Using an ergonomic and lightweight design, the Lighthouse Handheld 3013 is ideal for use where a smaller lightweight handheld counter is needed. Offering 3 channels of simultaneous particle counting, the Handheld 3013 displays both cumulative and differential particle count data on its easy to read 2.7” (6.8 cm), 128x64 OLED screen. It’s rechargeable battery allows up to eight hours of continual operation. Easily download data via its USB port using the Lighthouse Data Transfer Software, LMS XChange. The Handheld 3013 will monitor particulate levels accurately and reliably, even in those “hard-to-reach” areas where two-handed operation is unsafe.
