Manual of product DEM900
Editorial note
The Velleman DEM900 is a thermometer that stands out for its wide temperature range of -40 to 70 °C, allowing for reliable use in various environments. Its LCD screen with backlighting ensures optimal visibility even in low-light conditions, although clarity may not match modern display technologies such as OLED screens. In terms of performance, it offers a measurement accuracy of 2 °C, but the margin of error of ±4 % may be insufficient for professional users or those requiring very precise measurements. Nevertheless, features such as the humidity range of 10 to 95 % ensure reliable results. The compact and lightweight design, with a weight of 575 g, makes handling easy, but some users may find this device relatively heavy for prolonged use. Furthermore, while the 9 V battery power supply ensures optimal performance, reliance on this energy source may increase long-term usage costs. In summary, the Velleman DEM900 is a solid choice for those seeking a reliable thermometer with varied features, but it may not be suitable for all users, particularly those who demand extreme accuracy or maximum portability.Score details
