We integrate scientific research, development, production, sale and service in one company. Our custom moisture indicators products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM moisture indicator products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

The Model 1103 Moisture Indicator is an easy to read "analog" style moving needle meter with printed scales for measuring moisture content in concrete materials. It is a 2.5% accuracy class, precision instrument, which is calibrated for measuring moisture content in concrete and other surface. It uses non-penetrating, non-invasive, surface contact based measurement. It has a large easy to read display and does not suffer from the reading interpretation issues of many digital moisture meters.
The meter has an on - off switch and a 'CAL' (Calibration) knob. The switch should be turned to the 'OFF' position whenever the instrument is not being used. The 'CAL' knob must be adjusted prior to use with the meter sitting on a calibrator plate until the dial reads 'full scale' (fully to the right hand side line Cal / 10).
