Liquid environment thermometer TFA 14.4003.02.01, -45–50 °C, white, 210×30×20 mm
The TFA liquid environment thermometer model 14.4003.02.01 is a compact analog thermometer designed to measure ambient temperature in degrees Celsius within a range of -45 to 50 °C. Housed in a white plastic casing measuring approximately 210×30×20 mm, this device provides clear liquid-column readings for simple and reliable monitoring of indoor and protected outdoor environments such as rooms, greenhouses or storage areas where a visual temperature reference is sufficient.
This thermometer features a durable plastic housing that is lightweight and easy to mount. The liquid-column display gives immediate, continuous readings without batteries or electronic components, making it low-maintenance and reliable in long-term applications. The device includes marked freezing zones to help identify temperatures around the freezing point at a glance. Its compact dimensions allow installation in narrow spaces or on walls, windows and other flat surfaces.
Mount the thermometer on a vertical surface or place it where it is protected from direct sunlight, strong drafts and radiators to obtain representative ambient temperature readings. Allow the device to stabilize for several minutes after installation or after moving it between locations before reading the liquid column. Read the temperature value at the top of the liquid column, aligning your sight with the level for the most accurate visual reading. No power supply or calibration is required for normal operation.
For consistent measurements, position the thermometer at a typical room height away from heat sources and direct sun. Use the marked freezing zones to quickly detect conditions near 0 °C. Clean the plastic housing with a soft, damp cloth and avoid abrasive cleaners to preserve markings and casing integrity.
