To ensure that your TECHKON measurement device is functioning properly and meets our strict international standards, we recommend it be evaluated every 24 months at a TECHKON Service Center. (Check date of manufacturing printed on the last page of the user’s manual to determine if evaluation is due.)

The TECHKON 24 month preventive maintenance program for the SpectroPlate, SpectroDens, RYOBI PDS Series, RS400, 800 and SpectroDrive is a comprehensive check up consisting of the following tasks:

• Clean instrument
• Verify charging capability
• Exchange battery (if necessary)
• Dispose old battery
• Check measurement lamp and exchange (if necessary)
• Check absolute white standard
• Calibrate internal device
• Install new firmware
• Complete functionality test

Note: TECHKON offers a 24 month warranty on exchanged batteries and lamps

How it Works

Please contact us via telephone, email or facsimile, and specify whether you are returning your device for the Preventive Maintenance Program or due to a malfunction. If the device is being returned for a malfunction, please enclose a detailed description of the problem you are experiencing with the device and all of its accessories.

We will then issue a Return Material Authorization Number (RMA#) for your device. When shipping the device to the Techkon Service Center, please make sure the RMA number is displayed on the shipping container.

While conducting preventive maintenance services, if we encounter a malfunction of the unit we will provide a repair cost estimate and wait for your approval.

When a device is sent in for repair, there is a minimum $200 evaluation charge. If a repair is required and the cost exceeds $200, TECHKON will provide a repair cost estimate and wait for your approval. Published repair prices do not include shipping.
