The TQC DewCheck 4 - Dewpoint Meter (DPM)/ Dewmeter is an extremely versatile dewpoint meter to measure and record all climate parameters required to treat surfaces. This easy to use and robust dewmeter conforms to ISO 8502-4 & ASTM D3276-07 and measures the relative humidity (%RH), ambient temperature (Ta) and surface temperature (Ts) and calculates the dewpoint temperature (Td) and the difference between the dewpoint temperature and the surface temperature (ÄT). The difference between the surface temperature and dewpoint temperature indicates the optimal climate conditions for painting. All parameters can be stored in the dewmeter's memory, tagged with a date and time.

For communication between DewCheck 4 dewmeter and a PC the DewCheck dewmeter USB cable is standard supplied. To analyze the data the DewCheck 4 comes with the special Ideal Finish Analysis software. This software is the most advanced temperature and humidity monitoring software package for Dewpoint Meters available today. It offers user friendly reporting functions for standard production work as well as advanced calculations for in depth analysis of the climate parameters prior to coating. Detailed graphic representations and customizable reports help to make the right decisions.

The TQC Bresle Kit - Chloride Test Kit complies with the ISO 8502-6 and ISO 8502-9 standards that describe the Bresle Method to assess the level of soluble salts using a Bresle patch or Bresle sampler, distilled water and a conductivity gauge. The conductivity is mainly directly proportional to the concentration of dissolved chloride ions in the solution. The kit includes all the necessary equipment to execute a bresle test that will indicate the contamination of soluble salts on blast-cleaned surfaces prior to coating. Inside the TQC Bresle Kit - Chloride Test Kit is a conductivity gauge used for the assessment of soluble salt ions as chlorides, sulphates and nitrates. Contamination of blast-media The TQC Bresle Kit - Chloride Test Kit is also suitable to determine the contamination of blast-media in use. This important test described in the ISO 11127-6 and ISO 11127-7 standards helps to prevent that the dissolved salts in the recycled abrasive media or water will not re-contaminate the surface being cleaned.


Robust, handheld rechargeable inspection spotlight with a power density at the hot spot of 10,000uW/cm2 and 1500uW/cm2 at 38cm (15") The TQC UV inspection lantern is used to detect contaminations that react under UV-illumination and cannot be seen with naked eye such as some organic fats, alkaline contaminants etc.. Ideal to inspect the cleanliness of steel prior to painting. Delivered in a sturdy plastic suitcase complete with yellow safety glasses for optimal contrast. Recharger included. Wavelength : 365 nm LED lifetime: 20,000 hours Runtime (fully charged): approximately 3 hours


The TQC Dust Test Kit according to ISO 8502-3 allows assessment of the quantity and size of dust particles on surfaces prepared for painting. Dust on blast cleaned surfaces can reduce coating adhesion, leading to premature coating failure and sub-standard coating finish. The dust test kit can be used in accordance with the recommendations of BS EN ISO 8502-3 either as a pass/fail test or as a permanent record of the presence of dust. Dust Test KIT Standards ISO8502-3 Features TQC Dust Test KIT A strong binder holds all necessary forms and visual comparator and has an integrated compartment for tape, scissors and illuminated magnifier. The binder closes with Velcro-strips to secure the content. Report Forms have space for 5 different test results. All the information that the ISO8502-3 standard requires can be filled in through check boxes or in pre-defined areas. This guarantees complete and valid reports. Display board shows clearly the different quantity ratings but also has a unique size-comparator for both light and dark dust particles. A black and white contrast files is included as well. The pictorial manual shows the test method in a clear way and can be used in any “language”. The Sample Transfer sheet is made of scratch resistant, high transparent plastic with pre-printed positions. It is conveniently fixed by a Velcro strip for easy detachment and replacement. The strong binder is suitable for field use. It holds all forms and accessories and is locked by a Velcro strip. No loose items!
