  • Coating Thickness Tester

    Extech CG204 - Extech Instruments Corporation

    The Extech CG204 is a portable meter designed for non-invasive coating thickness measurements with automatic recognition of ferrous and non-ferrous substrates. The tester uses dual technology to indicate ferrous (magnetic induction measurement) and non-ferrous (eddy current measurement) substrates. It features single and continuous measurement modes as well as direct and group working modes, 400-reading memory storage, and user-programmable high/low alarms. The CG204 comes with two AAA batteries, USB cable, software, calibration iron, calibration aluminum, precision standards, pouch case, and user manual.

  • Coating Thickness Tester

    Extech CG104 - Extech Instruments Corporation

    The CG104 is a pocket-sized coating thickness tester which offers quick one-handed operation and non-destructive measurements of the thickness of ferrous and non-ferrous substrates. Its unique reversible display allows you to take readings in challenging angles of area being measured, plus it has an easy-to use menu system and backlit display feature. Built-in memory stores/recalls up to 255 readings. Complete with two AAA batteries, calibration standards (one ferrous plate, one non-ferrous plate and one standard coating plate film), wrist strap and soft case.

  • Type K/J Single Input Thermometer

    Extech TM100 - Extech Instruments Corporation

    The Extech TM100 Type J/K Single Input Thermometer has a wide temperature range of -328 to 2501°F/-200 to 1372°C for type k and -346 to 2012°F / -210 to 1100°C for type j measurements. It has a high 0.1°/1° resolution and a large backlit LCD display with readouts in °F, °C, or Kelvin. The data hold function freezes the reading on the display and the screen displays the Max/Min/Avg. Readings capture a relative time stamp. Also, the offset key is used for zero function to make relative measurements. Auto power off with a disable feature. This thermometer comes complete with the Type K bead wire temperature probe and one 9V battery.
