525 Thermograph

This electronic bimetal thermograph is engineered for accurate, long-term temperature monitoring, combining precision electronic control with a compact, thoughtfully designed recording mechanism. Operating over a broad temperature range of –15 to +65 °C, it is well suited to professional and technical environments where consistent, clearly recorded data is essential.

At its core, an electronic quartz clockwork provides selectable recording cycles, allowing daily (25.6 h), weekly (176 h), or monthly (783 h) revolutions to be chosen as required. The movement operates autonomously for up to 12 months on a standard LR6 battery and delivers a measurement accuracy of ±0.5 K, ensuring stable and dependable temperature recording over extended periods.

Temperature data is recorded on a precision drum with an 80 mm recording height. The drum is manufactured from durable plastic, offering both structural stability and resistance to corrosion. With a diameter of 93.3 mm and an overall height of 93 mm, the thermograph maintains a compact footprint without compromising legibility or performance.
