DeFelsko PosiTest DFT Coating Thickness Gauge

DeFelsko announces the new PosiTest DFT Coating Thickness Gauge, ideal for in-shop checking of coating thickness in automotive, welding, or blast shops, or powder coating operations. PosiTest DFT Ferrous measures coating thickness up to 40 mils on ferrous metals such as steel, while PosiTest DFT Combo measures paint thickness on all metals, including steel, aluminum, and stainless steel substrates.

PosiTest DFT Coating Thickness Gauge is an economical, DeFelsko-quality electronic gage for measuring dry film coating thickness on all metal surfaces.


PosiTector RTR-P Replica Tape Reader Probe

DeFelsko announces the release of the new PosiTector RTR-P Probe, for reading the surface profile taken with Testex Press-O-Film Replica tape, as well as measuring the peak density of the sample taken. When connected to the Advanced PosiTector Gauge Body, the new RTR-P Probe also generates black and white, two-dimensional and colour, three-dimensional images of the replica tape specimen, allowing the images to be incorporated with the profile and peak count measurements in reports.

PosiTector RTR-P also generates a hi-resolution SDF (surface data file) that can be imported into third-party software, resulting an a 3D map of the blasted steel surface.


eChlor*Test Kit for Chlorides on Surfaces

New! Chlor*Rid International announces their new  eChlor*Test Kit  for electronic measurement of surface chloride contamination. Self-contained, simple-to-use ChlorTest Kit with digital display and data-logging for 500 tests of soluble salts on surfaces.


DeFelsko PosiTector SHD Shore Hardness Tester

Introducing DeFelsko's NEW PosiTector SHD Shore Hardnesss Durometer handheld electronic instrument that measures the indentation hardness of non-metallic materials. Two models are available for different hardness ranges - Shore A and Shore D.


Time Instruments' TR100 Plus Surface Roughness Tester

New! TR100-Plus by Time Instruments, supercedes their TR100 Surface Roughness Tester. Measure, display, and process surface roughness measurements of flat, round, or sloping surfaces, as well as grooves up to 3.1 x 1.2 inches. in Ra or Rz units.


TQC CurveX3 Basic Oven Logger

TQC announces its new CurveX 3 Basic Oven Logger; a basic 4-channel oven recorder designed for everyday use in powder coating lines. Simple to use and economical for any powder shop.


PosiTector SST Soluble Salt Tester

DeFelsko introduces its new PosiTector SST Soluble Salt Tester for measuring soluble salt contamination on metal surfaces. PosiTector SST is a conductivity probe designed specifically for the Bresle Method of salt testing, and is compatible with any Bresle Patch, including DeFelsko's new PosiPatch and the proprietary DeFelsko Patch.


DeFelsko PosiTest LPD Low Voltage Pinhole Detector

DeFelsko announces its new PosiTest LPD Low Voltage Pinhole Detector! It uses a wet sponge to detect holidays, pinholes and other discontinuities on metal and concrete substrates without damaging the coating


DeFelsko SST Bresle Method Salt Test Patches

DeFelsko's new PosiTector SST Soluble Salt Test probe offers four Bresle method patch options for measuring soluble salts on surface prior to the application of protective coatings: the economical DeFelsko Patch, the latex Bresle patch conformable to ISO 8502-6, the patented new PosiPatch reusable silcone Bresle-method patch with either a magnetic aluminum ring or their newest Flexible Magnetic Ring.


DeFelsko PosiTector Dewpoint Meter Probes

DeFelsko's PosiTector DPM Dew Point Meter Is the ideal tool for measuring environmental parameters on the job site, paint shop, or manufacturing floor. Choose from four available probe options:

DPM   - measures air temperature, relative humidity, and dewpoint, with integral surface temperature probe

DPMS - measures air temperature, relative humidity, & dewpoint, with separate, K-type magnetic surface temperature probe (other K-type probes available)

DPMA - new! - measure ambient temperature, relative humidity, dewpoint, surface temperature, with hot-wire anemometer to measure wind speed

DPMD - new! - measures dew point, relative humidity, and air temperature, with sintered aluminum housing and ½" NPT threads for insertion into tanks & pipes (max 200 psi / 1.3 MPa)
