also there will be documents that testify the accuracy and compliance with specifications.

In addition, translation of technical documentation into the customer’s language may be discussed.

            Delivery set

On delivering the device will be completely ready for use.

There are all necessary cables, adapters, sensors and spare parts as envisaged in technical documentation. Hence, there is no point in purchasing any additional repair & measurement equipment.

           Warranty

Warranty of this item - 12  month.

Before sending a device, all devices are checked whether they comply with all technical specifications.

Highly qualified metrology engineers carry out the check-up of every instrument at a specialized laboratory and with the help of master gages.

If necessary, we can send you photos or video with the check-up process. 

I ship only fully working devices complying with all parameters.

The warranty for this device is 1 year from the date of shipment from my warehouse.

Within 1 year term I will provide the repair of the device for free in case of manufacturing defect or when the technical parameters do not comply with technical documentation. You will have to pay only for delivery. 

When a device is out of order due to your fault (its fall, it is flooded with water, the power supply does not meet the specified technical requirements, input signals exceed the norm, etc.) or there are conspicuous marks of casing opening (broken warranty labels), it is considered a non-warranty repair.

Within 1 year term we can advise you for free on the device operation.


          After-warranty service

After warranty termination I can arrange a paid repair and technical maintenance of a device as well as I can sell you all necessary spare parts for repair at minimum prices. I always have them in stock.

           Packaging

Immediately after checking, the device will be wrapped in several layers of strong air-bubble film and placed into a strong cardboard box. Extra cardboard plates will be used for fixation.

If necessary, wooden box or pallet may be used. For a more reliable fixation foam can be applied. The whole box will be placed in a waterproof polyethylene bag which will be wound with several layers of packing tape.

A special handle will be made for ease of transportation.

Thus, I guarantee qualitative and conscientious packing of the device that reduces to minimum the possibility of damage during transportation.

         Discount (from-10% to -90%)

I suggest you a device which is unique in its class and price category with the following specifications: (accuracy, measurement range, error, temperature operating conditions), endurance and durability (military performance, aluminum, stainless steel, titanium or carbolite casing, shock and vibration resistance, high maintainability and reliability), free measuring kit (cables, adapters, load, fuses, etc.), 1year warranty.


Unused cheap devices with the same specifications, accuracy and durability do not exist.

If you consider the price for this device unreasonably high, and you know the similar equipment at a lower price, please, let me know.

I will help you to compare these two models. In case your model (which is cheaper) is the same as the device I suggest or even it is better, then
I guarantee to sell you a unit at that cheaper price with additional 10% discount.
