Extech
Extech, part of FLIR, covers general-purpose handheld test instruments, and this catalogue carries multimeters, pH and conductivity meters, light and sound meters, air flow instruments and clamp meters.
The line is aimed at maintenance, facilities and field survey work where one instrument often has to cover several parameters. For the electrical products, check the safety category rating against the circuits involved, since that is a genuine safety specification rather than a marketing figure. For light and sound meters, confirm the correction and class rating if the reading has to support a compliance report.
