The Multitester, model THOR 3620, is a portable, multipurpose, digital instrument for measuring temperature, relative air humidity, oxygen concentration and radiance for phototherapy. The radiometer function enables selecting the type of light source to be measured.
It is a light, ergonomic and compact device that is ideal for routines in ICUs, delivery rooms and joint accommodations, among other sectors of hospitals and clinics, and which permits checking whether the treatment is being administered at satisfactory levels.
The THOR meets the needs of Clinical Engineering and Maintenance teams for routine control or occasional checks.
