TQC Sheen DewCheck 4 Series 2 – Dewpoint Meter

The TQC DewCheck 4 Series 2 dewpoint meter is a versatile dewcheck meter that measures and records the important climate parameters required to treat surfaces effectively. 


Brought to you by TQC Sheen, our specialist testing brand, this robust, portable dewpoint meter is relied upon across the coatings, construction, building maintenance, marine, and steel production industries.  

It’s a handheld dewpoint meter that measures relative humidity (%RH), ambient temperature (Ta), and surface temperature (Ts).  In addition, it calculates the dewpoint temperature (Td) and the difference between the calculated dewpoint temperature and the measured surface temperature.

Long term reliable sensors

Our dewpoint meter’s high-end industrial humidity and temperature sensors and sophisticated calibration procedures guarantee the highest accuracy for up to two years. 

Dewpoint meter connectivity 

Your DewCheck 4 meter communicates effortlessly with your PC and the Ideal Finish Analysis software via the USB cable that’s supplied as standard.  

Our Ideal Finish Analysis software gives you complete control over your collected DewCheck data with user-friendly reporting functions for standard production work and advanced calculations for in-depth analysis. While the detailed graphic representations and custom reports guide you in making the best decisions possible. Download the Ideal Finish software here.

Optimal dewpoint testing as standard

Compatible with a range of international standards including ISO 8502-4, ASTM D3276-05, BS 7079-B4.

Dewpoint meter carry case

Supplied in a robust and ergonomic leather pouch to protect against damage from daily use.
